摘    要:石墨烯独特的原子结构赋予其电学、热学、力学等方面的优异性能,在诸多领域具有广泛的应用。氧化石墨烯不仅具有石墨烯结构特点,而且具有大量的含氧官能团,增强了对气体的吸附能力,更适合应用于气敏传感器。通过改进的Hummer方法制备了片状多层氧化石墨烯,并对不同浓度的NH3进行敏感特性测试。结果表明氧化石墨烯对NH3具有良好的响应,在(1.5~3.5)×10-4范围内呈线性关系。

关 键 词:氧化石墨烯  气体传感器  NH3

Abstract:Graphene have attracted wide attention for its unique characteristics(e.g.electronic,thermal,mechanical etc.).Graphene oxide not only possesses the intrinsic properties of graphene but also contains many oxygen-containing functional groups such as hydroxyl,epoxy,carboxyl and carbonyl groups.Those oxygen-containing functional groups may improve the adsorbability of graphene oxide to gases which is advantageous for its gas sensing properties.In this investigation,graphene oxide was synthesized by a modified Hummer’s method.The gas sensing properties of the as-prepared graphene oxide to NH3was then investigated.The results indicate that graphene oxide exhibited excellent sensitivities to NH3 with a well linearly relationship ranging from 1.5×10-4 to 3.5×10-4.
Keywords:graphene oxide  gas sensor  NH3
