Description
Summary:Bioinspired by the strong water adhesion of gecko foot or rose 1 petals, surfaces with nanotubes are prepared by soft-template 2 electropolymerization. A solvent a low water-solubility 3 (dichloromethane) is used with water to form a micellar solution 4 stabilized by a surfactant. Fully-conjugated monomers are 5 prepared by grafting thiophene and carbazole-based molecules to 6 naphthalene for favoring deposition vs polymerization as 7 confirming here by electrochemical characterizations. The water 8 content is fundamental for the formation of nanotubes. The 9 monomer has a huge influence on the surface structures even if 10 just the position of the substituent changes (ortho, meta, para). 11 Extremely long nanotubes are obtained with carbazole in meta-12 position indicating the deposition is highly favored in one 13 direction. The surfaces with both nanotubes and nanoparticles 14 display the highest hydrophobicity, combined with strong water 15 adhesion. Such surfaces could be used in the future for instance in 16 water-harvesting systems, sensing platforms as well as opto-17 electronic devices.
