Surfactant-wrapped chemically converted graphene sheets obtained from reduction of graphene oxide with hydrazine were functionalized by treatment with aryl diazonium salts. The nanosheets are characterized by X-ray photoelectron spectroscopy, attenuated total reflectance infrared spectroscopy, Raman spectroscopy, atomic force microscopy, and transmission electron microscopy. The resulting functionalized nanosheets disperse readily in polar aprotic solvents, allowing alternative avenues for simple incorporation into different polymer matrices.
通过用肼还原氧化石墨烯得到的表面活性剂包裹的化学转化石墨烯片，经芳基重氮盐处理后实现了功能化。这些纳米片通过X射线光电子能谱、衰减全反射红外光谱、拉曼光谱、原子力显微镜和透射电子显微镜进行表征。所得的功能化纳米片易于分散在极性非质子溶剂中，为简单地掺入不同聚合物基质提供了其他途径。
