Selective Swelling and Functionalization of Integral Asymmetric Isoporous Block Copolymer Membranes

SNIPS stands for a membrane fabrication technique that combines the evaporation induced self-assembly of block copolymers and classical nonsolvent phase separation. It is one-step readily scalable to fabricate integral asymmetric isoporous membranes. The prominent developments in last decade have carved out niche as potential next generation In decade, rich polymer library variety postmodification routes been successfully implemented membranes having desired pore functionality. Some these form soft nanochannels hydrated state due swelling wall, i.e., forming copolymer. These demonstrated perform several challenging separation tasks ultrafiltration nanofiltration. This paper highlights currently accessible functionality, strategies tune nanochannels, applications, future perspectives
