Abstract
A composition is described which is prepared so that it has a low electrical resistivity so that it can be used in electrostatic discharge operations. The composition includes carbon-coated fibers. The fiber is characterized in that it is a Lewis base while the carbon powder is a Lewis acid. The carbon-coated fiber is held together with a binder (such as a latex or resin). The binder may be either neutral or acidic. A resin can also be used to prepare rigid electrostatic discharge objects. When a resin is used, the resin should also be neutral and preferably, is acidic.
