摘要

Controlling the formation of surface nanostructures and nanotubes in particular is extremely important for various applications in electronic devices for energy systems, biosensing but also for the control of water adhesion. Here, we use a direct (without template) electropolymerization process to produce vertically aligned nanotubes. Different monomers are tested as well as different solvents, electrolytes and electrodeposition methods. We show that naphtho[2,3-b]thieno[3,4-e][1,4]dioxine (NaphDOT) is the best monomer to obtain these nanotubes while dichloromethane has to be used as solvent for their formation. The surfaces with nanotubes display both extremely high apparent contact angles (θ(w)=142.7°) and high water adhesion even if the nanotubes are made of intrinsically hydrophilic polymers and are not densely packed.Copyright © 2015 Elsevier Inc.
