摘    要:采用水溶性羟丙基甲基纤维素HPMC对无机纳米ZnO粒子进行物理吸附处理 ,获得了核为无机纳米ZnO ,外壳为水溶性高分子HPMC的粒子。然后在其上进行了甲基丙烯酸甲酯的接枝聚合。采用红外光谱、差热分析的方法对复合粒子进行了表征 ,并采用透射电镜观察了粒子的形貌。红外光谱表明在纳米ZnO的表面吸附了HPMC并接枝了PMMA ,差热分析表明HPMC ,HPMC g PMMA和ZnO/HPMC g PMMA的热稳定性逐渐提高 ,透射电镜观察表明 ,在纳米ZnO的表面粘附了一层聚合物 ,成功地实现了纳米粒子的表面修饰。

关 键 词:羟丙基甲基纤维素  化学修饰  无机-有机复合粒子  接枝聚合

Abstract:After nano particles (ZnO) had been encapsulated by a kind of water soluble cellulose Hydoxyl Propyl Methyl Cellulose(HPMC), then methyl methacrylate was grafted onto the surface of them. Thus the surface of nano ZnO had been successfully modified. FTIR, DTA and TEM were utilized to confirm the results. FTIR shows that HPMC was adsorbed onto the surface of ZnO, and PMMA was also grafted onto its surface, DTA says that the heat stability of HPMC, HPMC g PMMA and ZnO/HPMC g PMMA increased greatly, TEM photo demonstrates that polymer adhered onto the surface of nano ZnO which was encapsulated by a layer of film like polymer.
Keywords:Hydoxyl Propyl Methyl Cellulose  Chemical modificaton  Inorganic organic compound particle  Graft
