Cellulose Conductive-Network Composites for Electromagnetic Interference Shielding

This book delivers a comprehensive, critical treatment of cellulose-based conductive composites for electromagnetic interference (EMI) shielding, from fundamental materials chemistry to advanced applications. It examines how processing methods, filler selection, and hierarchical conductive architectures govern electrical response, dielectric behavior, and shielding effectiveness. Special emphasis is placed on the role of nanocellulose, carbon nanomaterials, MXenes, metal nanoparticles, and conducting polymers in forming efficient percolated networks within sustainable cellulose matrices. Modern electronics demand lightweight, flexible, and sustainable materials capable of protecting devices and users from electromagnetic interference. Cellulose, an abundant and renewable biopolymer, has emerged as a powerful platform for next-generation EMI shielding when engineered into conductive-network composites. Beyond performance, the book integrates sustainability assessment, including life-cycle analysis, footprint metrics, and circular-economy considerations, providing an essential bridge between materials innovation and environmental responsibility. Emerging processing routes—such as the use of ionic liquids for cellulose dissolution—are presented as enabling technologies for scalable, high-performance, eco-friendly EMI shields. This book serves as a definitive reference for researchers, engineers, graduate students, and industrial R&D professionals working at the intersection of polymer science, electronics, materials engineering, and sustainability.
