While the development of polymer coatings with controlled surface topography is a growing research topic, a fabrication method that does not rely on lengthy processing times, bulk solvent solution, or secondary functionalization has yet to be identified. This study presents a facile, rapid, in situ method to develop parahydrophobic coatings...

To control the wettability of polymer interfaces with water without using perfluorinated chains, the 3,4-ethylenedioxythiophene (EDOT) monomer and its derivatives have been good candidates for surfaces formed by electrodeposition. In this work, a series of original EDOT-based monomers were studied. A carbamate linker was used to introduce alkyl...

The formation of porous nanostructures on surfaces and the control of their size and shape is fundamental for various applications. The creation of nanotubes is particularly difficult to implement without the aid of hard and rigid templates. Recently, methods that form nanotubular structures in a straightforward manner and without direct...

Surface post-functionalization is one of the key modification pathways leading to superhydrophobic surfaces. The functionalization is deeply linked to the functionalizable area and the number of functionalizable groups. By grafting functional nanoparticles onto surfaces it is possible to dramatically increase both the area and the number of...

Chitosan is a polymer obtained by deacetylation of chitin, and chitin is one of the major components of the arthropod cuticle. Chitin and chitosan are both polysaccharides and are considered to be an interesting class of biosourced materials. This is evident as chitosan has already demonstrated utility in various applications in both industrial...

In this work, novel 3,4-phenylenedioxythiophene (PhEDOT) monomers with alkyl, branched, and aromatic substituents were synthesized and tested for their efficacy at forming surfaces with unique wetting properties and surface morphology without the aid of surfactants. Monomers with a naphthalene substituent clearly showed the highest capacity to...

Here, a bioinspired strategy is used to prepare well-ordered nanotubular structures, as observed in animals and plants such as gecko toepads or corals. The nanotubes are obtained by templateless electropolymerization of thieno[3,4-b]thiophene-based monomers with various aromatic groups in organic solvent (dichloromethane). The most interesting...

In this work, we present the synthesis of original thieno[3,4-b]thiophene monomers with rigid substituents (e.g., perfluorinated chains, and aromatic groups) and demonstrate the ability to prepare nanotubular and nanoporous structures via templateless, surfactant-free electropolymerization in organic solvents (dichloromethane). For the majority...

Biopolymers and their derivatives are materials with increasing interest for industry and especially for sustainable engineering development. Among such kind of materials, carbohydrate polymer like highly deacetylated chitin (chitosan) is widely used for a wide range of applications, including material and biomedical developments. The majority...
