摘　　要：以乙醇为溶剂,乙酸锌为前驱物,聚乙烯吡咯烷酮为表面修饰剂,采用溶液化学法,制备了氧化锌纳米粒子。考察反应时间、聚乙烯吡咯烷酮加入量及含水量的影响。通过UV-Vis、FL和TEM等对ZnO纳米粒子进行表征。结果表明,在PVP-乙醇反应体系中加入3 m L浓度33.4 mmol/L乙酸锌水溶液,3 m L水,0.5 g PVP,在80℃反应120 min时,制得氧化锌纳米粒子的效果较好,氧化锌纳米粒子呈规则的球形,具有较好的分散性,粒径约为200 nm,且具有较窄的尺寸分布,证明PVP对ZnO纳米粒子表面具有较好的修饰效果。ZnO nanoparticles have been synthesized by using ethanol as solvent,zinc acetate as precursor and poly（ vinyl pyrrolidone） as polymer stabilizer through wet-chemical route. The influence of reaction time,PVP and water additions on preparation of ZnO nanoparticles were studied. The synthesized ZnO nanoparticles were characterized by UV-Vis,FL and TEM methods. The results show that the synthesized ZnO nanoparticles could give better properties by adding 3 m L zinc acetate aqueous with concentration33. 4 mmol/L,0. 3 m L water,0. 5 g PVP under reaction temperature 80 ℃ and reaction time 120 min respectively in PVP-ethanol reaction system. The size of the synthesized ZnO nanoparticles is about 200 nm with a good dispersion and narrow size distribution. This work demonstrated that poly（ vinyl pyrrolidone）could play a better role in the modification of nano-ZnO surface as polymer stabilizer.
