그래핀 표면 기능화와 이를 이용한 폴리이미드, 폴리아믹산 하이브리드 물질 합성 및 특성 평가

Abstract

In this study, Forming of organic - inorganic hybrid material experiment was carried out. First, surface functionalized graphene was synthesized through the graphene oxide surface reduction. Imide moieties were attached to amine - surface functionalized graphene using a step-by-step condensation and thermal imidization method. Second, transparent Polyimide (PI), Polyamic Acid (PAA) was prepared by a step growth polymerization of diamine monomer and dianhydride monomer. Finally, each obtained material was mixed together by using organic solvent. The solution was then spin-coated on a cleaned glass substrate and totally organic - inorganic hybrid material layer was successfully casted.
