NOVELTY - Method for preparing graphene oxide/conductive polymer composite gel involves adjusting pH of dopamine hydrochloride solution to 8-9 and marking as first solution; adding conductive polymer to graphene oxide water dispersion liquid, stirring and ultrasonically processing, uniformly dispersing and recording as second solution; adding first solution into second solution and stirring uniformly, carrying out hydrothermal reaction, taking out product, washing by deionized water, and freeze-drying. USE - The method is useful for preparing reducing graphene oxide/conductive polymer composite gel, which is useful in electrochemical energy storage device, intelligent portable electronic product, electric automobile and machine learning, artificial intelligence, and Internet of Things improvement of function. ADVANTAGE - The method uses dopamine coated on the graphene oxide and conductive polymer surface, self-polymerization to form poly-dopamine, promoting the mutual dispersion of graphene oxide, so as to improve the electrical performance of the composite gel. In addition, it also controls the electrochemical properties of composite gel by controlling the proportion of each component. The reduction-oxidation graphene/conductive polymer composite gel provided by the method is simple; there is no organic solvent, no pollution to the environment; it does not need special instrument and has low cost.
