EPOXY PHOSPHONATE ESTER AS A COUPLING AGENT FOR TRANSITION METAL AND METAL OXIDE SURFACES

摘要

A method for surface modification of a substrate comprising surface oxide and/or hydroxy groups, with a compound comprising an ester group and an epoxy ring, wherein the epoxy group remains intact after the reacting. A method for surface modification of a substrate comprising surface oxide and/or hydroxy groups, with a compound comprising an ester group and a functionalized epoxy ring, wherein the functionalized epoxy group remains intact after the reacting. A composite material comprising surface-modified metal oxide nanoparticles dispersed within a polymeric material, wherein the surface modification comprises a compound comprising an ester group and an epoxy ring is also described.

1. A method of forming a surface-modified substrate, said method comprising:
(a) providing a substrate having a surface, said surface comprising an oxide and/or an —OH group thereon; (b) providing a compound comprising an ester group and an epoxy ring; (c) reacting said compound with said oxide and/or said —OH group so as to yield the surface-modified substrate, said epoxy ring remaining intact after said reacting.
