| 摘 要： | 采用硅烷偶联剂对纳米掺锑二氧化锡(ATO)粒子表面进行化学改性,以分散剂对其进行物理包覆,调节分散工艺、体系黏度和pH,获得了稳定性可达到两个月以上的水性纳米ATO浆料.傅立叶红外光谱分析表明,硅烷偶联剂可以有效地包裹在纳米粒子表面.当采用硅烷偶联剂KH570,其用量为纳米ATO粒子质量的1.5%时,包覆效果最好;选用嵌段型分散剂3275,其用量为体系质量的0.2%时,分散效果最好;当体系黏度大于88 mPa·s和pH=10时,浆料稳定性最好.透射电子显微镜观测表明,纳米ATO粒子获得了良好分散.

| Abstract: | A waterborne nano-ATO slurry with a stability for more than 2 months was developed by using silane coupling agent to chemically modify and dispersant to physically cover the surface of nano-ATO in combination with adjusting dispersion process, viscosity and pH value of the slurry. FTIR analysis showed that silane coupling agent can be connected to the surface of nano-ATO. The optimal coverage effect was obtained when silane coupling agent KH570 was adopted with a dosage of 1.5% of the mass of nano-ATO, and ... |
