抜粋

With the aim of providing an easy and versatile method for realizing conductive polymer surfaces with controlled micro and nano-scale topographical cues patterning, we deposited a ultra-thin film of the conductive polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) on a thermo-retractable polystyrene sheet. Biaxial and uniaxial micro and nano-wrinkles were formed with different features depending on clamping geometry during shrinking of the substrate upon heating. Homogeneous nano and micro-patterning of surface topography over large areas (several cm2) was obtained. The formed wrinkles were very robust and adhered strongly to the substrate because of their penetration into the soft substrate during the heat-shrink process. In the case of uniaxial wrinkles a very well aligned quasi-periodic structure is formed with different populations of wavelengths ranging from submicrometric to 10-20 μm, depending on PEDOT:PSS thickness. Surface topography, wrinkles amplitude and wavelength have been evaluated by means of SEM and AFM and the results have been related to sheet resistance as measured with a four point probe technique. The realized conductive surfaces can offer new opportunities in the field of cell stimulation and growth.
