图4 在500℃下煅烧3小时后涂有亚麻油-OSI-TIO2-35复合物与一个TMSS BY11-018-OSI-TIO2-35复合材料表面的水接触角。2和5号表示在样品表面上附加一个2.0-LL水滴后的值

所有的表面是亲水性的,其水接触角是远低于对照煅烧玻璃板的。特别是,煅烧过的亚麻子油的OSI-TIO2-35复合物呈强亲水性。水接触角小雨5°要求实现对所有煅烧亚麻籽油的OSI-TIO2-35复合材料的检验。

500℃中的温度高到足以烧坏亚麻籽油。此外,TMSS BY11-018和OSI-TIO2-35这两种粒子的表面上甲硅烷基团通过煅烧被转化成氧化硅。所有的疏水性基团因而消失,表面被改造到表现出高度的亲水性[23,24]的SiO 2-氧化钛复合膜。

在本研究中开发的有机- 无机杂化复合材料是适合于高疏水性和亲水性高的涂层。此外,该复合材料是无氟的。它们可作为自清洁,防污和防污染涂料。

致谢 我们感谢庆应义塾大学为中心的研究推广的资助计划,为研究人员和格兰在从教育部21世纪COE计划''庆应义塾人寿共轭化学''和文化,体育,科学, 技术上日本对这项工作的支持。
