静电纺丝技术制备聚苯乙烯/石墨烯复合纳米纤维

摘要

通过静电纺丝技术制备了聚苯乙烯/石墨烯复合纳米纤维膜,利用扫描电子显微镜、傅里叶变换红外光谱、粉末X-射线衍射和激光拉曼光谱等技术对所制备的纤维膜结构和组成进行表征,并通过电化学法考察该复合纳米纤维膜的电活性。结果表明,石墨烯已掺杂到聚苯乙烯纤维中。与聚苯乙烯纤维膜相比,聚苯乙烯/石墨烯复合纳米纤维膜导电性能增强,表明本实验成功实现了对聚苯乙烯纤维的改性。%Polystyrene-Graphene composite nanofibres have been prepared by electrospinning technique.As-prepared nanofibres were characterized by scanning electronic microscopy,Fourier-transform infrared spectra,powder X-ray diffraction and Raman spectra.The electroactive of this composite nanofibres film was measured by electrochemical method.The results showed that graphene has been doped into polystyrene nanofibres.Compared with polystyrene nanofibres film,electrical conductivity of the composite nanofibres film is increased significantly.In this paper,modification of polystyrene fibers had been realized.
