Abstract
Abstarct: —The impedance spectra of composite nonwoven materials based on nano- and microfibers of polyvinylidene fluoride copolymer with trifluoroethylene modified with polypyrrole with various degrees of doping are studied in the frequency range 1 × 103–1.5 × 107 Hz. It is found that an increase in the degree of doping of the polypyrrole coating of nanofibers leads to a decrease in the imaginary and real components of the electrical impedance. Regardless of their size, the shape of the hodographs is close to the arc of a circle based on the axis of the real component, which allows considering the studied material as a nanocomposite polymer electrolyte, the dielectric characteristics of which can be reversibly changed.
