The friction behavior of the composite film in sliding against AISI 52100 steel was examined on a DF PM friction coefficient measurement apparatus. The results indicated that the TiO 2 nanolines were dispersed in the poly(butyl acrylate) network. The film exhibites a good antiwear property.展开更多
文摘采用复合法制备了纳米TiO2/丝素复合膜,并用AFM、EDS和IR对复合膜进行了表征,考察了复合膜的光催化甲基橙行为。结果表明,复合膜制备方法合理,当w(TiO2)=0.1%时,它以粒径50 nm左右均匀分散于复合膜中,复合膜与普通丝素膜仅存在细微的构象差异,因纳米TiO2存在,复合膜对甲基橙降解率达91%,催化性能符合Langmu ir-H im shelwood模型。
