1. 毕业设计（论文）的内容和要求

氧化石墨烯(go)是石墨烯的衍生物，具有与石墨烯相似的结构，但go层上有许多的含氧基团，其片层上下表面接有环氧基团和羟基，片层边缘为羰基和羧基。氧化石墨烯继承了石墨烯的高比表面积(2630 m²/g)，同时引入的基团加大了片层之间的间距，增强其相容性，制作成本低，使其具有广泛的应用。由于其表面的含氧基团，氧化石墨烯具有良好的亲水性、生物相容性及电化学性能，且其可以较好的与无机粒子进行复合。

磷酸钙是无机硬组织的组成成分，它具有良好的生物性能，常被用来制备各种形貌的生物材料，而球形材料比其它材料具有更好的流动性、填充性和较大的比表面积。两者复合可以增强其稳机械强度，生物相容性以及比表面积。因此本实验目的为制备多孔并具有应用价值的氧化石墨烯/磷酸钙复合微球，且稳定性好，生物活性好。同时实验中研究反应时间、反应温度对产物的影响，最后探索了磷酸钙复合微球的形成机制及制备。

本课题拟将氧化石墨烯以自组装的方法包裹在碳酸钙微球表面形成复合微球，再以其为模板使用pbs矿化为磷酸钙复合微球。
