Abstract
The invention provides a conductive, resin-based composition, which includes a resinous material, and a conductive filler dispersed therein. The conductive filler includes a first conductive filler component and a second conductive filler component. The particles of the first conductive filler component are harder than those of the second conductive filler component, when measured using the Mohs hardness scale. The composition is subjected to shear mixing forces which shearingly disperse the first and second conductive filler components throughout the resinous material in such a way that the particles of the second conductive filler component occupy the interstitial voids within the network of first conductive filler component particles contained in the resinous material and thereby enhance conductivity.
