摘要

Crosslinking is widely applied in polymer membranes for gas separation, which establishes the network of polymer chains and changes the free volume distribution of membranes by thermal crosslinking, photo crosslinking and ionic crosslinking. In this review, types of different organic crosslinkers and crosslinking methods are reviewed. We also briefly summarize the influence of crosslinking on gas permeability of membranes in different crosslinking systems, respectively.
