93	Spreading Behavior of Oil on Hierarchical Microstructured PET Surfaces Fabricated Using Hot-Embossing Combined with Laser-Based Methods Bouchard, Felix, Soldera, Marcos, Lasagni, Andrés Fabián 06 November 2024 (has links) In this study, the wetting behavior of microstructured polyethylene terephthalate (PET) foils for polar and nonpolar liquids produced by plate-to-plate hot embossing is investigated. For the embossing step, stainless steel plates are used as stamps, which are microstructured with single-scaled and hierarchical textures using direct laser writing and two-beam direct laser interference patterning. The imprinted microstructures, containing pillar- and line-like textures, show increased water contact angles combined with a superoleophilic behavior. Time-resolved measurements reveal that oil droplets spread rapidly on the hierarchical textures with velocities of up to 1.4 mm2 s−1. This functionalization of PET foils creates new opportunities for a wide range of industrial applications, such as the use of oil-based instead of solvent-based paints, an improved distribution of lubricants in mechanical components or for oil–water separation in maritime surroundings. info:eu-repo/classification/ddc/540 ddc:540 info:eu-repo/classification/ddc/600 ddc:600

Busca oferecer maiores subsídios sobre um tema que só recentemente tem sido melhor estudado, dada a sua ligação com o meio ambiente e a polêmica sobre o desenvolvimento sustentável. / This thesis researched about recycling in Brazil highlighting four of the most significatives recyclily solid residues, e.g. tin (aluminium) cans, paper, bottles made of polyethylene terephthalate (PET) and the glass. Due to its liaison with the environment and the controversies about the sustainable development, this thesis offer great subsidies about a theme that only recently has been deeply studied.
