S. de P.  aScanning force spectroscopy as a tool to study pulsed direct current electrical conductivity of polyaniline.  c1999  aAn AFM has been used as an electrostatic force spectrometer to analyze forces generated in a polyaniline sample on application of a pulsed DC voltage over a wide frequency range. The results are typical of a disordered medium of dispersed conductive islands in an insulating disordered matrix generated by doping.  aMatéria Orgânica  aAFM  aPolímeros  aPolyaniline1 aMATTOSO, L.
