Abstract
A high-strength conductive polymer composite can be made by mixing a a granular polymer and a conductive material, and processing the mixture using angular extrusion.
Claims19
A method for producing a conductive polymer composite, comprising the steps of:
- combining a granular polymer and a conductive carbon material, where the proportion of carbon material to polymer is in the range of 0.002%-10% by weight;
- mixing the combined polymer and carbon material to form an unconsolidated polymer-carbon mixture;
- and
- performing angular extrusion on the unconsolidated polymer-carbon mixture, thereby forming a consolidated composition.
A method for producing a conductive polymer composite comprising the steps of:
- combining a granular polymer and a conductive carbon material, where the proportion of carbon material to polymer is in the range of 0.002%-10% by weight;
- mixing the combined polymer and carbon material to form an unconsolidated polymer-carbon mixture;
- dispersing the polymer-carbon mixture within a first channel of a die;
- and
- exposing the polymer-carbon mixture to pressure and shear as the mixture moves through a portion of the die that forms at least one strain-imposing feature, thereby forming a consolidated composition.
A conductive polymer composite comprising a network of conductive carbon material distributed within the grain boundaries of a consolidated, nanocrystalline ultra high molecular weight polyethylene, prepared by a process that includes angular extrusion.
A conductive polymer composite formed by combining a granular polymer and a conductive carbon material to make an unconsolidated polymer-carbon mixture, where the proportion of carbon material to polymer is in the range of 0.002%-10% by weight, and where the polymer-carbon mixture is consolidated by conducting a process of angular extrusion on the polymer-carbon mixture, thereby forming a consolidated composition.
