摘要
通过溶胶凝胶法,在天然埃洛石纳米管(HNTs)外壁负载纳米Ti O2晶粒,有效控制了纳米Ti O2粒子的团聚,获得了HNTs负载Ti O2的杂化材料(Ti O2-HNTs)。扫描式电子显微镜(SEM)与X射线衍射(XRD)分析结果表明,纳米Ti O2粒子成功负载于HNTs表面。分别制备了不同Ti O2-HNTs含量的环氧树脂复合涂层,利用热重分析(TGA)、电化学交流阻抗(EIS)、耐磨性测试等表征了复合涂层的性能。结果表明:环氧树脂复合涂层的耐磨性与耐腐蚀性相比于纯环氧树脂均有一定的提高,当Ti O2-HNTs含量为4%时,复合涂层的综合性能最佳。
TiO2 nanocrystals were adsorbed on the surface of natural halloysite nanotubes （HNTs） by means of sol-gel method to form the TiO2-HNTs composites, which effectively controlled the aggregation of TiO2. The XRD and SEM indicated that TiO2 nanocrystals were successfully adsorbed on the surface of HNTs. The composite epoxy coatings with different con- tent of TiO2-HNTs were prepared. The properties of the composite coatings were evaluated by TGA, EIS and wear resistance test. The results indicated that wear resistance and corrosion re- sistance of the composite coatings were improved, and the comprehensive performance was op- timal when the content of TiOE-HNTs was 4wt.%.
