| 摘 要： | 使用硅烷偶联剂3–氨基丙基三乙氧基硅烷(APTES)对纳米TiO_2进行包覆,得到TiO_2-g-APTES,再通过CuBr和N,N,N',N',N'–五甲基二乙烯基三胺(PMDETA)组成的催化体系,在纳米TiO_2表面进行原子转移自由基聚合反应(ATRP)接枝聚丙烯腈(PAN),再与聚丙烯(PP)共混制得复合材料。通过傅立叶变换红外光谱分析、热失重分析、凝胶渗透色谱和透射电镜表征,结果证明成功得到分子量可控和分子量分布较窄的TiO_2-g-PAN。添加了TiO_2-g-PAN的PP复合材料的力学性能及抗老化性都得到了提高。

| Abstract: | Nano-titania was coated with silane coupling agent 3-aminopropyltriethoxysilane (APTES) to obtain TiO2-g-APTES,CuBr and N,N,N",N",N"-pentamethyldiethylenetriamine (PMDETA) on the surface ofnano titania were studied by atom transfer radical polymerization (ATRP) grafted polyacrylonitrile (PAN),and blended with PP to obtain the composite material.TiO2-g-PAN was obtained by Fourier transform infrared spectroscopy,thermogravimetric analysis,gel permeation chromatography and transmission electron microscopy.The results show that TiO2-g-PAN with narrow molecular weight and controlled molecular weight is successfully obtained.It improves the anti-aging and mechanical properties of PP composites. |
