Abstract
Polymer composites are materials in which various fillers are uniformly dispersed on the basis of organic resin. They have excellent processability and diversity for industrial products. Recently, as carbon nanomaterials are developed, there is a great deal of effort to use them as reinforcing fillers to fabricate high performance composite materials. In order to transfer the inherent properties of fillers into composite materials as much as possible, the good dispersion and orientation of fillers, and favorable interfacial interaction between fillers and matrix are considered to be very important. In this review article, we intent to derive and explain the relationship between surface chemical structure of fillers and physical properties of composites as a strategy of high strength and toughness of graphenebased polyimide composites. 고분자 복합재료는 유기 중합체인 고분자 수지를 기지로 다양한 충전제를 균일하게 분산시킨 소재로서 가공성이 우수하며 제품의 다양성이 많은 특징이 있다. 최근에는 탄소 나노소재들이 개발됨에 따라 이를 보강재로 활용하여 보다 우수한 복합재료를 개발하기 위한 많은 노력이 있다. 보강재 본래의 특성을 최대한 복합재료로 전환시키기 위해서는 이들의 분산, 배향 및 계면특성이 매우 중요하게 여겨진다. 본 총설 논문에서는 그래핀 기 반 폴리이미드 복합재료의 고강도화 및 고인성화 기술 전략으로써 그래핀 기능화에 의한 표면 화학구조와 물성간 상관관계를 도출하고 설명하고자 한다.
