▎ 摘　　要

NOVELTY - Preparing graphene oxide-polyaniline-gold nano-particle solution involves preparing graphene oxide powder, preparing the graphene oxide-polyaniline nano composite, preparing gold nano-particle solution, preparing graphene oxide-polyaniline-gold nano-particle nano-composite powder, dispersing the graphene oxide-polyaniline-goldnano-particle nano-composite powder in the chitosan solution, and forming the graphene oxide-polyaniline-gold nano-particle nano-composite solution. USE - Method for preparing graphene oxide-polyaniline-gold nano-particle solution. ADVANTAGE - The method uses graphene oxide with large specific surface area, nano-gold particles with good conductivity, and polyaniline good conductivity and can provide a 3 D net-shaped structure to improve the specific surface area of the composite, by the synergistic effect of graphene oxide, nano-gold particles, and polyaniline, and uses hydrothermal method to prepare graphene oxide-polyaniline-gold nano-particle nano-composite material.
