Membranes from Block Copolymers

Pp. 148-162 (15)

Abstract

Nanotechnology with its “bottom-up” approach gives many opportunities to the membrane science and technology community for the developing advanced membranes. In this chapter, the fabrication of separation membranes from block copolymers is described. In addition, a strategy to manipulate the self-assembly of block copolymers is proposed highlighting the recent advances. As reported, the block copolymers offer exquisite nanostructures that lead to fabricate membranes with controlled pore size (nanopores), as well as dense films with tailored properties for CO2 capture.

Keywords:

Block copolymers, self-assembly, nanostructured membranes, controlled pore size, dense films, gas separation.
