摘　　要：探讨了KH570在纳米ZnO/CeO2复合粉体上的接枝机理,用FT-IR和XRD等仪器对接枝情况进行了表征,研究了反应时间、超声波时间、偶联剂的用量对接枝率的影响。结果表明:KH570对纳米ZnO/CeO2颗粒进行表面修饰后的粉体,可以均匀地分布在无水乙醇的溶剂中,使溶剂的紫外吸收能力增强,这也说明修饰后的ZnO/CeO2颗粒亲油化度增强,在锦纶6高温熔融纺丝时,可以均匀分散在纺丝液中。当反应时间为2h,超声波振动30min,偶联剂与颗粒质量之比为0.3时接枝率最高。The grafting mechanism of KH570 in the ZnO/CeO2 nanocomposite powder homemade is discussed.The influences of the reaction time,ultrasonic time,amount of coupling agent on the grafting ratio were researched based on graft situation characterized with FT-IR and XRD devices.The research showed that,the ZnO/CeO2 can be distributed evenly in the anhydrous ethanol after be grafted with KH570.As a result,the performance of anti-UV and the lipophilic degree of modified nanometer ZnO/CeO2 enhanced.The modified nanometer ZnO/CeO2 distributed evenly in spinning solution while the spinning melted with NYLON 6 in high-temperature furnace.When the reaction time was 2 hours,the ultrasonic time was 30 min,the mass ratio of coupling agents and nanoparticle was 0.3,the grafting ratio reached the maximum.
