摘要: Herein, we report a photoinitiated reversible addition-fragmentation chain transfer (RAFT) dispersion copolymerization of methyl methacrylate (MMA) and methacrylic (MAA) for the preparation highly monodisperse carboxyl-functionalized polymeric microspheres. High rates polymerization were observed, with more than 90% particle yields being achieved within 3 h UV irradiation. Effects reaction parameters (e.g., MAA concentration, RAFT agent photoinitiator solvent composition) studied in detail, microspheres obtained most cases. Finally, silver (Ag) composite prepared by situ reduction AgNO3 using as template. The Ag able to catalyze methylene blue (MB) NaBH4 reductant.
