摘　　要：采用沉淀法制备出Co3O4的前驱体,研究了PEG的加入量对体系表面张力系数的影响;采用SEM和粒度分析仪等手段分析了表面活性剂PEG的加入量对Co3O4的前驱体形貌和粒度的影响。试验结果表明,当PEG的加入量为0.8%(质量分数,下同)时,溶液体系表面张力系数最小,可以获得分散性良好、中位粒径为0.1μm的前驱体颗粒。The precipitation method to prepare precursor of Co3O4 was adopted in this paper.The influence of the addition amount of surfactant PEG on the system surface tension was studied.The effect of addition amount of surfactant on the precursor was analyzed by the means of SEM and laser particle size analyzer.The result indicates that the solution system surface tension is smallest when the amount of PEG is 0.8wt% while the precursor may be dispersed well.
