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.

Photocurable composition for electrical insulation

A magnetic top stick for use at the opening portion of a core slot of an electromagnetic device includes a group of magnetically anisotropic members arranged in a substantially non-magnetic body adapted to fit snugly within the core slot. The magnetic properties of the group of members combine to provide the top stick with an overall high magnetic permeability in the depth direction of the core slot and overall low magnetic permeabilities in the width and longitudinal directions of the core slot. A convenient method of manufacturing the top stick includes first forming magnetically anisotropic sheets by cold rolling and annealing, then laminating and heat processing the sheets with B stage materials to generate a unitary laminated structure. The unitary laminated structure is sectioned into multiple magnetic flux bars which are in turn disposed in the non-magnetic body forming the top stick.
