摘　　要：分别采用绿色还原剂抗坏血酸(AA)和单宁酸(TA)对氧化石墨烯(GO)进行还原,制得还原氧化石墨烯(RGO)和TA修饰的还原氧化石墨烯(RGOA)。通过对RGO和RGOA进行表征和测试。结果表明:在水溶液体系中AA和TA均可有效地还原GO。制得的RGO和RGOA形貌、亲水性和导电性存在显著区别:RGO为具有较大比表面积且碎裂、无序固体结构,电导率显著提高,与RGOA相比还原程度更高,但亲水性较差;RGOA则由于TA的多酚羟基的引入,呈现为膨胀卷曲絮状结构,电导率有所提升,亲水性得到了明显的改善。Green reducing agents,ascorbic acid(AA)and tannic acid(TA),were used to reduce graphene oxide(GO),yielding two types of reduced graphene oxide(RGO)and TA-modified reduced graphene oxide(RGOA),respectively.It was found that both AA and TA could effectively reduce GO in aqueous solutions through the characterization and testing of RGO and RGOA.The prepared RGO and RGOA exhibited significant differences in morphology,hydrophilicity,and conductivity.RGO was a fragmented and disordered solid structure with a larger specific surface area.The electrical conductivity was significantly increased,and the reduction degree was higher than RGOA,but the hydrophilicity was poor.In contrast,RGOA presented an expanded and curled flocculent structure due to the introduction of the polyphenolic hydroxyl groups of TA,and the electrical conductivity was improved slightly and the hydrophilicity was enhanced obviously.
