title: Conductivity Enhancement of PEDOT:PSS Films Through the Surface Treatment with Organic Solvent.
abstract: The improvement of conductivity is a key factor in application of conducting polymer to elec- tronic devices. The conductivity enhancement of
  PSS films were observed after dipping in polar organic solvents, including DMSO, ethylene glycol, glycerol and IPA. The conductivity of
  PSS films increased from 0.5 S/cm to over 800 S/cm, that is, by a factor of more than 1,600. The conductivity enhancement was dependent on the type of organic solvents and dipping time of
  PSS into solvent. The enhancement of conductivity may be caused by the phase separation between PEDOT chains and PSS counter anions.
