Title:
COMPOSITE MATERIAL, MICROELECTRODE, AND PREPARATION METHOD THEREFOR AND USE THEREOF 
Document Type and Number:
WIPO Patent Application WO/2024/092750
Kind Code:
A1
Abstract:
Provided are a composite material, a microelectrode, and a preparation method therefor and the use thereof, which belong to the technical fields of nanomaterials and bioelectronic materials. The composite material is of a structure of metal nanodendrites surface-modified with a doped conductive polymer, wherein the doped conductive polymer comprises polyethylene dioxythiophene and a doping agent. In the microelectrode, the composite material is used as a decorative material on an electrode material, such that the effective surface area of the electrode is greatly increased, the comprehensive performance of the electrode is improved, and the adhesive force is good. The microelectrode is prepared by means of an electrochemical deposition method, and has good coating uniformity, good electrochemical and biological properties and good repeatability, and the method is simple, is easy to operate, and can realize batch production. The composite material can be extensively used in the fields of neural electrode stimulation/recording, electrochemical sensing/catalysis, or biological pollution prevention.
