Magneto resistance of polyacetylene nanofibers

Abstract

The magneto resistance (MR) of polyacetylene nanofibers is reviewed in this tutorial review. Earlier MR results on film types of polyacetylene and other conducting polymers are summarized first and then recent progress on the synthesis and characterization of conducting polymer nanofibers and tubes are surveyed. The studies on the dispersion and the MR measurements as well as the recent discovery of the vanishing magneto resistance (VMR) of polyacetylene nanofibers in high electric fields are reviewed. Comparing with the MR of polyaniline nanofibers, the deconfinement conduction of spinless charged solitons is introduced to understand the VMR of polyacetylene nanofibers in high electric fields.
