| 摘 要： | 以石墨氧化物为前躯体,采用爆炸法合成石墨烯.利用XRD,SEM,XPS,TEM,SAED和Raman等测试手段对石墨烯的形貌,成份和结构进行表征.结果表明,石墨氧化物在爆炸产生的热量和冲击波的作用下发生完全剥离并被还原成石墨烯.新合成的石墨烯呈透明褶皱状,含有2层～5层石墨层,并具有较好的晶体结构.Abstract：Graphene nanosheets were synthesized using graphite oxide as a precursor by detonation. The composition,and structure of graphene nanosheets were characterized by X-ray diffraction,X-ray photoelectron spectroscopy,scanning and transmission electron microscopy,selected area electron diffraction,and Raman spectroscopy. Results indicated that the as-prepared material was transparent and wrinkled,and comprised 2-5 graphenes with a highly crystalline structrue. The exfoliation and reduction of graphite oxide to graphene nanosheets was induced by the self-generated thermal energy and shockwave of detonation.
