Abstract

Hard coatings were deposited on a polycarbonate plate as potential substitutes for glass in cars. In this research polyphenylene derivatives were synthesized and the coatings were conducted on a polycarbonate plate. Poly(benzoylphenylene) and its phenylene copolymers were synthesized. Using poly (benzoylphenylene), the coating showed 1H class of pencil hardness. And using its copolymers, the coating showed 2H class of pencil hardness. The copolymer also showed the better abrasion resistance than homopoly (benzoylphenylene).

자동차의 유리를 폴리카보네이트로 대체하기 위하여 폴리카보네이트 판 위에 하드 코팅을 시도하였다. 본 연구에서는 polyphenylene 유도체들을 합성하여 이것들을 이용하여 폴리카보네이트 판 위에 코팅을 시도하였다. 합성한 polyphenylene 유도체는 poly(benzoylphenylene)과 그의 phenylene 공합체들이다. Poly (benzoylphenylene)을 이용한 코팅은 최고 연필 경도 1H를 나타내었으며, 이것의 공중합체를 이용한 코팅에서는 최고 연필 경도 2H를 나타내었다. 내마모성도 공중합체가 더 우수한 결과를 보여 주었다.
