Abstract
MEMBRANAS ASSIMÉTRICAS E MÉTODOS RELACIONADOS. A presente invenção se refere a membranas poliméricas microporosas e a métodos de fabricação relacionados. Uma modalidade de membrana microporosa assimétrica inclui, mas não se limita a, um substrato de polímero termoplástico definindo uma pluralidade de microporos, o polímero termoplástico incluindo um ou mais dentre polietileno (PE), polipropileno (PP), polimetil penteno (PMP) e uma combinação dos mesmos; e uma pele de polímero polimetil penteno (PMP) posicionada sobre o substrato de polímero termoplástico, sendo que, quando o substrato de polímero termoplástico inclui PMP, a pele de polímero PMP tem uma cristalinidade que difere da cristalinidade do PMP do substrato de polímero.
