Summary: In this study, nanostructured conducting PEDOT:PSS thin films were prepared using solvent vapor annealing (SVA) with tetrahydrofuran (THF) as the low boiling point solvent. Atomic Force Microscopy (AFM) was used to observe the development of distinct nanostructures with solvent exposure time. The physical properties of the nanostructures were evaluated through nanomechanical, nanoelectrical, and nanoinfrared (nano-FTIR) measurements. It was demonstrated that exposure to THF can effectively and selectively modify the surface nanostructure of PEDOT:PSS and thus its final properties. The nanoscale studies also provided evidence of molecular rearrangements during nanostructure fabrication, which is crucial for expanding the potential applications of this polymer in thermoelectric and optoelectronic devices.
