| 摘 要： | 为了解纳米CuO在水介质中分散性能,以纳米材料常用的十二烷基苯磺酸钠、十六烷基三甲基溴化铵和聚乙二醇为分散剂,采用磁力搅拌和超声振荡与添加分散剂相结合的方法制备纳米CuO悬浮液,研究了磁力搅拌和超声振荡以及分散剂型与剂量对纳米CuO悬浮液分散性能的影响。结果表明:磁力搅拌和超声振荡对于纳米CuO粒子在水介质中的分散具有一定的效果,但不能明显提高悬浮液的分散稳定性,而添加一定剂量的分散剂对悬浮液的分散稳定性起着至关重要的作用。磁力搅拌30 min和超声振荡60 min与添加质量分数为0.05%的十六烷基三甲基溴化铵,对0.2%的纳米CuO悬浮液的分散稳定性效果最好。

| Abstract: | To understand the Nano-CuO dispersant performance in aqueous medium, sodium dode- cyl benzene sulfonate, cetyl trimethyl ammonium bromide and polyethylene glycol are commonly used as Nano-materials dispersant. Using magnetic stirring and ultrasonic vibration combining dis- persant prepared Nano-CuO suspensions, their effects on the Nano-CuO suspension performance are studied. The results showed that magnetic stirring and ultrasonic vibration have a certain effect on Nano-CuO in the aqueous dispersion medium, but can＇ t significantly improve the dispersion stability of the suspension, and adding a dose of dispersing agent plays crucial role on the dispersion stability of the suspension. Magnetic stirring 30 min, ultrasonic vibration for 60 min and the mass fraction of 0.05% of cetyl trimethyl ammonium bromide, for a 0.2% suspension of Nano-CuO have the best dispersion stability. |
