摘　　要：氧化石墨烯是近几年国内外研究的热点之一。其原料易得、成本低廉、且具有良好的物理和化学性能,是一种优良的复合材料填充剂。本文首选改进的Hummers法制备氧化石墨烯,利用超声分散法制备了聚乙烯醇/氧化石墨烯纳米复合材料,使用红外光谱、扫描电镜等手段对其进行表征。结果显示,超声分散法使氧化石墨烯均匀的分散在聚乙烯醇基体中形成层离型复合材料。该方法可以用于多种水溶性聚合物。Graphene oxide was one of the hottest inorganic layer materials recently, which had the characteristics of low - cost, easy got and many excellent physical and chemical properties to be an excellent filler of nano - composite ma- terials. The graphene oxide was prepared by modified Hummers＇ method, and the polyvinyl alcohol/graphene oxide nano- composite was prepared by ultrasonic dispersion method. Composite superficial morphology and microstructure were char- acterized by FT - IR, XRD, and SEM. The result showed that graphene oxide nano - sheets dispersed in the polymer uni- formly. This method can be used for a variety of water - soluble synthetic polymer.
