Phase-separation member |
摘要 |
A phase-separation member comprises a porous substrate (11) containing void spaces, a microporous polymer material (14) which at least partially impregnates the porous substrate by entering into the void spaces, and a layer of a fluoropolymer applied to the outer face of the coagulated polymer material so that the layer (16) of fluoropolymer material remains predominantly at the surface.
