No. of bitstreams: 1 Cristiane Mezaroba.pdf: 9118688 bytes, checksum: 7706a8529180fd844f20da89e3df3d57 (MD5) Previous issue date: 2017-02-23 / CAPES / Plasma sterilization present effective and extensive microbial lethality, fast action, compatibility with various materials, high diffusion through porous substances and are non-polluting systems. The objective of this study was to evaluate if the inductive RF plasma and N2-O2 mixture is efficient for use in sterilization of polymer medical-hospital and dental materials, represented in this study by the polymer HDPE. It was also the objective of this study to evaluate the possible superficial modifications of HDPE after sterilization. HDPE films were used with spores of Geobacillus stearothermophilus, with ≅5,73x107 UFC/film. In the microbiological tests were used 20W and 40W power, 0.5 Torr pressure and exposure times of 2,5,10,15 and 20 minutes. Low temperature was maintained (T<40°C), and the results demonstrated sterilization efficiency. The samples were characterized by contact angle measurements, atomic force microscopy (AFM), scanning electron microscopy field emission (FEG-SEM) and Fourier transform infrared spectroscopy in the "Attenuated Total Reflectance" (FTIR-ATR) mode. The active species formed in plasma were identified by a system of optical emission spectroscopy (OES). / A esterilização por plasma têm oferecido vantagens em relação a outros métodos à baixa temperatura utilizados, a começar por alta eficácia e abrangente letalidade microbiana, ação rápida, compatibilidade com vários materiais, alta difusibilidade e é um sistema não poluente. O objetivo deste trabalho foi avaliar se o plasma RF indutivo (ICP) e mistura de N2-O2 é eficiente para uso em esterilização de materiais poliméricos médico-hospitalares e odontológicos, representado neste estudo pelo polímero PEAD. Também foi objetivo deste trabalho avaliar as possíveis modificações superficiais do PEAD após a esterilização. Foram utilizados filmes de PEAD com esporos de Geobacillus stearothermophilus, com ≅5,73x107 UFC/filme. Nos testes microbiológicos foram utilizadas potências de 20W e 40W, pressão de 0,5 Torr e tempos de exposição de 2,5,10,15 e 20 minutos. Foi mantida baixa temperatura (T<40°C), e os resultados demonstraram eficiência de esterilização. Os filmes de PEAD após esterilização foram caracterizados por medidas do ângulo de contato, microscopia de força atômica (AFM), microscopia eletrônica de varredura por emissão de campo (FEG-MEV) e espectroscopia no infravermelho por transformada de Fourier no modo “Refletância Total Atenuada” (FTIR-ATR). As espécies ativas formadas no plasma foram identificadas por um sistema de espectroscopia óptica de emissão (OES).
