Abstract
Graphene is a 2D form of carbon. Due to its wonderful physical and chemical properties has attracted wide interest in recent years. Graphene majorly made by two completely different approches i.e. top-down and bottom up. The top-down approach depends on exfoliation of carbon to provide graphene. Liquid phase exfoliation is more classified in to primarily two categories one is surfactant free and another is surfactant aided Liquid part exfoliation. In this paper we have reportable the liquid phase exfoliation of surfactant aided graphene via probe tip sonication followed by centrifugation. The yield of graphene obtained has been exaggerated and it is easy technique to provide films and graphene composites for photovoltaic applications.
