摘    要:用改进的Hummers法制备了氧化石墨, 经超声和离心处理, 将氧化石墨转化为氧化石墨烯胶体(Graphene Oxide, GO), 用十六烷基三甲基溴化铵(CTAB)对GO进行改性制备了改性氧化石墨烯(Modified GO, MGO), 采用FT-IR、AFM、TEM、SEM、TGA等手段对材料结构和性能进行了表征, 结果表明: 所制得的GO胶体具有很好的悬浮稳定性, 其厚度小于1.16 nm, 表面含丰富的含氧官能团, GO片层呈现出很多皱褶; CTAB与GO之间存在化学键键合作用, 改性后GO的热稳定得到一定程度的提高。

关 键 词:石墨  氧化石墨烯  十六烷基三甲基溴化铵  有机改性  热稳定性

Abstract:Graphite oxides were prepared by improved Hummers method.After ultrasonic and centrifugal treatments,the graphite oxides were transferred to graphene oxides(GO),which was then modified further with cetyltrimethyl ammonium bromide(CTAB) to obtain the product named as modified GO(MGO).The structures and properties of the raw material,GO and MGO were characterized by FT-IR,AFM,TEM,SEM and TGA.The results showed that the GO sol possessed a good suspension stability,with a thickness less than 1.16 nm and many oxygen-containing groups on the surface.Some wrinkles could be observed on the GO sheets.There occured chemical bonding between CTAB and GO.The thermal stability of MGO was improved to some extent.
Keywords:graphite  graphene oxide  cetyltrimethyl ammonium bromide  organic modification  thermal stability
