Acerca del papel y su potencial como configurador plástico

García González, María Dolores 21 March 2016 (has links)
[EN] This research work concentrates on the possibilities of paper as a material for creating pieces of artwork with volume in addition to considering it as an alternative to other kinds of paste with a longer tradition in sculpture. The main aim is to study the possibilities provided by this material for specific formal and structural aspects of the pieces of work. The study includes a review of the plastic materials used in sculpture, involving contributions from the most recent design materials. Paper is also presented here as a material and format, classifying it into different formal and aesthetic variants and demonstrating its possibilities as pulp and modelling paste¿and thereby its plastic capabilities¿in an attempt to put forward and establish new artistic practices. The research corroborates the use and long tradition of paper in the artistic world, including in works of volume, since there are many sculptures and ceramic artists much of whose work is created by making use of the properties of paper in any of its forms. One of the main examples is to be found in the East with the technique of origami, but in Europe this material's versatility and potential for creativity can be found with collage and cut-outs. Artists not only have the option of creating their own paper pulp and paste; thanks to development in the industry and research, today the market offers a wide range of papers and paper-based pastes that harden in air. These commercial pastes are easy to handle and maintain, and they provide a plasticity similar to ceramic pastes for modelling. As a modelling paste, paper meets the objectives that were initially set for the research. Among other aspects, it enables workpieces that last to be made quickly and economically; to find a more direct way of working on the piece that helps to ensure the artist's gestures are not lost in it; to reduce to the number of phases in the artistic production process; and to bring down material and energy costs. Furthermore, the paper added to different pastes used during the research has provided very beneficial properties to both the creative process and the aesthetics of the work or art. Notably, it is more resistant and lighter, as well as allowing for a great variety of shapes and finishes in the works created. In conclusion, one can affirm that the interactions between clay and paper are very positive and that paper pastes are a valid alternative to traditional pastes in certain plastic sculpture practices. Nevertheless, this relationship should not be considered as a replacement but rather a collaboration. Various possible lines of work have opened up following this research, such us introducing paper pastes as a practice in standard and non-standard education; creating one's own paper paste with commercial possibilities; and taking the results obtained further via a series of cultural activities that may enable the language learnt to be honed as well as raising awareness in current artistic circles. / [ES] La presente investigación se centra en las posibilidades del papel como material para la creación de piezas volumétricas, planteándose además, como una alternativa a otras pastas de mayor tradición escultórica. Se fija como principal objetivo estudiar las posibilidades que otorga este material para ciertos aspectos formales y estructurales de las piezas. El estudio abarca una revisión de los materiales plásticos utilizados en escultura, en la que se incluyen las aportaciones introducidas por los materiales de diseño más actuales. De igual modo se presenta el papel como material y formato, clasificándolo en diferentes variantes formales y estéticas mostrando sus posibilidades como pulpa y pasta de modelado y, por consiguiente, en sus capacidades plásticas, pretendiendo ayudar a establecer nuevas prácticas artísticas. La investigación corrobora el uso y la gran tradición que tiene el papel en el ámbito artístico incluido el mundo del volumen, ya que son muchos los escultores y ceramistas que trabajan gran parte de su obra haciendo uso de las propiedades del papel en cualquiera de sus formas. Una de las primeras referencias la encontramos en Oriente gracias a la técnica del origami, pero también en Europa con el collage o los recortables, se pone de manifiesto la creatividad y la versatilidad de este material. El artista no sólo cuenta con la opción de elaborar su propia pulpa y pasta de papel, actualmente gracias al desarrollo de la industria y al de la investigación, el mercado ofrece gran variedad de papeles y pastas con base de papel que endurecen al aire. Estas pastas comercializadas son de fácil manejo y mantenimiento y ofrecen durante su modelado, una plasticidad similar a la de las pastas cerámicas. Como pasta para modelar, el papel cumple con los objetivos inicialmente planteados en la investigación permitiendo, entre otros aspectos, el obtener piezas de rápida ejecución, económicas y duraderas; encontrar una forma de trabajo más directa sobre la obra que ayude a no perder la marca del gesto del artista sobre la misma; reducir el número de fases en la producción artística y abaratar los costes energéticos y de material. Por otro lado, el papel añadido a las diferentes pastas trabajadas durante la investigación, ha aportado características muy beneficiosas tanto en el proceso creativo como en el resultado estético de la obra. Destacando una mayor resistencia y ligereza, así como la admisión de gran variedad de formas y acabados por parte de las piezas realizadas. En conclusión, es posible afirmar que las interacciones entre arcilla y papel son muy positivas y que las pastas de papel son una alternativa válida a las pastas tradicionales en determinadas prácticas escultóricas. Sin embargo, esta relación no debe considerarse una sustitución sino más bien una colaboración. Tras esta investigación se abre una serie de líneas de trabajo como puede ser la incorporación de las pastas de papel como práctica para la formación reglada y no reglada; la elaboración de una pasta de papel propia, con posibilidades comerciales; y el ahondar en los resultados obtenidos mediante una serie de acciones culturales que permitan agilizar el lenguaje aprendido así como darlo a conocer en los círculos artísticos actuales. / [CA] La present investigació es centra en les possibilitats del paper com a material per la creació de peçes volumètriques, plantejant-se a més a més, com una alternativa a altres pastes de més tradició escultòrica. El principal objectiu es estudiar les possibilitats que dona aquest material per aconseguir determinats aspectes formals i estructurals de les peçes. L'estudi fa una revisió dels materials plàstics utilitzats en l'escultura, en la que s'inclouen les aportacions introduïdes pels materials de diseny més actuals. De la mateixa manera es presenta el paper com a material i format, es classifica en diferents variants formals i estètiques mostrant les seues possibilitats com pulpa i pasta de modelat i, conseqüentment, en les seues capacitats plàstiques, intentant ajudar a establir noves pràctiques artísitques. L'investigació confirma l'ús i la gran tradició que té el paper a l'ambit artístic inclós el món del volum, ja que son molts els escultors i ceramistes que treballen gran part de la seua obra fent ús de les propietats del paper en qualsevol de les seues formes. Una de les primeres referències la trobem a Orient gràcies a "la tècnica del origami", però també a Europa amb el collage o els retallables, es posa de manifest la creativitat i la versatilitat de aquest material. L'artista no solament conta amb l'opció d'elaborar la seua propia pulpa i pasta de paper, en l'actualitat gràcies al desenvolupament de l'industria i la investigació, el mercat ofereix gran varietat de papers i pastes amb base de paper que fa dur l'aire. Aquestes pastes comercialitzades son de fàcil tractament i manteniment i ofereixen durant el seu modelat, una plasticitat similar a la de les pastes ceràmiques. Com a pasta per modelar, el paper cumpleix amb els objectius inicialment plantejats en l'investigació permetent, entre altres aspectes, obtenir peçes de rápida execució, econòmiques i perdurables; trobant una forma de treball més directa damunt l'obra que ens ajude a no perdre la marca del gest de l'artista sobre ella; reduïr el nombre de fases a la producció artística i minvar els costes energètics i de material. D'altra banda, el paper barrejat amb les diferents pastes treballades durant l'investigació, ha aportat característiques molt beneficioses, tant en el procés creatiu com en el resultat estètic de l'obra. Destacant una major resistència i lleugueresa, així com l'admissió de gran varietat de formes i acabats per part de les peçes realitzades. En conclusió, es possible afirmar que les interaccions entre argila i paper son molt positives i que les pastes de paper son una alternativa vàlida a les pastes tradicionals en determinades pràctiques escultòriques. No obstant, aquesta relació no ha de considerar-se una subsittució sino més bé una col·laboració. Després d'aquesta investigació s'obri una sèrie de línies de treball com pot ser l'incorporació de les pastes de paper com a pràctica per la formació reglada i no reglada. L'elaboració d'una pasta de paper pròpia amb possibilitats comercials; i aprofundir en els resultats obtinguts mitjançant una sèrie d'accions culturals que agilitzen el llenguatge aprés, així com donar-ho a conéixer en els cercles artísitics actuals / García González, MD.

The combination of these structures can lead to significant improvements in their properties through the synergism of the two species. Methylene blue, a cationic dye widely used in many types of industries, has considerable toxicity and causes biological imbalances when discarded in the wrong way. Because it is a low-cost, high-application material, it is of great concern to health organizations as it can cause irreversible damage when discarded or stored in the wrong way in the environment. Thus, the need for treatments to remove this material from nature becomes more and more and among the various available techniques, the adsorption is one of the most outstanding, due to its ability to remove the material from the contaminated medium without compromising the medium, however the materials currently used have a number of disadvantages, such as high cost and considerable efficiency. The purpose of this work was to obtain and characterize a hybrid material consisting of the deposition of graphene oxide (GO) under porcelain based on a mixture of clay and paper, and its application as adsorbent material of the dye methylene blue. The kinetic studies showed that hybrid materials with different proportions of GO (400μL and 1200μL) were tested as adsorbent matrices, showing in their results that the higher proportion of GO in the compound improves the adsorption power, reaching 98% of the dye, due to the high surface area of the carbonaceous material and its negative charge surface are attractive for the retention of the cationic dye, since the interaction between the materials is given primarily by electrostatic attraction. Another factor that influenced the retention power of the dye in the matrix was the basic medium in which the dye was, since when it immersed the matrix, the molecules of methylene blue began to interact with it. The use of paper clay as an adsorber matrix also allowed the reuse and recycling of the matrices, since after the first use there were still active sites in the matrices and after their saturation, sintering them again it was possible to eliminate the materials of its surface, allowing so its re-use with GO deposited again. / Materiais à base de óxido de grafeno e diferentes tipos de argilas são duas classes de materiais com propriedades únicas e com diversas aplicações, destacando a capacidade de adsorção de alguns corantes, metais e compostos orgânicos. A combinação destas estruturas pode levar a melhorias significativas em suas propriedades, através do sinergismo das duas espécies. O azul de metileno, um corante catiônico muito utilizado em diversos tipos de industrias, apresenta toxicidade considerável, além de causar desequilíbrios biológicos quando descartados de maneira equivocada. Por se tratar de um material de baixo custo e de grande aplicação, ele demonstra uma grande preocupação para as organizações de saúde, uma vez que podem causar danos irreversíveis quando descartados ou armazenados de forma equivocada no meio ambiente. Sendo assim a necessidade de tratamentos para remover este material da natureza se torna cada vez maior e dentre as diversas técnicas disponíveis a adsorção é uma da que mais se destaca, devido a sua capacidade de remover o material do meio contaminado sem comprometer o meio, porém os materiais utilizados atualmente apresentam uma série de desvantagens, tais como alto custo e eficiência considerável. Sendo assim este trabalho teve como finalidade a obtenção e caracterização de um material híbrido constituído pela deposição de óxido de grafeno (GO) sob uma porcelana baseada em mistura de argila e papel (paper clay - PC), e sua aplicação como material adsorvente do corante azul de metileno. Através de estudos cinéticos, os materiais híbridos com diferentes proporções de GO (400μL e 1200μL) foram testados como matrizes adsorventes, mostrando em seus resultados que a maior proporção de GO no composto, melhora o poder de adsorção, chegando a 98% de retenção do corante, devido a elevada área superficial do material carbonáceo e sua superfície de carga negativa são atrativos para a retenção do corante catiônico, uma vez que a interação entre os materiais se dá primordialmente por atração eletrostática. Outro fator que influenciou o poder de retenção do corante pela matriz foi o meio básico em que o corante se encontrava, uma vez que quando imersa a matriz, as moléculas de azul de metileno passaram a interagir com a mesma. A utilização do paper clay como matriz adsorvedora permitiu ainda a reutilização e reciclagem das matrizes, uma vez que após a primeira utilização ainda restaram sítios ativos nas matrizes e após a sua saturação, sinterizando-as novamente foi possível eliminar os materiais de sua superfície, permitindo assim a sua reutilização com GO depositado novamente.
