碩士 === 嘉南藥理科技大學 === 化妝品科技研究所 === 98 === In this study, the dense Poly(Methyl methacrylate-Methylacrylic acid)/ Poly(N-Isopropylacrylamide-Methylacrylic acid) [Poly(MMA-MAA)/Poly(NIPAAm-MAA)] core-shell latex particles were synthesized by the method of sopaless seeded emulsion polymerization. Then the core shell latex particles were treated by the ammonia to form the Poly(NIPAAm-MAA) hollow latex. The gold nanoparticles (Au NP) were produced by the method of condensation, and then were adsorbed on the surface of Poly(MMA-MAA)/Poly(NIPAAm-MAA) latex particles and hollow Poly(NIPAAm-MAA) latex particles to form the polymer/Au composite particles. These composite particles were used as carriers to load with Arbutin. The behavior of control release of polymer carriers was investigated. Besides, the Au NP was wrapped in the dense Poly(MMA-MAA)/Poly(NIPAAm-MAA) latex particles and hollow Poly(NIPAAm-MAA) latex particles respectively to form the polymer/Au composite particles. The morphologies and properties of the composite particles were investigated
