Abstract
Carbon pitch-based fibres (P-120, Amoco) exhibit a 30-fold enhancement in conductivity upon intercalation with AsF5-a significantly larger value than the conductivity enhancement in the less ordered P-55, P-75 and P-100 fibres. The mechanism for the enhanced conductivity in these fibres is studied by using Raman, ESR and X-ray techniques. We demonstrate the existence of a relation between the conductivity enhancement and the degree of 'order' in the pristine fibres. The enhanced conductivity is explained by charge transfer and improved structural order upon intercalation.
