摘　　要：氧化石墨是石墨在强酸体系中加入高锰酸钾等强氧化剂后形成的一种层间化合物,是石墨制备石墨烯的中间产物。本文采用Hummer法制备氧化石墨,氧化石墨制得以后离心并洗至中性,干燥后将其配成浓度较低的溶液,分别进行不同时间的超声处理。采用XRD、激光粒度及电位分析仪、紫外分光光度计以及红外光谱仪对超声不同时间的氧化石墨进行分析,从而得出反应时间对Hummer法制备氧化石墨的影响。Graphite Oxide is a kind of intercalation compound that formed in the strong acid system joined by the oxidants such aspotassium permanganate, and it is the intermediate of preparing Graphene. In this paper,Graphite Oxide （GO） was prepared bythe Hummer method. The prepared GO was centrifuged and washed to the neutral,and then was made up to the solution of lowconcentration and treated by ultrasonic with different time. To investigate the effect of ultrasonic time on the properties of GO, thesamples were examined by XRD, Particle Size Analyzer, Ultraviolet Spectrophotometer and Infrared Spectroscopy.
