大功率超声设备制备石墨烯

Preparation of Graphene by High Power Ultrasonic Equipment

近年来,因石墨烯独特的六元环结构和优异的性能,在诸多方面都有应用,引起了各个行业的广泛关注。目前,在制备石墨烯方面,人们已经取得了不错的进步。过去人们通常使用机械剥离法,化学气相沉积法、外延生长法等方法来制备石墨烯,但这些方法都有各自的优缺点。超声波声化学设备制备利用的是超声波的空化效应,通过超声物理剥离石墨烯,具有低成本,且保持结构完整的特性。在近期研究进展的基础上,综合分析了目前主流石墨烯制备方法的优缺点,主要阐述了液相剥离法的剥离机理,以及超声波声化学设备工作原理,加深了对剥离机理的了解。利用XPS、SEM、TEM等技术对石墨烯样品的结构、形貌进行了分析,对制备高品质石墨烯具有指导意义。
