Abstract: 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.

Abstract: Ionic solids, ceramics and most polymers and plastics are insulators, they do not conduct electrical current. Plastics are materials that can be formed into various shapes by the application of pressure or heat. Plastics are classified into thermosetting plastics, thermoplastic material, or an elastomer. A thermosetting plastic cannot be reshaped readily as it’s made from an irreversible reaction. Thermoplastic materials can be reshaped, for example polyethylene polymer used in the making of milk containers. Elastomers are plastics with elastic behavior or rubbery plastics, as they can be subject to stretching and bending. Polymers can be either naturally occurring from animals or plants or synthesized in chemical plants or chemical laboratories. This work is aimed to identify the polymers that are used in the textile industry and the polymers used as fill in materials in the construction industry, to find polymers that are less toxic with similar properties as PVC in the textile industry due to the environmental concerns that comes with using PVC, to know whether poly vinyl chloride is still used in the textile industry in the United States, and to find suitable polymers used as fill material in the construction industry.
