摘要
将锐钛矿型纳米TiO2粉体分散于乙醇中后,按一定的固体组分含量加入到采用溶胶-凝胶法制备的有机硅/SiO2杂化溶胶中,制备出含不同量TiO2的有机硅/SiO2杂化溶胶,在100℃下烘干12 h得到含TiO2的有机硅/SiO2杂化涂层。红外光谱研究表明杂化材料中Ti原子已接枝到了杂化网络中。对杂化涂层性能测试表明:当TiO2质量分数为1%时涂层有较好的物理和耐蚀性能,并且具有良好的防霉效果。
Silicone/SiO2 hybrid sol with different content of TiO2 were prepared. Then the silicone/SiO2 hybrid coating was obtained by drying the sol for 12 h. The infrared spectrum （FT-IR） showed that the Ti atoms were grafted to the hybrid network. The properties of silicone/SiO2 hybrid coatings with different content of TiO2 were studied. The results showed that the coatings had better physical properties, corrosion resistance and better anti mildew effects when 1% TiO2 was added in the coating.
