Abstract

실란커플링제인 glycidoxypropyl trimethoxysilane(GPTMS)과 methacryloxypropyl trimethoxysilane(MPTMS)을 10:0, 9:1, 7:3, 5:5, 3:7, 0:10의 다양한 몰 비로 혼합한 용액으로부터 sol-gel법을 이용하여 하드 코팅 용액을 제조하였다. 제조된 코팅 용액을 polycarbonate(PC) 시트 위에 스핀 코팅 시키고, 130 ℃에서 3 h 동안 열 경화시켜 하드 코팅 막을 제조 하였다. 이 과정 중 코팅 용액 중의 GPTMS와 MPTMS의 몰 비 변화가 코팅 막의 물성에 미치는 영향을 살펴보았다. GPTMS와 MPTMS가 5:5의 몰 비로 제조된 코팅 용액으로 PC 시트 위에 코팅한 경우가 다른 조건으로 제조된 코팅 용액보다 우수한 연필경도 및 기재와의 부착력을 보였다. 또한 코팅 용액 중의 H2O의 첨가량이 증가할수록 코팅막의 연필경도는 증가하였다.

Hard coating solutions were prepared from glycidoxypropyl trimethoxysilane (GPTMS) and methacryloxypropyl trimethoxysilane (MPTMS) precursors with different molar ratios of 10:0, 9:1, 7:3, 5:5, 3:7, and 0:10, respectively, by the sol-gel method. The polycarbonate (PC) sheets were spin-coated, and cured at 130℃ for 3 h. The effect of the GPTMS:MPTMS molar ratios of the mixture was investigated on the properties of coating films. The highest pencil hardness and adhesion to PC sheets of coating films were found for solution with GPTMS:MPTMS molar ratio of 5:5. Also, the pencil hardness of coating films was increased with increasing the H2O content in the coating solutions.
