In this study, PEDOT thin films polymerized with Iron(III)tosylate ($Fe(PTS)_3$) and grown on acetic acid-catalyzed 3-aminopropyltriethoxysilane self-assembled monolayer (APS-SAM) surfaces by VPP method have been investigated. PEDOT thin films were synthesized on APS self-assembled $SiO_2$ wafer surface at two different concentrations (20 wt% and 40 wt%) and growth time (3 and 30 minutes), and then they were compared. PEDOT vapour phase-polymerized with 40 wt% $Fe(PTS)_3$ oxidant completely formed a thin film on acetic acid-catalyzed APS-SAM surface while with 20 wt% $Fe(PTS)_3$ did not at all. It means that the oxidant can be uniformly coated on acetic acid-catalyzed APS-SAM surface at the 40 wt% concentration, which gives rise to the uniform growth of PEDOT thin film on it.
