In one embodiment, the present invention relates to a substrate for an electrical device including a coating, wherein the coating comprises an oxygen plasma resistant polymer prepared from a mixture containing a polymerization material and a polycondensation product of a partially hydrolyzed chelated metal oxide precursor. In another embodiment, the present invention relates to a component for an electrical device comprising an oxygen plasma resistant polymer prepared from a mixture containing a polymerization material and a polycondensation product of a partially hydrolyzed chelated metal oxide precursor. In yet another embodiment, the present invention relates to a microelectronic device comprising an oxygen plasma resistant polymer prepared from a mixture containing a polymerization material and a polycondensation product of a partially hydrolyzed chelated metal oxide precursor.

Oxygen plasma resistant polymer for electrical devices

In one embodiment, the present invention relates to metal oxide sols comprising a liquid and a polycondensation product of about 2 to about 5,000 monomers of a partially hydrolyzed chelated metal oxide precursor. In another embodiment, the present invention relates to a process for making a metal oxide sol comprising contacting a metal oxide precursor with a multifunctional compound in a liquid to provide a chelated metal oxide precursor; contacting the chelated metal oxide precursor with a hydrolyzing agent to provide partially hydrolyzed chelated metal oxide precursor monomers; and permitting the partially hydrolyzed chelated metal oxide precursor monomers to polycondense thereby forming a metal oxide sol.

Metal oxide sols and process for making the same

In one embodiment, the present invention relates to a polymer prepared from a mixture containing a polymerization material and a polycondensation product of a partially hydrolyzed chelated metal oxide precursor. In another embodiment, the present invention relates to a process for making a polymer involving contacting a polymerization material with a metal oxide sol comprising a liquid and a polycondensation product of a partially hydrolyzed chelated metal oxide precursor to form a mixture and at least one of polymerizing and curing the mixture of the polymerization material and the polycondensation product.

Polymers made with metal oxide sols

A process for providing a metal oxide-containing coating on a compatible substrate, the coating being transparent to a photocuring source output and upon cure being resistant to electrical stress. The process of the invention comprises a) preparing a precursor composition comprising a mixture of a stabilizer and a metal oxide sol precursor material; b) combining the stabilizer/metal oxide sol precursor material mixture with a photocurable base resin without high shear mixing to achieve a homogeneous, transparent composition; c) coating the substrate material with the transparent composition; and d) photocuring the coated substrate bearing the transparent composition, wherein the cured coating is homogenous and transparent and remains transparent in the use state, thereby rendering the coating corona resistant. This invention further relates to the coated substrate.
