Here, we report for the first time the use of poly(3,4-propylenedioxythiophene) as platform for surface post-functionalization using the Staudinger-Vilarrasa reaction in order to covalently link perfluorinated chains and obtain various hydrophobic/oleophobic properties. 3,4-propylenedioxythiophene with one or two azido groups are prepared, in order to determine the impact of the number of functional groups on the surface morphology and wettability. Here, we show the possibility to prepare parahydrophobic (high water adhesion) or superhydrophobic (low water adhesion) surfaces with highly oleophilic to highly oleophobic properties.
