Graphene won the 2010 Nobel Prize after the researchers have aroused widespread concern,with the rare performance of graphite and in-depth study found that the electrical properties and stability of graphene is not fully equipped with other materials.Polyaniline as one of the three conductive polymer materials,although with good conductivity but stability is not optimistic,limiting the application of polyaniline,so this article around the two materials of electrical properties and stability to do some research,In order to achieve the advantages of the two complement each other.1.In this paper,a preparation method of water-based polyaniline encapsulated graphene material was studied.The modified material was applied to anti-static coating,and its anti-static performance was tested.The results show that it has good anti-static effect,Meet the industrial application standards,and has a very good stability,is an environmentally friendly anti-static coating.2.Next,this paper reports a simple method for the preparation of graphene / polyaniline(G / PANI)fibers by direct in situ polymerization.And the two fibers are immersed in the H2SO4-PVA electrolyte to obtain a solid-state graphene / polyaniline supercapacitor.The super capacitor is fixed on the PET film to obtain a flexible all-solid supercapacitor,and the all-solid supercapacitor Performance has been tested.3.In the end of this paper,the preparation method of the second part has been improved,and the supercapacitor capacitor material of polyaniline encapsulated graphene fiber has been prepared by more environmentally friendly electrochemical method.The capacitance and cyclic stability of the material are In order to obtain higher cycle stability,this paper also studies the causes of capacitance loss and uses the method of low voltage window to avoid the loss of capacitance and obtain better cycle stability.
