“…Polymer materials 12–16 are more lightweight, flexible, easy to process, and have excellent corrosion resistance. However, most of the polymer materials are non-conductive, and it is difficult to achieve high conductivity even with the addition of carbon nanotubes, 17,18 carbon fibers, 19,20 graphene 21–24 and other conductive fillers. Therefore, the combination of electrical conductivity and thermal conductivity of the material with light weight, easy processing, and excellent anti-corrosion performance is a competitive research direction.…”
