Investigation on RAFT Polymerization of a Y-Shaped Amphiphilic Fluorinated Monomer and Anti-Fog and Oil-Repellent Properties of the Polymers

Abstract

A Y-shaped amphiphilic fluorinated monomer, 1-(1H,1H,2H,2H-perfluorodecyloxy)-3-(3,6,9-trioxadecyloxy)-propan-2-yl acrylate has been synthesized and its polymerization by reversible addition-fragmentation chain transfer (RAFT) homopolymerization has been investigated. The results show that the molecular weights of the polymers are controlled and all the molecular weight distributions are lower than 1.4. Well-defined copolymers with 2-(N,N-dimethylamino)ethyl methacrylate have been prepared by RAFT polymerization, and the surface properties of the block and random copolymers have been examined by contact angle measurement for water and hexadecane. It has been found that the surfaces of the block copolymers simultaneously exhibit excellent anti-fog and oil-repellent properties.
