친수성 코팅 필름의 제조시 코팅막 특성에 미치는 APS(aminopropyltriethoxysilane) 첨가의 효과
Effects of APS(aminopropyltriethoxysilane) Addition on the Properties of Hydrophilic Coating Films
고분자 필름에 대한 우수한 친수성을 보이는 무기-유기 혼성 코팅 용액을 sol-gel법으로 합성하였다. 코팅 용액은 무기물인 콜로이드 실리카 용액(Ludox)에 유기 조성을 함유한 화합물인 APS(3-aminopropyltriethoxysilane)를 첨가하여 제조하였다. 제조된 무기-유기 혼성 코팅 용액을 PET필름 위에 담금코팅 후 형성된 코팅층은 혼성용액 중의 APS의 함유량이 증가할수록 두꺼운 두께를 나타냈다. 또한 코팅용액을 80 ℃로 건조하여 건조 분말을 제조한 후, 코팅용액의 합성조건이 분말의 특성에 미치는 영향을 살펴보았다. 코팅용액 합성시의 용액의 pH는 건조 분말 기공의 크기에 큰 영향을 미치지 못했으나, 용액 중의 APS 첨가량이 증가할수록 기공의 평균 크기는 증가하였다.
Inorganic-organic hybrid coating solutions with a good hydrophilic property on polymeric films were synthesized by the sol-gel method. The coating solutions were prepared by adding 3-aminopropyltriethoxysilane (APS) to a colloidal silica solution (Ludox). The coating thickness on PET sheet, dip-coated with the hybrid solutions, increased with increasing the APS content of the coating solutions. And the effect of synthesis parameters of the coating solutions was investigated on the property of the dried powders, which were prepared by drying the coating solutions at 80 ℃. The average pore diameter of the dried powders, as determined by nitrogen adsorption, increased with increasing the APS content of the coating solutions, while it was not dependent on the pH condition of the coating solutions.
