摘要: 将环氧树脂(EP)与正硅酸乙酯(TEOS)反应生成的改性前驱体进行水解,然后将水解液与熔融已内酰胺混匀,通过原位聚合法制备出新型尼龙6(PA6)/EP/SiO₂纳米复合材料。用付立叶变换红外光谱(FT-IR)、机械性能测试、热重(TGA)分析、动态力学分析(DMTA)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和原子力显微镜(AFM)等测试技术对材料进行了结构分析和表征。结果表明,SiO₂粒子在基体材料中分散均匀,粒径约30 nm;复合材料的力学性能随SiO₂加入量的增加呈现先上升后下降的趋势,当SiO₂加入质量分数为3%时,复合材料的综合力学性能最优,其拉伸强度、冲击弯曲强度及断裂伸长率分别较纯PA6提高了28%、360%、43%和45%。

Abstract: Novel PA6/epoxy resin(EP)/SiO₂ nanocomposites were prepared by mixing caprolactam with hydrolysis solution of modified precursor,which was synthesized by tetraethoxysilane(TEOS) and epoxy resin,via in situ polymerization.The structure and properties of the nanocomposites were investigated by fourier transform infrared spectroscopy(FTIR),mechanical tests,dynamic mechanical analysis(DMTA),scanning electron microscopy(SEM),transmission electron microscopy(TEM),atomic force microscopy(AFM) and thermal gravimetric analysis(TGA),etc.The results show that silica particles were homogeneously dispersed in the material matrix.The diameter of nano-silica is about 30 nm.The mechanical properties show a tendency to increase and then decrease with the increase of the silica content and have maximum values at 3% silica content.Compared with those of pure PA6,the tensile strength,impact strength,flexural strength and elongation at break of PA6/EP/silica nanocomposites were improved by about 28%,360%,43% and 45%,respectively.
