High current density and drift velocity in templated conducting polymers

Conducting polymers prepared by a templated vapour phase polymerisation process involving solid phase transition metal complexes are found to produce polymers with charge carriers that exhibit maximum drift velocity in the range of 1m/s. This super-mobility seems to be related to a high degree of ordering in the materials as evidenced by the X-ray diffraction data.

This may result from a templated polymerisation process. The high mobility manifests itself as a capacity to sustain very high current densities (>10000A/cm2); such high current densities are of importance in thin film conductor applications.
