Claim:
1. A method of forming an electrically and/or thermally conductive polymer composite, comprising: mixing a polymer, a conductive particulate filler, and a solvent compatible with the polymer to form a non-conductive polymer solution or melt; wherein the conductive particulate filler is electrically conductive, thermally conductive, or both; wherein the amount of conductive particulate filler in the non-conductive polymer solution or melt is below the mechanical percolation threshold and the electrical/thermal percolation threshold of the conductive particulate filler therein; processing the non-conductive polymer solution or melt to form a non-conductive polymer network composition, wherein the polymers in said non-conductive polymer network composition are physically cross linked or a combination of physically and chemically cross linked; retaining said solvent to adjust a structure of the polymer network and the mechanical properties of said electrically and/or thermally conductive polymer formed through curing; and finally removing said solvent from the non-conductive polymer network composition to concentrate the polymers therein and the conductive particulate filler therein to form an electrically and/or thermally conductive polymer composite.
