Novel Cellulosic Fiber Composites with Integrated Multi-Band Electromagnetic Interference Shielding and Energy Storage Functionalities

A mild 2,2,6,6-tetramethylpiperidine-1-oxide mediated modification system was applied to improve the reactivity and introduce porous structure of cellulose fiber skeleton. Composite exhibited highly efficient electromagnetic shielding interference performance (> 99.99%) over multi-band. Integrating energy storage, electromagnetic interference shielding, and structural design into bio-based materials.
