Method for preparing polypyrrole/gold nano composite

The invention relates to a method for preparing a polypyrrole/gold nano composite, belonging to the technical field of material, comprising the following steps: uniformly stirring deionized water, surfactant and cosurfactant at room temperature, adding pyrrole in the system, and adding certain concentrated hydrochloric acid to adjust the PH value to 0.8-1.3; adding auric chloride acid solution slowly to react for 3-6h; after the reaction, carrying out demulsification, centrifugation and drying to obtain polypyrrole/gold nano composite particles. The polypyrrole/gold nano composite particles prepared by the invention are in a good dispersion and regular tetrahedron morphology, have good conduct electricity, good electrical conductivity, and are capable of being used in the fields of electrode material, luminescent material, electromagnetic shielding material, anticorrosion paint and the like of secondary battery. Simultaneously, the preparation method has the advantages of simple process, low reaction environm
