Abstract

The invention discloses a preparation method of a carbon nitride nanofiber conductive polymer composite material with high specific capacity and low leakage current. The molecular monomer is added to the water-soluble carboxylated graphene suspension emulsion, and then the oxidant solution is added, and after cleaning, nitrogen-doped porous carbon material is made, and finally the nitrogen-doped porous carbon material is mixed in the water-soluble carboxylated graphene suspension emulsion. Secondary modification is carried out in the medium to make a high specific volume carbon nitride nanofiber conductive polymer composite material. The nitrided carbon nanofiber conductive polymer composite material can be prepared quickly, effectively and cheaply by this method, while ensuring the nitrogen content of the nitrided carbon nanofiber conductive polymer composite material, increasing its specific capacity, and at the same time passing The control of variables such as temperature and nitrogen flow rate ensures that the carbon nanofiber nitrided conductive polymer composite material can be reacted and formed stably and effectively, and its low leakage current performance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of carbon materials and chemical power sources, in particular to a method for preparing a carbon nanofiber nitrided conductive polymer composite material with high specific capacity and low leakage current. Background technique [0002] Today, with the emphasis on the ecological environment and economic benefits, people are committed to obtaining low-cost and clean energy from solar and wind energy, which will fundamentally meet the growing energy demand. However, only by converting these renewable energies into electrical energy and storing them can they be used anytime and anywhere, obviously this will not be able to meet people's daily needs. Supercapacitors offer a promising way to quickly store electrical energy. In addition, supercapacitors are also widely used in many other fields, such as: mobile electronic equipment, hybrid vehicles and backup power systems. As a new type of energy device, superca...
