摘　　要：选用钛酸酯偶联剂对纳米氢氧化铝(nano-ATH)进行表面改性,以改善其在聚丙烯(PP)中的分散性。利用透射电镜(TEM)表征了nano-ATH的改性效果;研究了改性条件对nano-ATH/PP复合材料性能的影响。结果表明,在偶联剂质量分数为2.0%,改性时间为20min,改性温度为85℃的条件下,nano-ATH/PP复合材料的综合性能较好。改性后nano-ATH的分散性得以有效的改善。Nano-ATH was surface modified by titanate coupling agent in order to improve its dispersion in PP.The modified effect of nano-ATH was analyzed by TEM,and the effects of modification conditions on property of nano-ATH/PP composite were studied.The results showed that the comprehensive property of nano-ATH/PP composite was better when nano-ATH was modified by 2.0 wt% coupling agent for 20 min at 85 ℃.The dispersion of modified nano-ATH was improved greatly.
