1. 研究目的与意义（文献综述）

超疏水材料是一种对水有着排斥作用的材料，通常要求表面接触角大于150°，且滚动角小于10°，具有这种性质的材料能使水滴在其表面轻易的滚落带走灰尘，从而达到自清洁的效果。

超疏水材料具有广泛的应用前景, 近年来已成为材料研究的热点，在自清洁、防腐蚀、防雾、流体减阻等领域有着广泛的潜在应用。

自然界中的荷叶、玫瑰花瓣、壁虎脚等是超疏水材料的典型，为科研人员制备超疏水材料提供了诸多的灵感。

2. 研究的基本内容与方案

本课题研究的基本内容包括：表面粗糙度和表面能大小对于材料疏水性的影响；如何制备出具有光学活性的tio2表面；制备出的超疏水表面与基质间吸附性的研究。

本课题的目标是研究一种制备方法简便的具有光学活性的经久耐用的自清洁超疏水涂层。

本课题拟采用ticl4为原料，经水解法制备不同粒径的tio2纳米粒子，增加材料粗糙度，利用氟硅烷在tio2纳米粒子表面进行接枝，减小材料的表面能。
