Electrospun Nanofibers for Coating and Corrosion

Metallic and alloy materials are needed special surface treatments and coatings to be acted as environmentally anticorrosion. Corrosion is a typical critical issue in the performance of metallic components used in industrial applications. Surface engineering techniques have been well developed with the advent of nanotechnology for the improvement of corrosion resistance. Traditional techniques of coating used chromates which are environmentally creating human health problems. To resolve this issue, surface modification by using nanostructure coating is the hot topic of research in the field of anticorrosion properties of nanomaterials. Among the various nanoscale deposition on the metallic or alloy materials such as sputter deposition, physical vapor deposition, chemical vapor deposition, laser-assisted ablation, electrodeposition, atomic layer deposition, spin-coating, chemical bath deposition, etc., the deposition by polymeric fibrous materials at the nanoscale has found to be well anticorrosive. The polymeric nanofibers coating on metal by electrospinning is an effective technique used for the reduction of corrosion rate. This chapter is mainly focused on the fabrication technique of electrospun nanofibers which can be efficiently used as corrosion inhibitors as well as self-healing agents to reduce the corrosion rate and compared with other coating techniques.
