摘要： A polypyrrole-coated graphene corrosion inhibitor container and its preparation method and a composite coating and its application are provided. The polypyrrole encapsulated graphene corrosion inhibitor container includes graphene oxide and a polyvinylo layer encapsulated on the surface of the graphene oxide. The invention is based on a polymerization reaction by mixing a polypyrrole acid solution, a graphene oxide dispersion, and an initiator to obtain a polypyrrole encapsulated graphene corrosion inhibitor container. The polypyrrole encapsulated graphene corrosion inhibitor container regulates the release rate of the corrosion inhibitor by wrapping the polypyrrole around the graphene oxide so that it is released rapidly in alkaline solutions and at a slower rate in neutral media. The results of the practical example show that the polypyrrole encapsulated graphene corrosion inhibitor container can regulate the release rate of the corrosion inhibitor and has excellent corrosion protection properties and corrosion protection durability.
