Advances in Surfactants as Inhibitors for Corrosion Protection
摘要
The versatile applicability of surfactants is well known. The amphiphilicAmphiphilic molecularMolecular structureMolecular structure ofStructure surfactantsSurfactant makes them employable in variousIndustrial applications industrialIndustrial applicationsApplication. SurfactantsSurfactant find immense applicationsApplication in the corrosionCorrosion inhibitionCorrosion inhibition ofInhibition metals and alloysAlloy. The polarPolar head groupPolar head group of surfactants facilitates their absorptionAbsorption on the metalMetal surfacesMetal surface. In contrast, the non-polarNon-polar hydrophobicHydrophobic moietyAmphiphilic moieties formsHydrophobic moiety a protective layerProtective layer above it, thus protecting the metallicSurface surfaceMetallic surface by repellingWater molecule waterWater moleculesMolecule present in the environment. The protective hydrophobicHydrophobic layer intervenes in the corrosionCorrosion reaction by forming a diffusionDiffusion barrierDiffusion barrier or by blocking reactionBlocking reaction onto both of the electrodesElectrode and thus prevents the transportTransport of waterWater and other corrosiveCorrosive activeCorrosive activity species.
