Polymerization-induced microphase separation (PIMS) is a process where a growth of a polymer chain from the end of a different polymer produces an emergent block polymer and spontaneously induces microphase separation in the polymerization mixture at a critical conversion. Typically, reversible addition-fragmentation chain transfer (RAFT) copolymerization of a monomer and a cross-linker in the presence of a macro-chain transfer agent (macro-CTA) produces yields a cross-linked block polymer consisting of a disordered bicontinuous morphology at a nanometer scale. In this talk, I will discuss how to control the domain size in the PIMS process towards fabrication of permselective membranes, and also our efforts to lower the limit of accessible pore size.
