Popis

General description

Octylphosphonic acid (OPA) forms a self-assembled monolayer (SAM), which serves as a protective anti-corrosive phosphonate layer on a variety of surfaces.

Application

OPA can be used as a surfactant that may be added to silver (Ag)/titanium oxide (TiO₂) for uniform dispersion into the polymeric matrix. It may be coated on indium-tin oxide (ITO) substrates, which can be used for super-resolution microscopy. OPA based charge blocking layer may be used to prevent leakage of current in a hybrid dielectric film.
