Abstract
An electrically conductive polymer compound is disclosed. The compound comprises a matrix comprising polyphenylene sulfide and carbon nanotubes and glass fibers dispersed in the matrix. The carbon nanotubes are disaggregated and disagglomerated within the polyphenylene sulfide, when the compound is viewed at 20,000× magnification. The compound is useful for making extruded or molded plastic articles that need electrical properties.
Claims10
An electrically conductive thermoplastic compound, comprising
- (a) polyphenylene sulfide;
- (b) glass fibers;
- and
- (c) carbon nanotubes dispersed in an amount ranging from about 0.1 to about 10 weight percent of the compound in the polyphenylene sulfide, without aggregation or agglomeration of nanotubes in the polyphenylene sulfide when the compound is viewed at 20,000× magnification, wherein the compound has a specific gravity of at least about 1.5.
