제목 Synthesis of Nanocomposite by Redox Reaction with Chloroauric acid and an Oligoaniline-Containing Polyurea
초록 The t-BOC (tert-butoxycarbonyl) protected aniline heptamer diamine with higher solubility and air-oxidation stability was synthesized with 1,12-diisocyanatododecane, resulting in a multi-block polymer containing oligoanilne blocks, which is poly (oligoaniline-dodecane-urea)[P(7OA-12DI)]. By addition of chloroauric acid(HAuCl4) into the solution of the polymer, we obtained gold nanoparticles that were uniformly dispersed in the solution according to redox reaction between HAuCl4 and an oligoaniline-containing polyurea. A uniform gold-polymer nanocomposite material was produced by casting the solution onto various substrates. The morphologies and structures of the products were investigated by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and UV-vis. spectroscopy. We study gold nanocomposites with multiblock polymer to develop nonvolatile memory device application.
