Preparation method and application of urushiol iron conductive coating with high adhesive force and high stability

Abstract

The invention relates to a biomass multifunctional coating, in particular to a preparation method and application of a high-adhesion and high-stability urushiol iron conductive coating. The urushiol is used as a main component, in-situ oxidative polymerization of pyrrole is directly carried out in a urushiol iron polymer network structure through an in-situ hybridization method based on ferric ion induced oxidative polymerization and metal coordination, and the urushiol iron conductive coating with high adhesive force, high stability and good conductivity is obtained. The conductive coating may be used to assemble a strain sensor. The urushiol is derived from a natural plant, is rich in resource and is non-toxic, and meanwhile, the technology realizes functional interaction of high conductivity of polypyrrole and excellent characteristics of high adhesive force, corrosion resistance and the like of the urushiol iron polymer, so that the problems that a traditional polypyrrole conductive coating is poor in adhesive force to the surface of a base material and poor in mechanical property are solved.
