Description

一种光感应制备仿生疏水层的表面处理方法
技术领域
本发明涉及表面处理技术领域,尤其是指一种光感应制备仿生疏水层的表面处理方法。
背景技术
现有技术中,氟硅类疏水膜制备方法之一是通过浸涂后烘烤的方法制备,该方法的缺点是工艺流程较长,需要消耗较多的氟硅烷原材料,烘烤温度较高,而一般塑胶材料无法耐高温,造成成本较高和影响使用;制备方法之二是使用物理气相沉积(PVD)或化学气相沉积(CVD)的方法制备。物理气相沉积制备疏水涂层的缺点是氟硅烷在沉积过程中没有发生化学反应,所以涂层的结合力不好,耐磨性较差及使用寿命较短。化学气相沉积制备反应气体容易造成氟硅烷的裂解,而影响疏水效果,并且沉积速度较慢成本较高。
氟硅类材料表面处理,其无刻蚀处理得到的疏水疏油层不耐摩擦,防腐蚀效果不好,采用真空PVD,虽然疏水有很好的效果,但存在成本高、工序复杂、耗时长等缺点。
有鉴于此,本发明提出一种克服上述缺陷的光感应制备仿生疏水层的表面处理方法,本案由此产生。

二,在紫外灯下辐射;
三,在常压条件下蒸镀氟硅类聚合物,得到的仿生疏水层。
进一步,步骤一中,基材为塑料、金属、陶瓷或者玻璃中的一种。

进一步,步骤三中,蒸镀氟硅类聚合物为全氟癸基三乙氧基硅烷、全氟癸基三甲氧基硅烷或全氟辛基三乙氧基硅烷中的一种。
进一步,步骤三中,常压条件下蒸镀氟硅类聚合物温度为150-300℃。
进一步,步骤三中,常压条件下蒸镀氟硅类聚合物时间为5-30min。
