| 摘 要： | 通过酰氯化法制备了有饥化的纳米SiO2，用熔融共混法制备了尼龙6／有机化纳米SiO2复合材料，研究了复合材料的力学性能和结晶形态。研究表明：有机化纳米SiO2的加入能够提高尼龙6的拉伸强度和冲击强度，改性效果明显好于未经表面处理的纳米SiO2；偏光显微镜照片显示，有机化纳米SiO2的加入起到了异相成核的作用，使尼龙6的结晶形态发生了改变，由大的球晶变为细小的晶粒。

| Abstract: | Nano-meter organo-SiO2 was prepared by means of acyl-chloridate methods. Nylon 6/nano-meter organo-SiO2 composites with different contents of nano-meter organ-SiO2 were prepared by melt blending, and the mechanical properties and crystallization morphology of the composites were studied. The results showed the addi- tion of the nano-meter organo-SiO2 could improve the impact strength and tensile strength of the nylon 6. The modi- fied effect of the nano-meter organo-SiO2on nylon 6 was better than that by neat nano-SiO2 obviously. The results of PLM micrograph showed the nano-meter organo-SiO2 had a heterogeneous nucleation effect on the crystallization, decreased the crystal size of nylon 6. |
