초록
고분자 복합재료는 높은 기계적 물성을 요구하는 산업용 소재로 널리 사용되고 있다. 이러한 고분자 복합재료에 사용되는 유리섬유나 무기충전제는 불균일한 분산 및 고분자와 충전제 간의 계면 접착력 저하에 의해 강도 저하와 같은 문제점이 상존한다. 본 연구에서는 열분해 반응을 통해 제조되는 비극성 폴리에틸렌 왁스에 대해 열분해 반응과 함께 연속적으로 극성 아크릴산 단량체를 그래프트 반응시켜 극성개질의 효율을 향상시킨 아크릴산 변성 폴리에틸렌 왁스를 합성하여, 이를 폴리아미드 매트릭스와 무기충전제인 유리섬유의 고분자 복합재료에 적용하여 폴리아미드 기반고분자 복합재료의 물성에 미치는 영향을 조사하였다.
Polymer composites are widely used as industrial materials requiring high mechanical properties. Glass fibers and fillers, which are used as a reinforcement in composites, usually have some problems such as nonuniform dispersion and poor interfacial adhesion. In this study, an acrylic acid-modified polyethylene wax was synthesized by the sequential reaction of pyrolysis of polyethylene followed by grafting with a polar acrylic acid. The acrylic acid-modified polyethylene wax was applied to polymer composites of the polyamide matrix and glass fiber reinforcement. The effect of acrylic acid-modified polyethylene wax on physical properties of polyamide based composites was thoroughly investigated.
