Abstract

The invention relates to a co-doping polypyrrole material as well as a preparation method and an application thereof. The preparation method is characterized by comprising the steps: obtaining a polypyrrole / anthraquinone / graphene oxide composite material in a liquid which is formed from pyrrole monomer, anthraquinone-2-sodium sulfonate and graphene oxide by utilizing an electrochemical deposition method, and then electrochemically reducing the polypyrrole / anthraquinone / graphene oxide composite material to obtain the polypyrrole / anthraquinone / graphene oxide composite material. The preparation method can be carried out under the normal temperature, equipment is simple and easy to operate, and the selection range of the used co-doping system is wide. The porous micro-nano polypyrrole material prepared through the preparation method is excellent in conductivity and electrochemical performance and can be applied to a flexible energy storage device.

Description

technical field [0001] The invention relates to a co-doped polypyrrole material and its preparation method and application, in particular to a method for preparing a polypyrrole composite electrode material for a biocompatible battery. Background technique [0002] The power source used in existing implantable medical devices is mainly based on lithium batteries, such as Li / I 2 ,Li / V 2 o 5 ,Li / MnO 2 ,Li / Ag 2 V 4 o 11 and Li / CFx. The toxicity of the electrode material and the electrolyte itself requires the battery case to be isolated from the human body to ensure safety, which invisibly greatly increases the volume of the battery and implantable medical devices, which is not conducive to their miniaturization. Research on miniaturized implantable medical device power supply has become a hot and urgent research topic in the world. [0003] The structure of the biocompatible battery is relatively simple, and the principle is a metal / air battery. It uses the body fluid...
