Abstract |
Hyperbranched polymers are highly branched three-dimensional macromolecules. They have received attention due to their chemical and physical properties as well as their potential applications in coatings, additives, drug and gene delivery, macromolecular building blocks, nanotechnology, and supramolecular science. Diverse synthesis strategies, from click polymerization to recently reported multicomponent reactions, give rise to diverse hyperbranched polymers with desired functional groups and structures.
Electrochemical polymerization occurs by applying an electrical current through electrodes placed into the solution that contains the monomer and electrically conductive solvent. The electrical current causes the oxidation/radical generation from the monomer that yields polymerization. The properties of the produced polymer are influenced by the deposition charge and time, temperature, solvent, and electrode configuration. One of the key advantages of electrochemical polymerization is that it allows direct deposition of polymer nanostructures onto metal electrodes in a simple and cost effective way.
Hyperbranched polymers were synthesized by electrochemical polymerization using various types of halogenated hydrocarbons. Their structures were studied using FTIR, XPS, GPC-MALS, and NMR spectroscopy. Their synthesis and properties will be described. This research was supported by the Institute for Basic Science (IBS-R019-D1).
