Publikováno v: European Polymer Journal. 110:76-84

In the aim to tune the surface nanostructures and the resulting surface hydrophobicity and water adhesion, we report the preparation of surfaces by electropolymerization of 3,4-ethylenedioxypyrrole (EDOP) and 3,4-propylenedioxypyrrole (ProDOP) with b

Publikováno v: Materials Today Chemistry. 17:100278

In this original work, we want to control the shape of the resulting porous structures by templateless electropolymerization, by adjusting the spacer (flexible alkyl chains or rigid aromatic groups) between thieno[3,4-b]thiophene and carbazole used a

Publikováno v: Progress in Organic Coatings. 138:105382

In this work, we investigate original thieno[3,4-b]thiophene monomers with polar carbamate linkers and various substituents and demonstrate the ability to prepare nanoporous structures via templateless, surfactant-free electropolymerization in organi
