Abstract
The invention provides semi-conductive, static dissipative polymeric composites comprising: PA1 a) an insulative polymeric resin, and PA1 b) from about 5 to about 35 volume percent of at least one high aspect ratio filler having a thin-film inorganic layer of from about 10 .ANG. to about 1000 .ANG. of a highly conductive metal and an overlayer of an insulative metal oxide, said layer having an average coating thickness of from about 2 .ANG. to about 200 .ANG., the composites having volume resistivities of from about 1.times.10.sup.4 ohm-cm to about 1.times.10.sup.11 ohm-cm.
