Perfluoro-functionalized PEDOT thin films with various surface morphologies were prepared electrochemically by applying different potential pulse sequences using ionic liquids as electrolyte and solvent, and these films could display superhydrophobicity with enhanced capability of cell adhesion.

We developed a novel approach for hydrophobic patterning: combining the photolithography technique with ionic-liquid (IL)-based electropolymerization to fabricate a hydrophobic pattern. Perfluoro-functionalized 3,4-ethylenedioxythiophene (EDOT-F) dispersed in ILs was directly electropolymerized on substrates, which were patterned in advance with positive photoresists. The positive photoresists did not dissolve in ionic liquids during the electropolymerization process, and the poly(EDOT-F) film created hydrophobic domains, which resulted in hydrophobic patterning.
