Stimuli responsive block copolymers have been drawn interests in various fields, due to their ability to change structures and physical or chemical properties in response to external stimuli. Poly(N-isopropylacrylamide) (PNIPAM) is a representative polymer showing LCST behavior in aqueous solution, and catechol functional group is known to be able to undergo metal ion chelating. In this study, we've designed dual responsive block copolymers consisting of thermo-responsive PNIPAM and metal ion-responsive poly(dopamine acrylamide) (PDA). Reversible addition-fragmentation chain transfer (RAFT) polymerization was used to synthesize adverted amphiphilic block copolymer PNIPAM-b-PDA, and its self-assembled morphology transition depending on temperature and metal ion concentration change was studied. |
