Description

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.
