Abstract

A three-layer vesicular polyaniline / graphene composite material and a preparing method thereof are disclosed. The composite material is prepared by firstly preparing layer-number-adjustable SiO2, preparing a layer-number-adjustable SiO2 / polyaniline composite material by adopting the layer-number-adjustable SiO2 as a hard template and adopting aniline as a raw material through an in-situ polymerization process, etching SiO2 to obtain three-layer vesicular polyaniline, preparing a three-layer vesicular polyaniline / graphene oxide composite material through a graphene oxide self-assembling process, and preparing the three-layer vesicular polyaniline / graphene composite material through a high-temperature hydrothermal reduction process. The vesicular polyaniline / graphene composite material having same layer numbers can be obtained by regulating the layer-number-adjustable SiO2. No oxidant or reductant is needed. The method is green. During preparation of the three-layer vesicular polyaniline / graphene composite material, the method is simple, safe in process, low in energy consumption and high in operability.

Description

technical field [0001] The invention relates to a three-layer vesicular polyaniline / graphene composite material and a preparation method thereof, and belongs to the intersecting field of organic / inorganic nanometer composites and functional polymer materials. Background technique [0002] Supercapacitor is a new type of green energy storage element, which has been widely concerned because of its large specific surface area, good conductivity, and multi-layer structure. Conductive polymers and carbon materials are the main pillar materials to realize the charge storage and release of supercapacitors. Among them, polyaniline has become the fastest researched conductive material because of its good thermal stability, chemical stability and electrochemical reversibility. One of the polymer materials; graphene is a two-dimensional planar structure with hexagonal structural units formed by the close packing of carbon atoms. It has the advantages of large specific surface area, hig...
