叶酸功能化石墨烯的制备

摘要

采用一锅法和气液界面法,以纳米四氧化三铁为交联剂作为叶酸和石墨烯之间的交联剂,制备得到了具有一定功能的叶酸功能化石墨烯复合材料.采用红外光谱法、扫描电子显微镜和电化学方法对其结构和性能进行分析.结果表明,乙二醇和氧化石墨烯浓度均为1 mg/mL时,获得产物具有较好的磁性分离性能;气液界面法制备的产物具有更好的晶型和优异的电化学响应信号.%One-pot method and gas-liquid interface method were employed to prepare folic acid functionalized gra-phene composite nanomaterials respectively with nano ferroferric oxide as the crosslinking agent between folic acid and graphene.Infrared spectroscopy,scanning electron microscope were used to analyze its structure, properties and electrochemical properties.The results indicated that the product with the reducing agent glycol concentration of 1 mg/mL has good magnetic separation performance;And,the product prepared by gas-liquid interface method exhibit better crystal structure and excellent electrochemical response.
