摘　　要：制备了插层率为83.5%的尿素插层高岭土复合物(KU)。用X-射线衍射、红外光谱法和Materials Studio软件表征并模拟了KU的结构,结果表明,高岭土经插层后的片层间距从0.720 nm增大到1.342 nm,插层形态是尿素分子单排插入到高岭土,插层机理是尿素的—NH2与高岭土的硅氧四面体的Si—O之间形成氢键。用熔融加工法制备了尼龙1010/KU纳米复合材料(PKU),研究了KU的增强效果及其含量对PKU力学性能的影响,结果显示随KU含量增加,复合材料的拉伸强度提高,缺口冲击强度降低,断裂伸长率随KU含量增加先提高后降低,在KU质量分数为2%时有最大值。Kaolinite complex（ KU） intercalated with urea to expand its interlayer basal spacing from 0. 720 nm to1. 342 nm with an intercalation ratio of 83. 5% has been prepared. A single layered arrangement of urea molecules into kaolinite due to the formation of hydrogen bonding between —NH2of urea and Si—O of kaolinite was simulated by Materials Studio software and confirmed by XRD and FT-IR measurements. PA1010/ KU nanocomposites（ PKU） were prepared by melt compounding and the effects of KU contents on mechanical properties were studied.The results indicated that the tensile strength of PKU increased and the notched impact strength decreased with increasing KU content and the elongation at break of PKU had a maximum value at 2% mass fraction of KU.
