石墨烯之制备方法;PREPARATION METHOD OF GRAPHENE

摘要

本文中所揭露者为一种石墨烯之制备方法，其藉由简化方法能够制备具有较小厚度和大面积且具有减少的缺陷产生之石墨烯。石墨烯之制备方法包括：形成包括碳基底材料和分散剂之分散液，该碳基底材料包括未氧化石墨；及将分散液连续通过高压均质机，该高压均质机包括入口、出口和在入口和出口之间用于连接的具有微米级直径之微通道，其中当该碳基底材料在施加剪力下通过微通道时，该材料被剥离，从而形成具有奈米级厚度之石墨烯。; and continuously passing the dispersion through a high pressure homogenizer including an inlet, an outlet, and a micro-channel for connection between the inlet and the outlet, having a diameter in a micrometer scale, wherein the carbon-based material is stripped, as the material is passed through the micro-channel under application of a shear force, thereby forming graphene having a thickness in nanoscale.
