Polystyrene as a thin film on arbitrary substrates or pellets form defective graphene/graphitic films or powders that can be dispersed in water and organic solvents. The materials were characterized by visible absorption, Raman and X-ray photoelectron spectroscopy, electron and atomic force microscopy, and electrochemistry. Raman spectra of these materials showed the presence of the expected 2D, G, and D peaks at 2750, 1590, and 1350 cm, respectively. The relative intensity of the G versus the D peak was taken as a quantitative indicator of the density of defects in the G layer.
聚苯乙烯以薄膜形式存在于任意基底上，或以颗粒形式形成有缺陷的石墨烯/石墨薄膜或粉末，这些薄膜或粉末可分散于水和有机溶剂中。通过可见吸收光谱、拉曼光谱和X射线光电子能谱、电子显微镜和原子力显微镜以及电化学对这些材料进行了表征。这些材料的拉曼光谱显示，在2750cm、1590cm和1350cm处分别出现了预期的2D、G和D峰。G峰与D峰的相对强度被用作G层中缺陷密度的定量指标。
