Abstract：The subject 'cellulose nanofiber / graphene / polyaniline nanorod flexible linear supercapacitor' uses nanocellulose, graphene and polyaniline as experimental materials. This paper summarizes the performance, preparation methods and research status of the raw materials of the subject. Nano-cellulose was prepared as a substrate improving material from the combination of acid-base treatment and mechanical treatment in bamboo powder, and polyaniline and graphene were used as supercapacitor electrode fillers. Redox graphene is prepared by the Hummer method, which is safe and stable. Polyaniline is prepared by chemical oxidative polymerization. Finally, nanocellulose, graphene oxide and polyaniline composites were prepared by wet spinning. The research is mainly to explore the use of nanocellulose/graphene/polyaniline flexible linear all-solid supercapacitors. The nanocellulose, graphene oxide, reduced graphene oxide and polyaniline molecules were analyzed and identified by Fourier transform infrared spectroscopy. The surface morphology of the nanofibers was analyzed by scanning electron microscopy and analyzed by laser Raman spectroscopy. Graphene, reduced graphene oxide, polyaniline molecular structure for analysis and identification.

1纤维素现状
纤维素是人类，古老和富裕的重要天然可再生资源。纤维素植物细胞壁的主要部分，不溶于水，不溶于常见的有机溶剂。纤维素及其衍生物在工业，生命，建筑和化学领域的生产，开发和富集做出了重大贡献。
纤维素是由beta;－D-吡喃型葡萄糖基（失水葡萄糖）组成，分子式为(C6H=10O5)n。天然纤维素纤维和再生纤维素纤维在形成时都有某些因素迫使高分子轴与纤维轴或多或少维持一定的平行程度，这种性质称为取向。它可用取向度定量地表述。聚合物的取向表明机械性能，光学性质和纤维的各向异性。
2纳米纤维素现状
近年来，纳米纤维素的研究不断发展，是一种具有良好发展潜力的生物化学材料。纳米纤维素作为一种新型绿色材料，除了储量丰富和循环利用外，还具有优良的纳米结构、良好的灵活性和机械性能。因为其众多的优点，纳米纤维素也有着广阔的应用前景。
