目前研究中采用的是亚硫酸钠还原氧化石墨。聚乙烯醇(PVA)/石墨烯纳米复合材料的制备只需两个简单的步骤:制备PVA/氧化石墨(GO)纳米复合材料薄膜并将其浸泡在还原剂水溶液中。该方法防止了在PVA/GO水溶液中直接还原时GO的团聚现象,为用简单的还原剂放大制备石墨烯纳米复合材料开辟了一条新的途径。仅添加0.7wt%的还原氧化石墨,抗拉强度提高40%,断裂伸长率提高70%。此外,对于含石墨烯的复合材料,还观察到了良好的导电性和所制备薄膜的表面性质的变化。
Sodium hydrosulfite is used to reduce graphite oxide in current study. The preparation of poly (vinyl alcohol) (PVA)/graphene nanocomposites is realized using two simple steps: the synthesis of PVA/graphite oxide (GO) nanocomposites film and immersion of such a film in the reducing agent aqueous solution. This method prohibits the agglomeration of GO during direct reduction in PVA/GO aqueous solution, and opens a new way to scale up the production of graphene nanocomposites using a simple reducing agent. A 40% increase in tensile strength and 70% improvement in elongation at break have been obtained with only the addition of 0.7 wt.% of reduced graphite oxide. Furthermore, a good level of conductivity and a variation in the surface property of the prepared films have been observed for the composites containing graphene.
