摘要

提供了一种在聚苯乙烯磺酸钠（PSS）的帮助下，合成氧化还原石墨烯稳定水溶液分散体的简单方法。这种方法制备的分散体非常稳定，长达几个星期都没有聚集或者沉淀。通过各种方法对材料进行了表征。扫描电子显微镜（SEM）和紫外-可见光吸收光谱的结果表明PSS紧密地包裹住了石墨烯，形成功能化石墨烯；石墨烯的亲水性大大提高。傅里叶变换红外光谱（FTIR）表明O=S=O官能团的存在，说明石墨烯中存在PSS。X射线光电子能谱（XPS）提供了C/S的原子浓度比等，进一步说明了PSS的存在。结果表明，覆盖有PSS的氧化还原石墨烯能够应用于石墨烯的复合材料中。

Abstract

With the aid of poly(sodium 4-styrenesulfonate) (PSS)

a facile one-step method of producing stable hydrosoluble dispersion of reduced graphene oxide is reported. The prepared dispersion was very stable and no aggregation or precipitation was observed for several weeks. The obtained nanosheets were characterized by various diagnostic techniques. The results by scanning electron microscopy (SEM) and UV-Vis spectrum showed that PSS was tightly attached to the reduced graphene oxide and the hydrophilicity of graphene was greatly improved. Fourier transform infrared spectroscopy (FTIR) spectrum indicated the existence of O=S=O groups in PSS. X-Ray photoelectron spectroscopy (XPS) spectrum provided further evidence about the C/S atomic ratio and sulfur-bonded carbon atoms from PSS. The results shown in this study proved that this PSS-coated reduced graphene oxide could be implemented in graphene-based composites.
