大学化学综合实验氧化石墨烯制备工艺的改进

Improvement of Preparation Process of Graphene Oxide for Comprehensive Experiment of College Chemistry

石墨烯是一种以sp^2杂化方式形成的蜂窝状平面薄膜,其具有良好的强度、柔韧、导热等特性,在化学、物理、生物医学、材料科学等领域掀起了研究热潮。石墨烯一般由氧化石墨烯还原而得。为了提高学生对科学前沿的了解,增强学生的科研兴趣,通过改进氧化石墨烯制备工艺,缩短制备时间,提高实验成功率,调动学生实验的积极性。

Graphene has attracted great attentions, due to its intrinsic 2-D structures, outstanding physical and chemical properties as well as their promising potential applications in the areas of material science, electronic science, biomedicine and catalyst carrier etc. The improved method has much more successful experimental rate with less preparation time compared with the common used method. Students show their very interest in this experiment. The good effect indicates that the improved experimental design can be used as the content of＂in comprehensive experiment of college chemistry＂
