纳米氢氧化铝的表面改性研究

Surface modification of nanosized aluminium trihydrate

介绍了纳米氢氧化铝的表面改性过程及多种因素的影响。应用表面改性剂进行了氢氧化铝表面改性研究 ,采用了比表面积测定、红外光谱分析等测试方法对改性效果进行评价 ,确定了最佳改性条件。检测了改性的氢氧化铝粉体。研究结果表明 ,氢氧化铝颗粒比表面积增大、吸油值降低。

The process of surface modification of ATH and various factors effecting the process were described. The surface modification results were analysed by the methods of the specific surface area measurement and infra red absorption spectroscopy, and the best conditions for modification were obtained. The results indicate that the modified ATH has a larger specific surface area and lower DBP absorbency with chemical and physical adsorption behaviours.
