【 摘 要 】

We synthesized dodecyloxymethyl functionalized EDOT monomers and fabricated homogeneous thin films via cycle voltammetry electrochemical deposition method on platinum and ITO substrates. The PEDOT-C12 thin films showed good electrochemical activity. Meanwhile, by increasing the cyclic voltage-scan number during electrochemical deposition process, the surface roughness was also enhanced. The large surface roughness and occurrence of micro-nano surface morphologies would lead to higher water contact angles for the PEDOT-C12 thin films. The water contact angle for the PEDOT-C12 thin films with 10 deposition cyclic voltage-scans was 160° and showed superhydrophobicity. The achieved superhydrophobic PEDOT-C12 thin films would have potential applications in corrosion protecting for metal electrodes in aqueous environment.
