| 摘 要： | 通过原位聚合将甲基丙烯酸甲酯（MMA）接枝于纳米ZnO表面，制备了PMMA接枝纳米ZnO复合粒子，将其加入聚氯乙烯（PVC） 基体中进行改性。研究了纳米ZnO粒子在PVC基体中的分散性和PVC复合材料的力学性能，探讨了改性纳米ZnO粒子填充PVC材料的抗紫外线性能。结果表明，改性后的纳米ZnO粒子在PVC基体中分散均匀, 提高了纳米ZnO粒子与PVC基体之间的相容性，使改性PVC材料的拉伸强度达到78 MPa，比纯纳米ZnO粒子改性PVC提高了35 %；冲击强度提高了近1倍，达到13.6 kJ/m2；加入改性纳米ZnO粒子的PVC还具有明显的吸收紫外线功能。

| Abstract: | ZnO nanoparticles were in-situ grafted with PMMA from the surface and used as a modifier for PVC.Such ZnO nanoparticles were homogeneously dispersed in the PVC matrix.Filled with PMMA grafted ZnO nanoparticles,PVC composites possessed a tensile strength of 78 MPa,which was 35% higher than that based on untreated ZnO;and an impact strength 13.6 kJ/m~2,twice as untreated case.In addition,PMMA grafted ZnO nanoparticles imparted PVC a perfect UV-shielding property. |
