| 摘 要： | 用ｓｏｌ－ｇｅｌ法在聚碳酸酯ＰＣ上制备一层耐磨涂层。该涂层为有机－无机复合网络，由γ—缩水甘油醚氧丙基三甲氧基硅烷（γ—ＧＰＴＭＳ）和金属醇盐Ｔｉ（ＯＣ２Ｈ５）４合成。采用浸涂工艺，热固化后可得到几微米厚的透明涂层。用３—氨丙基三乙氧基硅烷（３—ＡＰＳ）对ＰＣ表面进行处理，可使涂层与基体的结合力大大提高。涂层的基本骨架由Ｓｉ－Ｏ－Ｔｉ组成，能显著改善ＰＣ材料的耐磨性能。

| Abstract: | Novel abrasion resistant coating materials prepared by the sol-gel method have been developed and applied on the polymeric substrate polycarbonate.This coating is inorganic/organic hybrid network material synthesized from -glycidoxypropyltrimethoxysilane (-GPTMS) and metal alkoxide Ti(OC2H5)4.The adhesion between coating and substrate can be greatly improved by treating the polymeric substrate surface with a primer solution of ethanol containing 3aminopropyltriethoxysilane (3APS).The basic structure of this coating is Si-O-Si and it can improve the abrasion resistance of the polymeric substrate polycarbonate significantly. |
