水溶性钛酸酯偶联剂改性石墨烯的制备与性能
|
摘要
采用改进的Hummers法制备氧化石墨烯(GO),然后在钛酸酯偶联剂TM-200S和水合肼共同作用下,对GO进行改性和还原,得到了功能化石墨烯。采用X射线光电子能谱、X射线粉末衍射仪和透射电镜等手段对GO的结构和性能进行表征。讨论了TM-200S用量、温度和反应时间对改性石墨烯的影响,确定了TM-200S改性石墨烯的较佳制备方案:GO与TM-200S的质量比为1∶7,反应温度为80℃,反应时间为8h。
TM-200 Stitanate coupling agent and hydrazine hydrate were added respectively to modify and reduced the graphene oxide prepared by the modified hummers method to obtain functionalized graphene oxide(GO).And the structure and properties of graphene oxide were characterized by XRD,TEM and SEM.And then the effects of titanate coupling agent content,temperature and reaction time on the modification of graphene were discussed.It was proved that the mass ratio of graphene oxide to TM-200 Swas 1∶7,the reaction temperature of 80℃,the reaction time of 8 h were the optimum preparation condition.
