Abstract:: Organic compounds containing unsaturated structures,π bond,C,N,S,O and other hetero atoms favor to be adsorbed on the metal surface,forming a protective film to preventing metals from corrosion,which are potential corrosion inhibitors.Plants are rich in such organic substances and to prepare corrosion inhibitors using the extracts of green plants (especially their ‘useless’ part) can not only obtain green chemical products,but also can reduce the burden of agricultural waste.It will be of great significance for optimizing the implementation of ecological resources.In this study,the corrosion inhibitive mechanism of plants extracts was summarized,the research progress of plants extracts as corrosion inhibitors was reviewed and the development trend of green plants extracts as environmental-friendly corrosion inhibitors was analyzed.It was expected to provide a support for the design of new green corrosion inhibitors and the high-value application of green plants.
