摘要:
在0.2 mol·L氯化胆碱体系下以电化学法剥离石墨箔得到石墨烯,采用高分辨透射电子显微镜、扫描隧道电子显微镜、红外光谱、拉曼光谱等方法研究了所得到的石墨烯的形貌与结构.结果表明:所得的产物最薄仅为2～4层,多数为6～8层,并且具有较好的完整性,无明显团聚与褶皱.与氧化还原法相比结构缺陷及氧化官能团含量明显降低.将石墨烯制成无支撑石墨烯薄膜,测量其导电性可知在其面密度为0.5 mg·cm时其方块电阻仅为19.3 Ω/□,显示出良好的导电性能.
Abstract:
Few layers graphene has been prepared by electrochemical method in the 0.2 mol·L choline chloride solution and a voltage program +5 V,5 s and 0 V,3 s was applied for 720 cycles.High resolution transmission electron microscopy(HRTEM),scanning electron microscope(SEM),infrared spectrum(FT-IR)and Raman spectrum were used to the analysis of the morphology and structure of graphene.The results showed that the thinnest graphene was 2-4 layers,and the majority was 6-8 layers.Free standing graphene film was fabricated to measure its electrical property,and it showed that the squarer resistance only 19.3 Ω/□ with a surface density of 0.5 mg·cm.
