| 摘 要： | 纳米粒子在聚合物中均匀、稳定分散,是纳米复合材料具有优良性能的前提。文中通过选择表面活性剂改性纳米SiO2,提高纳米粒子在环氧树脂中的分散性,制备出不同含量的n–SiO2/环氧树脂聚合物复合材料,探讨了纳米SiO2对复合材料强度的影响规律。研究结果表明:改性后的纳米SiO2粒子在聚合物体系中呈单分散状态,均匀分布的纳米粒子与基体结合紧密,其在基体中起到了物理交联点的作用,对剪切力的抵抗能力增强,提高了复合材料的综合性能。加入6%质量分数的纳米粒子,复合材料的拉伸剪切强度可提高35.1%。

| Abstract: | To increase the properties of nano-polymer composite,the key job is how to disperse nano-particles equably and steadily.In this paper,modificating n-SiO2 by surface activity agent to disperse nano-particles was studied.The results showed that n-SiO2 particles modificated disperses well in nano-polymer composite,and combined with Epoxy resin matrix closely,enhanced the properties of composite as the role of physical combination spot against the shear strengthens.When the nano particle was adulterated with 6 ... |
