碩士 === 中原大學 === 化學研究所 === 100 === Graphene with fast electron mobility, high mechanical strength, high conductivity and transparent characteristics, therefore, becomes very wide applications in electronic components. In this study, graphene was reduced from graphene oxide (GO) by using Hummer’s methods. By adding commercially available polyethylene glycol (PEG) with molecular weight 600, 6000, 20000, and 35000 for slurry formation, we developed the graphene films on glass substrate with good conductivity for electrode applications. The characteristics of graphene/PEG films were studied by using SEM, UV-vis, four proble point conductivity measurement, Raman spectroscopy, and AFM. It was found that PEG with molecular weight around 600~6000 is a better choice for the formation of graphene film on glass substrate in term of conductivity and their trasparancy.
