摘要/Abstract

摘要： 以天然鳞片石墨为原料, 采用Hummers法先制备出石墨氧化物, 再采用微波辐照法在N-甲基吡咯烷酮(NMP)溶剂中合成出石墨烯. 微波辐照选择性地加热NMP溶剂, 同时石墨氧化物因其含氧官能团分解成CO、CO₂、H₂O气体而得以剥离和还原. 通过XRD、SEM、EDS、TEM、HRTEM、SAED、XPS和Raman测试手段对所合成的石墨烯进行了表征. 结果表明, 所合成的石墨烯尺寸为几微米, 呈透明绢丝状结构, 每个石墨烯片含有2~5层石墨层; 所合成的石墨烯可以均匀地分散在NMP溶剂中.

Abstract: Graphite oxide was synthesized with Hummers method using natural flake graphite as carbon source, and then graphene was prepared through microwave irradiation in N-methyl-2-pyrrolidinone (NMP) solvent. NMP solvent was heated selectively during the microwave irradiation process, meantime, the oxygen containing groups of graphite oxide were decomposed into CO, CO₂ and H₂O gases, resulting in the exfoliation and reduction of graphite oxide. XRD, SEM, EDS, TEM, HRTEM, SAED, XPS and Raman were performed to characterize the synthesized graphene. The results indicate that the synthesized graphene is transparent with several microns in size, which consists of 2–5 graphitic layers with high crystalline structure. The synthesized graphene can disperse homogenously in the NMP solvent.

Key words: graphene, microwave irradiation, synthesis in liquid phase
