Abstract

Compositing magnetic loss materials on biomass materials have been evolved as an effective pathway to satisfy the requirement of lightweight and high shielding effectiveness of electromagnetic functional materials. Here, a core–shell-like Ni-coated wood-derived porous carbon composite (Ni/WPC) with anisotropic porous architecture was demonstrated. The three-dimensional WPC structures not only act as the dielectric loss part but also establish a multiple scattering route to eliminate the incident EMW. The nickel-coated shells could serve as the magnetic loss part and meanwhile construct the interfacial polarization through the heterogeneous structures with the WPC skeleton. As a result, an excellent EMI shielding effectiveness of 34.1 dB with a thickness of 2 mm can be realized in Ni/WPC-30 at the X band. Additionally, the Ni/WPC composite possesses an extraordinary flame retardant property, exhibiting excellent service adaptability and which can be extended to other applications.
