摘要
以聚丙烯腈、氧化石墨烯为原料,采用静电纺丝工艺制备氧化石墨烯/聚丙烯腈纳米纤维,利用SEM对其微观结构进行观察,确定了静电纺丝的最佳配比参数。通过预氧化及炭化工艺,获得比表面积大、孔径均匀的石墨烯/纳米炭纤维。经SEM、TEM、DSC和TGA等测试对石墨烯/纳米炭纤维进行分析表征。结果表明,石墨烯以游离、包裹以及嵌入3种方式与纤维连接形成一个"面到线"的网络结构,比表面积增大,与纳米炭纤维相比,比表面积提高了43.72 m^2/g,为437.36 m^2/g。
Using graphene oxide and PAN as raw materials, r GO/PAN nanofibers were prepared by electrospinning, and then the optimum ratio parameter were determined by SEM which was observed the microstructure. The r GO/PCNFs with large surface area and uniform pore size were obtained by pre-oxidation and carbonization. The SEM, TEM, DSC, TGA were used to characterize the microstructures of the r GO/PCNFs. The results show that graphene oxide connects to the fibers in three ways-free, wrapped and embedded to form a "face to the line" network structure. Compared with carbon nanofibers, the specific surface area increased by 43.72 m^2/g, which is 437.36 m^2/g.
