%X 采用聚二甲基二烯丙基氯化铵（PDDA）对二氧化硅进行表面改性，制备改性二氧化硅/NR纳米复合材料，并对其微观结构和物理性能进行研究。结果表明，改性二氧化硅均匀分散在天然胶乳基体中；扫描电子显微镜分析显示复合材料呈界面模糊的海岛结构；改性二氧化硅/NR纳米复合材料的物理性能较NR胶料大幅提高；随着改性二氧化硅用量的增大，改性二氧化硅/NR纳米复合材料的物理性能先提高后降低；当改性二氧化硅的用量为5.3份时，纳米复合材料的综合物理性能较好。;The surface of silica was  modified by polydimethyl diallylammonium chloride，and the modified silica/NR nanocomposite was prepared，and its microstructure and physical properties were investigated.The results showed that modified silica was uniformly dispersed in nature rubber latex；it was found by SEM that there was sea-island structure without clear phase boundary in silica/NR nanocomposite；compared with NR compound，the physical properties of modified silica/NR nanocomposite increased significantly；as the addition level of  modified silica increased，the physical properties of modified silica/NR nanocomposite increased first and then decreased；when the addition level of  modified silica was 5.3 phr，the composite possessed better comprehensive physical properties
