摘要

摘要: 采用剪切-摩擦机理，通过卷曲将双轴取向聚丙烯纤维表面转变成石墨纳米片，从而制备出炭纳米卷。通过光学和扫描电镜、透射电镜和红外光谱仪等手段对炭纳米卷的形貌进行分析。微-拉曼测试表征了卷曲结构的形貌变化。从振动的G模式分裂可知，石墨片取向度与卷曲轴有关。

Abstract: Carbon nanoscrolls (CNSs) are produced by rolling up the graphite layer in graphene nanoplatelets on a nanofibrous bi-axially oriented polypropylene surface by a shear-friction mechanism. Microstructures of the CNSs are characterized by optical and scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy and micro-Raman spectroscopy. Results indicate that the CNSs have a long tubular and fusiform structure with a hollow core surrounded by few graphene layers. The orientation of the graphite lattice with respect to the scroll axis is accurately determined from the split of the vibrational G mode by polarized micro-Raman spectroscopy. Morphological changes produced by the rolling are also described.
