-
摘要: 为了标记化学法制备石墨烯时引入的缺陷,采用紫外辐照的方法,利用Ag颗粒与含氧官能团之间的相互作用实现了对缺陷的定量标记.结果表明该方法能提供石墨烯表面缺陷的数量和分布信息.另外Ag纳米颗粒对石墨烯缺陷有修复作用,有利于提高石墨烯的导电能力.Abstract: Ultraviolet(UV) irradiation method was introduced to label the defects of graphene via the interaction between the Ag nanoparticles and oxygen-containing functional groups.Resultsshow that Labeling Ag nanoparticles can provide information about the density and locations of the defects and offere new possibilities for preparation of Ag nanoparticles modified graphene in a simple way. Furthermore,the conductivity of the graphene can be improved by Ag nanoparticles.
