Effect of Selective Solvents on Self-Assembly of Cationic Amphiphilic Triblock Copolymers Q-PVBC-b-PS-B-Q-PVBC

Abstract:

Self-assembly behavior of an cationic amphiphilic triblock copolymer Q-PVBC -b-PS-b-Q-PVBC in DMF/water and DMF/methanol were studied. Well defined triblock copolymer PVBC-b-PS-b-PVBC was synthesized by RAFT polymerization and the cationic amphiphilic block copolymers Q-PVBC-b-PS-b-Q-PVBC was obtained by the quaternization of hydrophobic precursors with triethylamine. It is concluded that that selective solvents had a great effect on the self-assemble morphologies of the polymer. Comparing to the micelles treating water as the selective solvent, the aggregates using methanol were irregular spheres and had larger diameter.
