Abstract
A nanocomposite membrane includes a polymer phase, a nanowire phase, and a pore phase. The polymer phase includes a polymer including a cyclic imide group. The nanowire phase includes metal oxide nanowires. Each of the polymer phase and the nanowire phase is uniformly distributed within at least part of the nanocomposite membrane.
Claims26
A nanocomposite membrane, comprising:
- a polymer phase comprising a polymer comprising a cyclic imide group;
- a nanowire phase comprising metal oxide nanowires;
- and
- a pore phase,
- wherein each of the polymer phase and the nanowire phase is uniformly distributed within at least part of the nanocomposite membrane.

A method of making a nanocomposite membrane, comprising:
- (A1) mixing a water-insoluble polymer composition, water-soluble pore-forming polymer composition, and metal oxide nanowires in a non-aqueous solvent to form a mixture, the water-insoluble polymer composition and the water-soluble pore-forming polymer composition being dissolved in the non-aqueous solvent, the non-aqueous solvent being miscible with water;
- (A2) casting the mixture onto a substrate to form a film;
- (A3) immersing the film in a water bath, such that the water-soluble pore-forming polymer composition and the non-aqueous solvent diffuse from the film into the water bath;
- and
- (A4) drying the film.
