液相剥离石墨制备石墨烯

Preparation of graphene by liquid-phase exfoliation graphite

石墨烯具有独特的性质和广泛的潜在应用前景,近年来受到广泛的关注。石墨烯材料的制备是研究其性能和探索其应用的前提和基础。液相剥离石墨是一种最可能批量生产石墨烯的方法之一。我们介绍了当前从以原始的石墨为原料直接液相剥离制备石墨烯的发展现状和存在的问题。我们重点讨论有机溶剂辅助剥离和表面活性剂辅助剥离两个比较成熟的液相剥离方法的研究进展,为宏量可控制备高质量石墨烯提供参考。

Graphene with unique properties and wide potential applications has received considerable attention in recent years.Material preparation is the study of its performance and to explore its application premise and foundation.Liquid-phase exfoliation graphite is one of the most potentially up-scalable motheds for the bulk production of graphene.Here,we introduce the current development present situation and the existing problems of preparation of grapheme by directly liquid-phase exfoliation of original graphite.Particularly,we focus on or-ganic solvents assisted exfoliation and surfactant assisted exfoliation two maj or classes successful liquid-phase exfoliation methods,to provide references for the successful production of high quality graphene by means of liquid-phase exfoliation of graphite.
