Abstract

resumo “artigos incluindo membranas de politetrafluoroetileno com fibrilas de serpentina” artigos, incluindo membranas de fluoropolímero expandidas com fibrilas de serpentina são fornecidos. as membranas de fluoropolímero exibem um elevado alongamento, mantendo substancialmente as propriedades de resistência da membrana de fluoropolímero. a membrana pode incluir um fluoropolímero e / ou elastômero. além disso, o artigo tem um alongamento de pelo menos uma direção de, pelo menos, cerca de 100% e uma resistência à tração da matriz de, pelo menos, cerca de 50 mpa. o artigo pode ser formado por (1) a expansão de uma fita extrudada de fluoropolímero seca em pelo menos uma direção para produzir uma membrana de fluoropolímero expandida e (2) retração da membrana de fluoropolímero expandida em pelo menos uma direção de expansão através da aplicação de calor ou por adição de um solvente. a aplicação de uma força de tração, pelo menos parcialmente, endireitam as fibrilas de serpentina, alongando assim o artigo. a membrana de fluoropolímero expandida podem incluir uma microestrutura substancialmente apenas de fibrilas. as membranas podem ser embebidas com uma material elastomérico para formar um composto.
