Polymers may also have conductivities corresponding to those of semiconductors. ... The conductivity is about one million times greater in the plane of the graphite rings than at right angles to this plane: (parallel)/(perpendicular) = 106 . Correspondingly, the conductivity of stretchoriented polyacetylene is some 100 times higher in the stretch direction than perpendicular to it. ...
