All-Biomass Nanocomposite Films via Facile and Sustainable Design Procedure for Thermal Management and Electromagnetic Interference Shielding.

ABSTRACT: Emphasizing sustainability and low-cost flexible films to overcome thermal accumulation and electromagnetic radiation pollution is an urgent need in response to the lightweight and integrated development of electronic devices. Herein, a fully biomass-derived nanocomposite film is proposed and fabricated by self-assembling nano carbon spheres (NCSs) and cellulose nanofibers (CNFs) through a simple and scalable vacuum-assisted filtration method. The results reveal that the development of ordered and graphitized structures of NCSs through high-temperature pyrolysis facilitates π-π stacking, interfacial adhesion, and the construction ofconductive networks in the NCSs/CNFs films (NCF). Among all the NCF samples, NCF 5:5 achieves a tensile strength of 41.74 MPa, in-plane thermal conductivity of
