摘要
石墨由于在新能源、信息技术等国民经济先导性产业和高端制造产业的广泛应用,得到越来越多的关注.选用两种颗粒度不同的典型石墨为原材料,经过物理表征后发现,两种典型石墨的比表面积相差无几,但其孔径差别比较大,两种典型石墨的孔径分别为5.8 nm和1.2 nm;采用改性的Hummers方法制备的前基体1-氧化石墨烯(1-GO)和2-氧化石墨烯(2-GO),对制备的1-GO和2-GO前基体进行物理表征,虽然两种GO前基体表面都已经嵌入了含氧官能团并呈现单层结构,在后续阶段以2-GO为基体制备的石墨烯相关基体与其它材料进行复合时却表现出明显不同的性能.
Graphite has received more and more attention due to its extensive application in new energy,information technology and other leading industries of the national economy and high-end manufacturing industries.Two types of typical graphite with different particle sizes are selected as raw materials.After physical characterization,it is found that the specific surface area of the two types of typical graphite is almost the same,but their pore diameters are quite different.The pore diameters of the two types of typical graphite are 5.8nm and 1.2nm respectively.Then,1-GO and 2-GO are prepared using the modified Hummers method based on the two types of typical graphite,and the prepared 1-GO and 2-GO matrices are physically characterized,Although the surfaces of the two pre GO matrices have been embedded with oxygen containing functional groups and present a monolayer structure,graphene related matrices prepared with 2-GO as the matrix in the subsequent stage show significantly different properties when compounded with other materials.
