Synthesis and Use of Epoxy Phosphonate Ester as a Coupling Agent for Metal Oxide Interfaces

Abstract

A phosphonate organic monomer, O,O-diethyl oxiran-2-ylmethylphosphonate ester (DEOMP) was synthesized by an Arbuzov reaction and purified. DEOMP was applied via an in situ hydrolysis process for the surface modification of metal oxide nanoparticles. The surface modified nanoparticles provide improved wetting, dispersion, and strength through surface coupling with epoxy monomer-polymer formulations. The objective was to determine competition between the ligand adsorption resulting in surface modification of the nanoparticles process vs. undesired phosphonic acid-catalyzed epoxide ring opening during the modification process during the overall ester hydrolysis-phosphonate surface adsorption modification process.
