Ionic conductivity in polypyrrole–poly (vinyl acetate) films synthesized by chemical oxidative polymerization method

Electrical investigation of polythiophene–poly(vinyl acetate) composite films via VTF and impedance spectroscopy

“…Thus, the conductivity of the films can be tuned by changing the concentration of the dopant. A similar bell type variation of conductivity was reported for PPy-PVAc composite films [24].…”

Study of DC conductivity and relative magnetic permeability of nanoparticle NiZnFe2O4/PPy composites

“…It is electro-active and can act as an anion exchanger. During the synthesis of PPy, some dopant anions are incorporated into the structure of PPy to balance the positive charge developed on the oxidized polymer chain [16]. Generally, in polypyrrole the DC conductivity shows an exponential dependence on temperature [17] and it is attributed to the existence of an ionic dopant in the polymer, which results in a delocalization of the double bond electrons [18].…”

Studies on Fourier transform infrared spectroscopy, scanning electron microscope, and direct current conductivity of polyaniline doped zinc ferrite

“…2 The control of the conductivity of CPC is also interesting for applications including sensor, electrochromic devices, corrosion inhibitors, electrochemical actuators, electromagnetic shielding, polymeric batteries, etc. 3,4 The conductivity of these composites depends strongly on the nature and interaction of the filler with the polymeric matrix. Cobalt metal was selected as filler due to its interesting electric and magnetic properties, since it may exist in different structural forms i.e., tetrahedral, octahedral, and isolated forms.…”
