摘要
氧化还原法制备石墨烯是目前被广泛采用的一种方法.但用此方法制备的石墨烯片比较容易产生皱褶或出现折叠现象,厚度偏大、有很多缺陷.所以用此方法制备的石墨烯缺陷偏多、导电性不理想,使其在电极材料方面的应用受到了很大的限制.本文对采用氧化还原法制备石墨烯过程中的主要工艺参数进行了研究,并通过拉曼光谱的测试结果来表征和分析石墨烯的缺陷程度,最终确定石墨烯的结构与主要工艺参数之间的关系.
At present, the method that is widely used to prepare graphene is oxidation-reduction method. But the graphene prepared by this method often produces wrinkle, has much defects, and its thickness is bigger. So the graphene prepared by this method was restricted using on the field of electrode materials. The main technological parameter in the process of preparing graphene by using oxidation-reduction was studied in this paper. And through the results tested by Raman spectrometer to analyze the degree of the graphene＇ s defects, it can finally be confirmed the relationship between the graphene＇ s structure and the technological parameter.
