Patterning on surface with high thermal conductivity materials
First Claim
1. A method of making high thermal conductivity paper comprising:
- adding high thermal conductivity materials and a solvent for the high thermal conductivity materials onto or within a substrate consisting essentially of mica;
evaporating the solvent such that the high thermal conductivity materials form a specific pattern on or within the substrate; and
producing a mica paper product from the substrate;
wherein the produced mica paper product comprises portions having the specific pattern of high thermal conductivity materials and portions comprising mica without the specific pattern; and
wherein the plurality of high thermal conductivity materials comprises at least one of nanofillers, diamond like coatings on the paper product, or diamond like coatings on nanofillers.

Abstract
The present invention provides for high thermal conductivity paper that comprises a host matrix (10), and high thermal conductivity materials (12) added to a surface of the host matrix in a specific pattern (12). The high thermal conductivity materials are comprised of one or more of nanofillers, diamond like coatings directly on the host matrix, and diamond like coatings on the nanofillers. In particular embodiments the specific pattern comprises one or more of a grid, edging, banding centering and combinations thereof and the high thermal conductivity materials cover 15-55% of the surface of the host matrix. Multiple surfaces, including sub layers my have patterning.
