“…Such electrodepositions have already been realized on gold plates in previous literature. [ 32 ] The morphologies showed cauliflowers structures more than nanofibers and in CH 2 Cl 2 + H 2 O, the cauliflowers bubbles exploded to form craters with reentering surfaces. The architecture of the electrodeposition depends therefore strongly on the nature of the substrate.…”

“…Thieno[3,4‐ b ]thiophen‐2‐ylmethanol (Thieno‐OH) was synthesized from 3,4‐dibromothiophene following a procedure already reported in the literature ( Scheme ).

“…Very recently, by a judicious choice in monomer and H 2 O content, the templateless electropolymerization process in organic solvent such as dichloromethane (CH 2 Cl 2 ) has been proposed as an efficient method to prepare extremely well‐controlled porous nanostructures such as vertically aligned nanotubes. [ 26–33 ] Trace H 2 O naturally present in solution are responsible for the formation of gas bubbles (O 2 and/or H 2 ). The method does not require any acid or surfactant but the monomer has to play the role of the surfactant in stabilizing gas bubbles during electropolymerization.…”

“…In the first one, substituted monomers of the thieno[3,4‐ b ]thiophene family are selected for their capacity to form nanotubular structures. [ 30–33 ] Three substituents of different hydrophobicity are chosen: pyrene, perfluorobutyl (C 4 F 9 ), and perfluorooctyl (C 8 F 17 ) chains. In the second strategy, a thieno[3,4‐ b ]thiophene monomer with a functional hydroxyl group (OH) is first electropolymerized before to graft perfluorinated chains by simple esterification reaction.…”

Creating homogeneous nanostructures of complex substrates such as meshes remains a real challenge for practical applications. Here, a templateless elecropolymerization method is used to create conducting polymer nanotubes. Using thieno[3,4‐b]thiophene‐based monomers, nanotubes are obtained especially using dichloromethane saturated in water (CH2Cl2 + H2O) in order to release a high amount of O2 and H2 bubbles. Two strategies are used by direct electropolymerization or posttreatment by simple esterification reaction. By direct electropolymerization, the surface morphology is highly dependent on the used monomer. By contrast, by posttreatment it is possible to obtain the same structure and to change the surface energy during the posttreatment. With the last strategy, it is possible to reach superhydrophobic mesh with ultra‐low water adhesion and high oleophobic properties, even with short fluorinated chains (C4F9).

Bio‐inspired by natural species and previous research works, nanotubes are prepared by soft‐template electropolymerization in micellar solution. Various thiophene‐based and carbazole‐based monomers are designed from a triphenylamine core. With one of the carbazole‐based monomers, which is fully conjugated and with a star‐like structure, gecko‐like surface structures are obtained even if the structure is not perfectly planar. Extremely long and densely packed‐microtubes are reached especially at constant potential. However, the surfaces are not both highly hydrophobic and with strong water adhesion, but are superhydrophilic. These wetting properties can be explained by a high surface energy (gSV) = 41.9 mN m‐1 compared to gecko foot even if the natural gecko feet are also chemically inhomogeneous, or by differences in the arrangement of the surface structures.

Influence of Polyfluorinated Side Chains and Soft‐Template Method on the Surface Morphologies and Hydrophobic Properties of Electrodeposited Films from Fluorene Bridged Dicarbazole Monomers

et al. 2022

This paper is dedicated to Carlos FungoA clear case of relationship between the monomer molecular structure and the capability of tuning the morphology of electrodeposited gas bubbles template polymer thin films is shown. To this end, a series of fluorene-bridged dicarbazole derivatives containing either linear or terminally branched polyfluorinated side chains connected to the fluorene subunit were synthesized and their electrochemical properties were investigated. The new compounds underwent electrochemical polymerization over indium tin oxide electrodes to give hydro-phobic films with nanostructural and morphological properties strongly dependent on the nature of the side chains. Gas bubbles templated electropolymerization was next achieved by the addition of tiny amounts of water to the monomer solutions, without using surfactants. Within the investigated set of molecules, the nanostructural properties of the soft-templated films obtained from monomers bearing linear side chains could be fine-tuned by adjusting electrochemical parameters, leading to superhydrophobic surfaces.
