An electrically conductive fibrous material and a process for preparing the same from a thermally stabilized acrylic fibrous material are provided. The thermally stabilized acrylic fibrous material is first contacted with cuprous ions to produce a cuprous ion-impregnated fibrous material, and subsequently is subjected to a sulfiding agent capable of sulfiding cuprous ions, and preferably washed, to produce thermally stabilized acrylic fibrous material having covellite copper sulfide in association therewith. Also provided are electrically conductive composites and a process for preparing the same by incorporating the fibrous material prepared in accordance with the process within a substantially continuous polymeric matrix.
A sheetlike article comprising thermally stabilized acrylic fibrous material associated with from about 5 to about 60 percent by weight of electrically conductive covellite copper sulfide, present in at least one layer comprising a multiplicity of said fibers and having a thickness of approximately 1 mil to 1 inch, said article having a sheet resistivity in the range of from about 0.1 to about 1000 ohms/square.
A monolithic electrically conductive composite article comprising electrically conductive thermally stabilized acrylic fibrous material in association with approximately 5 to 60 percent by weight of covellite copper sulfide based upon the total weight of the conductive fibrous product, surrounded with a substantially continuous resinous matrix.
A monolithic electrically conductive composite article comprising a fabric, paper or felt which includes thermally stabilized acrylic fibrous material in association with approximately 5 to 60 weight percent of covellite copper sulfide, said fabric, paper or felt being incorporated within a solid continuous polymeric matrix.
A monolithic electrically conductive composite article comprising thermally stabilized acrylic fibrous material in association with approximately 35 to 60 percent by weight of covellite copper sulfide incorporated within a solid continuous cured epoxy resin matrix.
A polymer composition suitable for use in electrically conductive end uses comprising electrically conductive thermally stabilized acrylic fibrous material in association with approximately 5 to 60 weight percent of covellite copper sulfide and a polymeric carrier.
