Conductivity study of stretch-oriented new polyacetylene

Oriented polyacetylene samples were synthetized and doped with iodine and FeCl₃. Their electric conductivity and anisotropy were measured within the temperature range 4-300 K. The results were described using the Ping Sheng model. It is concluded that the factors limiting the conductivity parallel and perpendicular to the stretching direction are the same and thus no interfibrillar conduction occurs. Some processes related to the mechanical stretching are discussed. © 1994 John Wiley & Sons, Inc.
