Dissertação (Mestrado em Engenharia Mecânica) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2015.https://repositorio.ufrn.br/jspui/handle/123456789/20440Innovative methods in the textile segment is currently responsible for increase in production processes, development of new materials and add new technologies in an area that was one of the major participants in the industry revolution. Thus, much research has been responsible for putting the textile industry in the new era of technological revolution watching so, the dynamism of microelectronics companies, food, and mechanics, among others. To this end, this PhD project aims to add value research involving new textile materials. Thus, this project aims to make the synthesis and characterization of a silver doped titanium dioxide nanocoating on polyester fabric in order to develop a functional textile material with self-cleaning application. A physical vapor deposition technique (PVD) was used as the method of synthesis. The selection of the support material and the technique used in obtaining the nanocoatings are variables that can influence their functional properties, uniformity and adhesion. The textile fibers are materials used as substrate by having greater flexibility to be easily adaptable to any geometry and low cost. The efficiency of the photocatalytic activity of the material was confirmed by discoloration of the dye Acid Blue 113 through UV radiation sources, using absorption spectroscopy (96%). The presence of Ag and TiO2 was confirmed by analysis of X-ray diffraction (XRD) photoelectron spectroscopy X-ray (XPS) and x-ray fluorescence (XRF). The surface morphology was evaluated through the techniques of atomic force microscopy (AFM) and scanning electron microscopy (SEM). Degradation of Acid Blue 113 dye molecule was confirmed by infrared spectroscopy Fourier transform (FTIR). The hydrophobic character of nanocoating was confirmed by contact angle measurement technique. The results show that the developed material has a high capacity self-cleaning pro pertiesporAcesso AbertoFotocatáliseDióxido de titânioDeposição física de vaporTêxtil funcionalNanorevestimentomasterThesisCNPQ::ENGENHARIAS::ENGENHARIA MECANICA
