摘　　要：以氢氧化铜为前驱体,在超声和微波作用下制备纳米氧化铜。借助透射电镜(TEM)、X射线衍射(XRD)、粒度分析等手段,研究了超声、分散剂、微波等制备条件的影响。结果表明:采用该法可以制备粒径小(15 nm)、分散良好的纳米氧化铜粉体;超声可使前驱体Cu(OH)_2转变为CuO,并粉碎颗粒间形成的团聚:分散剂通过表面修饰抑制颗粒的团聚:微波加热促进了前驱体的转化,并抑制颗粒的长大。Using Cu（OH）2 as precursor, CuO nanoparticles were prepared under ultrasonic and microwave irradiation. The influences of ultrasonic vibration, dispersant and microwave irradiation were studied by using TEM, XRD and particle size analyzer. The results show that CuO nanoparticles with size of 15nm and good dispersibility are synthesized via the novel method mentioned above. Ultrasonic vibration is helpful to the transformation of Cu（OH）2 into CuO and the disruption of agglomeration. The dispersant restrains the aggregation of nanoparticles by the surface modification. Microwave irradiation promotes the transformation of Cu（OH）2 to CuO and restrains the growth of nanoparticles.
