Plant Extracts as Corrosion Inhibitors

Corrosion inhibitor, as an additive that can effectively inhibit the corrosion of metals in liquid medium, has been widely used in industrial field. However, due to the demand of environmental protection and the implementation of green and sustainable development strategy, the research and development of corrosion inhibitors that do not have harmful effects on the environment and ecology has become the need of the development of the times. Extracting effective components from plants as corrosion inhibitors is undoubtedly a feasible direction. Therefore, researchers have carried out a lot of useful experimental research and application exploration in this area. This chapter summarizes the research of plant corrosion inhibitors in recent years, and analyzes the shortcomings in the current research of plant corrosion inhibitors and the potential development direction of plant corrosion inhibitors in the future.
