摘要
天然石墨在浓硫酸中用高锰酸钾氧化成氧化石墨(GO),在含有氧化石墨的苯乙烯乳液中进行自由基聚合,可以得到层间插入聚苯乙烯(PS)的石墨纳米复合材料。研究发现,在聚合过程中不仅发生了苯乙烯均聚反应,而且存在插入聚合反应,并用FTIR、XRD、TEM等手段进行表征。
A new polystyrene-intercalatedgraphite oxide/polystyrene nano-eomposite was prepared by emulsion polymerization of styrene in the presence of graphite oxide. Graphite oxide （GO） was synthesized by the oxidization of natural graphite powder with KMnO4 in the concentrated sulfuric acid. The functional groups and the microstructure of the oxidized graphite, and the nano-composite were carefully characterized using various techniques,including FTIR,XRD,TEM and element analysis.
