Synthesis, Structure and Performance of Soluble Polyaniline by CPO-catalyzed Oxidation Using Small Molecule as Dopant or Polyelectrolyte as Template
摘要
Abstract
A green enzymatic approach for the synthesis of soluble polyaniline ( PANI) from p-phenylene diamine(PPD) monomer by chloroperoxidase ( CPO)-catalyzed H2O2-oxidation was proposed. The performance of aim product was improved compared to that of eigenstate polymer by the introduction of small molecule as dopant or polyelectrolyte as template, which was testified by UV-Vis spectra, cyclic voltammetry curve, electron microscope scanning, thermal gravimetric analysis and conductivity measurement. Sodium perchlorate was screened as the most effective dopant, and the corresponding product when n(PPD): n(NaC104)= 1 : 1 had fine layer structure and strong reversible redox capacity; The PANI obtained with polystyrene sulfonate(SPS) as the template had the best thermal stability and solubility as well as maximum conductivity. The enzymatic polymerization was analyzed according to the structure of active site in CPO.关键词
