Abstract
MéTODO E PROCESSO PARA PRODUZIR FILME FINO NANOESTRUTURADO E AUTOLIMPANTE SOBRE A SUPERFìCIE DE LENTES E DISPOSITIVOS óPTICOS. Descreve-se um método e processo para produzir filme fino nanoestruturado, com propriedade autolimpante, para ser aplicado diretamente sobre a superfície de materiais transparentes com aplicação em componentes ópticos, notadamente em lentes de óculos ou, sobre filmes finos com função anti-reflexo préviamente depositados sobre estes materiais; sendo que o revestimento de filme fino possui a propriedade autolimpante contra substâncias orgânicas que possam vir a impregnar a referida superfície; e onde a citada propriedade autolimpante tem como princípio a atividade fotocatalítica de oxidação, intrínseca e expontânea, promovida na presença de dióxido de titânio (TiO~ 2~), e exposição a radiação eletromagnética; onde o processo específico que implementa o método garante obtenção de camada de filme fino, nanoestruturado e homogêneo, após imersão e retirada lenta do substrato de suspensões coloidais preparadas com álcoois, vernizes e as nanopartículas de dióxido de titânio; sendo o método de precursores poliméricos modificado utilizado na produção das nanopartículas de dióxido de titânio, com a quelação por ácido cítrico de cátions de titânio gerados em hidrólise prévia do precursor tetraisopropóxido de titânio, e com posterior calcinação do éster formado pela adição de etilenoglicol a solução de citrato de titânio; resultando em nanopartículas de dióxido de titânio com alta cristalinidade e preponderância da estrutura cristalina anatase, alta reatividade e excelente qualidade óptica.
