Intercalated Graphite Fiber Conductor.

Abstract

Lightweight electrical conductors were developed from graphitic fibers intercalated with highly electrophilic intercalants. Conductance increases of 30-36 times over the unintercalated fibers were observed. This corresponds to about 45% of the specific conductivity of copper at room temperature. Unlike copper, the intercalated graphite fibers exhibit a nearly zero temperature coefficient of conductance. The intercalated yarn did not change its resistance during 100 hours of passage of current at 1 watt power dissipation and current densities of 25-35 A/mm squared. Four graphite 'wires,' equivalent in size to 17-20 AWG copper wire were delivered. (Author)
