“…During electropolymerization and depending on the electropolymerization method, different gases (dioxygen O 2 and hydrogen H 2 ) can be generated in-situ from H 2 O, and leading to various nanotubular structures. However, most of the monomers being not soluble in H 2 O, this strategy has been also envisaged in organic solvents such dichloromethane (CH 2 Cl 2 ) or chlo-roform (CHCl 3 ) [22][23][24][25][26][27][28].…”

Preparing well-ordered nanotubes on materials surface is a great of interest in many applications. Bio-inspired and theoretical approaches show that porous structures such as nanotubes are key parameters for both surface hydrophobicity and water adhesion. Here, a very easy soft-template electropolymerization approach is used to form nanotubular structures, followed by a bioinspired strategy to control the wetting properties. Fully conjugated monomers based on 3,4-(2,3- naphtylenedioxy)thiophene (NaphDOT) core grafted with many rigid aromatic groups such as phenyl, naphthalene, pyrene, pyrrole, were synthesized. Then, electropolymerization is carried out with these monomers, followed by surface and morphologies characterization of corresponding polymers. We show that even if just dimers are formed by electropolymerization, the resulting polymer can be sufficiently insoluble to form structured films. 3,4-(2,3-naphtylenedioxy)thiophene (NaphDOT) is chosen as a judicious example, due to strong π-stacking interactions, and also their capacity to form nanotubular structures by soft template-electropolymerization in the presence of water (H2O). Here, different substituents, polymerizable or not, are grafted on the 2-position of thiophene. Films are formed with all the studied substituents. Nanotubular structures are especially observed with the following substituents: hydroxyl, pyrene and pyrrole, but in the presence of H2O. We study also their influence on the surface hydrophobicity.

“…For instance, certain porous materials, such as anodized aluminum oxide or copper membranes, are common hard templates for electrodeposited nanotubes or nanowires Kawamura et al, 2014). Soft templating in electrochemicalbased synthesis has been explored in several materials as an improved method for obtaining 3D-ordered catalysts (Attard et al, 1997;Zhu et al, 2015;Li et al, 2018;Shi et al, 2021;Zhang et al, 2021;Fradin et al, 2022).…”

The current challenges in developing novel nanotechnological processes have led us to explore new methods for synthesizing nanomaterials whose functionalities rely on their structural complexity. In this respect, nature has always been a source of inspiration for proposing innovative technologies to improve the quality of life. Hierarchical superstructures (HSS) are of great interest because the self-assembly of low-dimensional nanostructures (up to the macroscale) allows the control and optimization of performance by coupling the properties of the individual blocks. Self-assembled surfactant structures are convenient for HSS synthesis because they provide a confined reaction medium which confers excellent control over the size of the building blocks. Furthermore, bicontinuous microemulsions offer a soft three-dimensional template due to their interconnected nature. Similarly, electrodeposition routes offer fast, robust, clean, and reproducible ways to synthesize metallic and multimetallic HSS. The combination of soft-templating and electrodeposition is a powerful tool for controlling the morphology and composition of the material. This work reviews polymeric, ceramic, and metallic hierarchical superstructures synthesized using bicontinuous microemulsions and electrodeposition techniques and compares them with matching natural patterns. The aim is to show how these synthetic routes can be exploited to obtain efficient biomimetic nanomaterials that improve their properties.
