摘　　要：以十六烷基三甲基溴化铵(CTAB)接枝氧化石墨烯(GO)为例,研究微波辐射改性氧化石墨烯(MGO)表面的特性,采用FT-IR、TGA、SEM等表征方法详细研究微波辐射时间和微波强度对GO表面改性的效果.实验研究发现:微波辐射强度为40 W,辐射时间60 min时,接枝效果最好;微波强度过大或微波作用时间过长,均会影响接枝效果;与水浴法相比,微波辐射法相对简单、可行和高效.Taking graphene oxide grafted cetyltrimethyalammonium bromide（CTAB） as example,the paper studies the surface properties of modified graphene oxide prepared by the microwave radiation.The effects of microwave radiation time and intensity on the surface of graphene oxide are characterized by FT-IR,SEM and TGA.Experimental results show that the grafting effect is the best when the microwave radiation intensity is 40W as well as the radiation time is 60min.It is found that when microwave intensity is too large or microwave time is too long,the effects of grafting will be weaken.Comparing with water bath method,the micro wave radiation method is relatively simple practicable and efficient.
