블록공중합체 마이셀을 이용한 에너지 포획형 나노구조의 형성과 촉매 응용

Abstract

In selective solvent, diblock copolymers self-associate into spherical micelles consisting of soluble coronas and insoluble cores. Since the chemical properties of core and corona are different from each other, they can be functionalized as different particles. In this study, we synthesize two different metal nanoparticles in PS-PAA micelles to form heterogenous nanoparticle assembly. In particular, we tried to separated gold nanoparticle and silver nanoparticle in different domains to combined both plasmonic and catalitic properties .Catalytic of formed self assembly micelle is evaluated by 4-nitrophenol reduction.
