Synthesis and Properties of Electroactive Hyperbranched Polymer

We prepared an electroactive hyperbranched polymer containing phenyl-capped aniline tetramer segment in the chains by integration of A2+B3 strategy with oxidative coupling polymerization.The structure of hyperbranched polymer was characterized by FTIR,~1H NMR spectra,and gel permeation chromatography(GPC).A reversible electrochemical property like common oligoanilines was found.The thermal properties and dielectric properties were also investigated.With an exciting structure,reversible electrochemical properties and dielectric properties,the electroactive hyperbranched polymer would be used as electromagnetic interference(EMI) shielding and microwave absorbing materials in the future.
