1. 毕业设计（论文）的内容和要求

本课题主要是先利用改进的Hummers法来制备氧化石墨烯(GO)，然后以GO为前驱体，通过一步水热法制备蓝色荧光石墨烯量子点，并对已制备的石墨烯量子点运用傅里叶变换红外（FT-IR）光谱、紫外吸收（UV-Vis）、透射电镜（TEM）、荧光光谱仪等表征，同时研究石墨烯量子点在图案化方面的应用。

通过本课题的研究，使学生了解石墨烯及石墨烯量子点的相关知识，并对材料化学工程、仪器分析有更进一步的认识；培养学生独立查找和阅读国内外文献的能力；掌握化学实验的基本技能（实验装置的设计与安装、仪器的使用、操作等），了解各种表征手段、实验室安全规程、各级药品的储存与保管，锻炼学生独立思考和独立实验的能力；能独立使用软件处理相关数据，具有初步的整理和分析数据的能力，利用Word撰写论文以及使用PowerPoint制作答辩报告的能力。
