摘要:
为提高二氧化钛涂层的防污性能，采用KH-550硅烷改性锐钛矿型TiO2颗粒，并充分分散于二氧化钛凝胶涂层中。通过降解亚甲基蓝溶液、细菌贴附试验、藻类贴附试验，分别评价了涂层的光催化性能、抗菌性能及抗藻类附着性能，并利用激光共聚焦显微镜及扫描电子显微镜对藻类在涂层表面的附着情况进行分析。结果表明，添加TiO2纳米颗粒涂层的防污性能较未添加TiO2纳米颗粒涂层有较大程度的提高。添加粒径为5~10 nm TiO2颗粒的二氧化钛涂层对小球藻、三角褐指藻及小新月菱形藻的附着降低率分别达到了92.1%、71.5%和62.1%，相较于纯二氧化钛涂层对3种藻类的附着降低率分别提高了29.7%、68.4%和43.5%。TiO2颗粒的加入可以有效地提高涂层的光催化性能，光催化使得涂层具有亲水、抗菌及自清洁的性能进而有利于提高涂层的防污性能。

Abstract:
To improve the antifouling performance of the titanium dioxide coating, TiO2 particles were modified with KH-550 silane and dispersed in the titanium dioxide gel coating. The photocatalytic performance, antibacterial properties and anti-algae attachment properties of the coatings were evaluated respectively. The attachment situation of algae on the surface of the coatings was studied by laser scanning confocal microscopy and scanning electron microscopy. The results show that the antifouling performance of the coating added with TiO2 nano-particles is better than that of the coating without adding TiO2 nano-particles. The reduction rates of the titanium dioxide coating added TiO2 particles with the particle size of 5-10 nm for Nitzschia closterium f. minutissima, Phaeodactylum tricornutum and Chlorella adhesion attain 92.1%, 71.5% and 62.1% respectively. Compared with the pure titanium dioxide coating, the reduction rates for three algaes are improved by 29.7%, 68.4% and 43.5%, respectively. The addition of TiO2 particles can make the coating possesses hydrophilic, antibacterial and self-cleaning properties, which are beneficial for improving the antifouling performance of the coating.
