| 摘 要： | 为了增强无机化合物纳米TiO2的亲油性能，采用钛酸酯偶联剂LICA38对纳米TiO2表面进行预处理，并采用原位聚合工艺制备掺杂纳米Ti02的聚苯乙烯（PS）。采用DCA（dynamic contact angle）、XRD、FTIR、XPS、TEM等现代分析手段，对纳米TiO2预处理效果和掺杂材料的性能进行分析。结果表明，钛酸酯偶联剂在纳米TiO2的表面发生化学吸附，粒子的分散性提高，一定含量纳米TiO2的掺杂有助于提高PS的抗拉强度。

| Abstract: | To enhance oil-solubility of nano-TiO2 ,the surface organic modification of nano-TiO2 particles with LICA38 and the technology of doping nano-TiO2 in polystyrene free-radical polymerization was studied in this paper. DCA, XRD, FTIR, XPS,TEM were used to analyze the specimen. The results showed that chemical adsorp- tion was occurred between LICA38 and the surface of nano-TiO2,and the dispersion of nano-TiO2 were improved. Tensile experiments showed that tensile strength of PS doped nano-TiO2 was higher than pure PS. |
