Abstract
Materials containing precursors to electrically conductive polymers and electrically conductive polymers are described which have a high degree of crystallinity. The high degree of crystallinity is achieved by preparing the materials under conditions which provide a high degree of mobility to the polymer molecules permitting them to associate with one another to form a crystalline state. High levels of electrical conductivity are achieved in the electrically conductive materials without stretch orienting the material. The enhanced electrical conductivity is isotropic as compared to a stretch oriental film which has isotropic electrical conductivity.
Claims5
A composition formed from an electrically conductive admixture having isotropic electrical conductivity comprising:
- an electrically conductive polymer;
- and
- a crystallinity enhancing plasticizer additive;
