尼龙1010/十八烷基胺插层蒙脱土纳米复合材料研究

Study of Nylon 1010/Octadecylamine Intercalated Montmorillonite Nanocomposites

通过熔融加工制备了尼龙1010(PA1010)/十八烷基胺插层蒙脱土(OMMT)纳米复合材料。研究了OMMT含量对PA1010/OMMT纳米复合材料力学性能的影响。当OMMT质量分数为2%时,该纳米复合材料的综合力学性能达到最优。用TG、DMTA、DSC等分析方法对材料的热稳定性、结晶性能等进行了分析表征。结果表明,OMMT的加入提高了纳米复合材料的结晶温度、玻璃化转变温度和储能模量,但纳米复合材料的热稳定性稍有降低。

PA1010/octadecylamine intercalated montmorillonite （ OMMT ） nanocomposites were prepared by melt processing. The effect of content of OMMT on mechanical properties of the PA1010/OMMT nanocomposites was studied. The experimental results showed that when the content of OMMT was 2 wt% , the overall mechanical properties of the nanocomposite were the best. The thermal stability, crystallization of the nanocomposites were characterized by TG, DSC and DMTA. By addition of the OMMT, the thermal stability of the nanocomposites decreased a little, while the crystallization temperature, the glass transition temperature and the storage modulus of the nanocomposites were correspondingly increased.
