MethodMaterials Science Research

ProcedureA 'three-in-one' design approach was used to create a composite material by interweaving carbon fibers (CF), polyaniline (PANI), and silver nanowires (Ag NWs) with a 'branch-trunk' micro/nanostructure. This involved using polydopamine (PDA) to bond PANI branches to CF trunks, forming an interlocked structure. The resulting flexible composite was then evaluated for its mechanical properties, thermal insulation, heat preservation, EMI shielding, and Joule heating performance.
