Influences of TiO2 Micro/Nanopowders on Hydrophobic Property of Nanocomposite Coatings

通过纳米粉体形貌的变化来改变涂层的微结构,进而调控涂层的憎水性.以不同形貌的二氧化钛纳米粉体为填料,以氟硅烷为涂料基料,用浸渍法和旋涂法在铜基材表面制备憎水涂层.利用扫描电子显微镜对纳米粒子和涂层的形貌进行了表征,并对涂层的静态憎水角进行了测量和分析.研究了纳米粒子的形貌、浸渍时间及涂层涂覆层数等条件对涂层憎水性的影响.研究结果表明延长浸渍时间和增加涂覆层数可以增大涂层的致密度,进而增大涂层的憎水性,利用旋涂法制备的纳米粉体复合涂层的静态接触角可达到158°.
