摘要:
The present invention pertains to a process for the manufacture of a porous membrane, said process comprising the following steps: (i) providing a composition [composition (F)] comprising: —at least one fluoropolymer [polymer (F)] comprising recurring units derived from at least one (meth)acrylic monomer (MA) having formula (I) wherein: —R1, R2 and R3, equal to or different from each other, are independently selected from a hydrogen atom and a C1-C3 hydrocarbon group, and —RX is a hydrogen atom or a C1-C5 hydrocarbon moiety comprising at least one functional group selected from a hydroxyl, a carboxyl, an epoxide, an ester and an ether group, and —at least one poly(alkylene oxide) (PAO); (ii) processing said composition (F) to provide a film; (iii) treating the film so obtained with an aqueous composition to provide said porous membrane. The present invention also relates to films and compositions used in said process, to porous membranes obtained from said process and to use of said porous membranes as separators in Lithium-ion batteries, as filtration membranes or in biomedical applications.
