Abstract
An enhanced conductivity nanocomposite having reduced conductivity path directionality dependence as a means for enhancing the electrical and thermal conductivity. The composition comprises a synergistic blend of metal (and their derivatives) and carbon (preferably nanotubes) powder both average particle sizes in the nanometer to micron size range. The carrier medium is selected from the group of interpolymers, polymers, gaseous and liquid fluids, and phase change materials. The synergistic nanocomposite, when mixed with a conductive medium, exhibits enhanced heat transfer capacity, and electrical and thermal conductivity, stable chemical composition, faster heat transfer rates, and dispersion maintenance which are beneficial to most thermal or electrical transfer systems.
