Polymerization-induced microphase separation (PIMS) is a process where an emergent block polymer formed in a polymerization mixture in situ spontaneously undergoes microphase separation at a critical conversion to produce versatile nanostructures. Typically, reversible addition-fragmentation chain transfer (RAFT) copolymerization of a monomer and a crosslinker in the presence of a macro-chain transfer agent (macro-CTA) is used to yield a crosslinked block polymer consisting of a bicontinuous disordered morphology at nanometer scale with precise control of the domain size. Taking advantages of the bicontinuous morphology for transport and mechanical integrity, I will discuss recent examples of polymer membranes for environmental and energy applications by combining suitable polymers in the PIMS system, including porous polymers derived from polylactide, which is one of the most well-known polymers produced from renewable resources and easily degraded under basic condition. |
