Abstract
trata-se de uma peneira molecular de carbono (cms) de fibra oca assimétrica, peneira molecular que é produzida fornecendo-se uma solução de aditivo composta de uma poliimida e de um solvente, a uma temperatura superior a 250 °c que é menor do que o módulo de armazenamento a uma temperatura de 250 °c, mas não mais do que dez vezes menor, como medido utilizando a análise térmica mecânica dinâmica de 250 °c para uma temperatura em que a poliimida é carbonizada. a poliimida é conformada em uma fibra de poliimida oca, o solvente é removido, e a fibra oca de poliimida é aquecida para pirolisar a poliimida e formar a peneira molecular de carbono oca assimétrica. a peneira molecular de carbono de fibra oca assimétrica tem uma parede que é definida por uma superfície interna e uma superfície externa da referida fibra, e a parede tem uma região de suporte porosa interna que se estende da superfície interna até uma região de separação microporosa externa que se estende da região de suporte porosa interna até a superfície externa. surpreendentemente, quando a poliimida tem as características particulares do módulo de armazenamento, o método permite que a fibra oca de cms seja produzida sem quaisquer pré-tratamentos ou aditivos para inibir o colapso estrutural da região microporosa interna.
