We report the influence of the substituent size and position of 3,4-propylenedioxythiophene on the surface properties of the corresponding electrodeposited polymer films. We study the influence on the formation of hydrophobic nanofibers using two substituents (isopropyl and tert-butyl). We show that the 3-position of ProDOT is the best for the formation of nanofibers, because it leads to the longest polymer chains while leading to the highest intrinsic hydrophobicity; two effects increasing the formation of surface structures.
