General description

Octadecylphosphonic acid (OPA) is used as a self-assembled monolayer that forms a surfactant which strongly bonds with the surface atoms of different metal oxides. It provides hydrophobic properties and covers a higher surface area than the predominantly used silanes.

Application

Anti-corrosive coatings on cupronickel (CuNi) can be formed by fabricating a protective film of OPA by dip coating method. OPA may be used in the preparation of indium oxide(In2O3) nanowire transistor than can find potential application in the growth of fast switching and low noise nano-electronic devices. It may be used for self-cleaning and oil/water separation based applications as it forms a superhydrophobic layer on the copper mesh.
