Conductivity Switching Effect in Nanofiber Composites Modified with Conducting Polymer

Fibrous materials based on polyvinylidene fluoride and trifluoroethylene copolymers have been obtained by blend electrospinning and modified with polyconjugated polymer polypyrrole. The composite structure formed is a dielectric fiber in a conductive shell. The results indicate that by varying the degree of polypyrrole doping-up it is possible to change the character of the conductivity of the composite reversibly from inductive to capacitive.
