Effects of processing conditions on the electrical switching performance of nanoparticulate PEDOT composites showing large field-controlled impedance change

Composite materials containing nanoparticulate PEDOT in a polymer electrolyte matrix containing either a Cu–Cu2+ or Fe2+–Fe3+ redox couples show rapid and reversible decreases of up to 500-fold in their electrical and microwave impedances when small DC or AC electric fields are applied across coaxial line and strip samples from their edges, which are much larger than microparticulate PEDOT composites and make signification progress in this field. The composites show large field-dependent resistances at low applied fields and good electrochemical stability.
