High-Selectivity Polysiloxane Membranes for Gases and Liquids Separation (A Review)

Abstract The most promising approaches to making polysiloxane-based membranes more selective are considered. These can be subdivided into three groups: (1) development of new membrane materials by copolymerization, (2) modification the polysiloxane chain (in backbone and pendant chains), (3) mixed matrix membranes. All subjected a critical analysis, conclusions made on prospects for high-selectivity high-performance based them. data presented from viewpoint applied aspects
