| 摘 要： | 以硅烷偶联剂KH560(γ-缩水甘油醚氧丙基三甲氧基硅烷)为表面改性剂,对ATO(锑掺杂氧化锡)纳米粉体进行表面接枝改性,制得KH560偶联改性的ATO纳米粉体。采用傅立叶变换红外光谱(FTIR)、热重分析(TG)、粒度分析等手段对其进行了分析和表征,研究了KH560用量、反应温度、反应时间对ATO纳米粉体表面偶联改性的影响。结果表明,在乙醇、水混合溶剂中可以实现KH-560对ATO纳米粉体的偶联改性,当KH560用量为0.4 ml,反应温度为30℃,反应时间为2 h时,ATO粉体表面接枝的KH560接枝率最大,并获得较好的分散性。

| Abstract: | Surface modification of ATO nanopowders was performed using KH560 as the coupling agent. The effects of the amount of KH560, reaction temperature and reaction time on the modification of ATO nanopowders were investigated by FTIR, TG analysis and particle size distribution. The results show that ATO nanopowders were successfully modiifed by KH560 in ethanol-water mixtures. The ATO nanopowders have highest grafting yield and well dispersibility with KH560 of 0.4 ml, reaction temperature of 30℃ and reaction time of 2 h. |
