Actuation and Charging Mechanisms of Thin PEDOT:PSS Films Probed by Electrochemical AFM and Impedance Spectroscopy

open access: yesJournal of Polymer Science, Volume 63, Issue 21, Page 4661-4672, 1 November 2025.
The actuation of thin films of PEDOT:PSS has been characterized by electrochemical AFM. A relative decrease in the actuation behavior in dependence of the film thickness has been observed. The underlying mechanisms have been elucidated by chronoamperometry and electrochemical impedance spectroscopy. The decreasing relative actuation is attributed to an

Impact of Sonication Treatment on Physicochemical Properties of Carbon Blacks and Pt/C Catalysts in Proton Exchange Membrane Fuel Cells

open access: yesParticle &Particle Systems Characterization, Volume 42, Issue 11, November 2025.
Here it is revealed how ultrasonic dispersion chemically and structurally alters Pt/C catalysts depending on carbon black type. While high surface area carbons remain stable, low and medium surface area carbons undergo oxidation, increasing charge‐transfer resistance and degrading fuel cell performance.
