| Abstract: |
| In order to explore the effect of antioxidant on the dielectric properties of polypyrrole composite, with pyrrole as monomer, polypyrrole coating composite material was prepared by in-situ polymerization. The influence of the type and the concentration of oxidant oxidant on the dielectric constant, dielectric loss, and surface resistance of composite material were studied by using BDS50 dielectric spectrometer. Outer appearance, and strength were analyzed by using Quanta200 environmental scanning electron microscope and Instron universal material testing machine, respectively. The results showed that the type and concentration of oxidant exert a crucial role on dielectric constant, dielectric loss, and surface resistance of coating composite material. The obtained polypyrrole coating compsite material exhibits excellent performance on dielectric property, conductivity, and strength.
