纳米纤维素/MXene多功能电磁干扰屏蔽复合材料的研究进展OA北大核心

Electromagnetic Interference(EMI)shielding materials are particularly important in an increasingly electromagnetic-inten-sive environment.Nanocellulose has low density,excellent mechanical properties,high structural stability,and thermal stability.MXene has high metallic conductivity,high aspect ratio,large specific surface area,and excellent electrochemical properties.Combi-nation of nanocellulose and MXene can be used to prepare high-performance EMI shielding composites.This paper discusseed the preparation methods of nanocellulose/MXene EMI shielding composites of different dimensions,including macro composite fibers,films and aerogels,and focused on the multifunctional applications of nanocellulose/MXene EMI shielding composites,including light-heat conversion,energy storage and flexible sensing.The development of nanocellulose/MXene multifunctional EMI shielding compos-ites was also prospeced.
