Study Findings from Deutsches Elektronen-Synchrotron Provide New Insights into Organic Electronics (Molecular Reorientation and Structural Changes in Cosolvent-Treated Highly Conductive PEDOT:PSS Electrodes for Flexible Indium Tin Oxide-Free ...)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Researchers detail new data in Organic Electronics. According to news reporting from Hamburg, Germany, by VerticalNews journalists, research stated, "Cosolvent addition of glycerol (G) and the use of the cosolvent ethylene glycol (EG) increase the conductivity of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films to values on the order of indium tin oxide conductivity."

The news correspondents obtained a quote from the research from Deutsches Elektronen-Synchrotron, "The underlying morphological changes are probed via scanning electron microscopy as well as advanced scattering techniques microfocused grazing incidence small- and wide-angle Xray scattering, The enhancement in conductivity is ascribed to fundamental morphological changes and molecular reorientation within crystalline domains. Thereby, the conductivity enhancement is directly correlated to domain ruptures toward smaller and more densely packed PEDOT domains together with an enhanced crystallinity, the removal of PSS molecules, and moreover a reorientation of the conjugated PEDOT molecules."

According to the news reporters, the research concluded: "The latter is reported and quantified here for PEDOT:PSS films for the first time."
