| Research Abstract |
The synthesis of block copolymers consist of readily degradable polyperoxide and vinyl polymer as a non-degradable polymer was investigated in order to prepare nano-porous thin films and to control surface wettability using the readily degradable nature of polyperoxides. The degradation behavior of the block copolymers was also investigated. First of all, the synthetic route to the degradable block copolymers was established using reversible chain-transfer catalyzed polymerization. As a non-degradable vinyl polymer block, polymethacrylates, polyacrylates, and polystyrene were available. It was revealed that only a polyperoxide block in the degradable block copolymer was degraded upon heating at 110 to 150℃ without any degradation of the vinyl polymer block. The morphology of the degradable block copolymer thin films was investigated. The formation of nano-porous thin films and the changes of the surface wettability and adhesion properties induced by the degradation of polyperoxide block in were also investigated.
