Highly foldable PANi@CNTs/PU dielectric composites toward thin-film capacitor application

In this work, we synthesized a core-shell conductive filler of carbon nanotubes covered with polyaniline (PANi@CNTs), which showed good dispersibility to prepare highly flexible and foldable dielectric PMCs (PANi@CNTs/PU). The dielectric, mechanical, and thermal properties of the PANi@CNTs/PU composites were investigated. The mechanical flexible and foldable PANi@CNTs/PU composites could be promising dielectric material for preparing thin film capacitors.
