| 摘 要： | 以天然蒙脱土为原料，11-氨基酸作为有机插层剂与蒙脱土层间的阳离子进行交换制备OMMT，用原位聚合法制备PA6／OMMT／SiO2纳米复合材料，用X射线衍射仪、FT-IR光谱仪、差示扫描量热仪等对OMMT、纳米复合材料的结构及力学性能进行表征。结果发现，添加3％（质量含量，下同）OMMT的PA6／OMMT复合材料的拉伸强度、弯曲强度和弯曲模量较纯PA6分别提高了19％、13．8％、14％；而纳米SiO2的加入使纳米复合材料的拉伸和弯曲强度、刚性和韧性得到提高的同时，明显改善了蒙脱土使纳米复合材料缺口冲击强度下降的趋势，当纳米SiO2含量为1％时，缺口冲击强度提高了近33．5％。

| Abstract: | An organic MMT was prepared from natural MMT by cation exchange with amino acid. PA6/OMMT/SiO2 nanocomposites were prepared via in-situ polymerization. Their structure and mechanical properties were characterized using FT-IR, XRD, and DSC, etc. Compared with neat PA6, the tensile strength, flexural strength, and flexural modulus of PA6/OMMT were 19 %, 13.8 %, and 14 % higher, respectively, when OMMT was 3 %. The introduction of nano-SiO2 further improved the mechanical properties, especially the impact strength was increased by 33.5 % at 1 wt% loading of nano-SiO2. |
