Optical, electrical and ESR characterization of poly(p-phenylenesulfide) during electrochemical doping
No full textElectrochemical doping of poly(p-phenylenesulfide) (pPPS) in concentrated sulfuric acid offers a promising way for studying electrical properties of this material because an accurate control of the doping level is possible. We have performed an extensive investigation of the electrochemical behaviour of pPPS in 96% H2SO4 and, hence, measured in situ optical spectra, conductivity and ESR data of samples at different values of the injected charge; in this paper the results are presented and discussed in relation to data of pPPS and oligomers chemically doped
Electrochemical doping of poly(p-phenylene sulfide) in concentrated sulfuric acid
No full textThis paper deals with the electrochemical doping of poly(p-phenylene sulfide) in concentrated sulfuric acid. Cyclic voltammetry curves, as well as cyclic voltabsorptiometry curves and electronic spectra at different values of injected charge, are reported. The electronic spectra are discussed in relation to those of chemically-doped pPPS. © 1992
