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.

Professor Suprakas Sinha Ray, born in 1973 in India, completed his Ph.D. at the University of Calcutta in 2001. He was a postdoctoral fellow at Toyota Technological Institute, Japan, and Laval University, Canada, researching nanoclay-polymer nanocomposites. He joined CSIR in October 2006 as a group leader and then became a chief researcher and the founding director of the DSTI-CSIR Nanotechnology Innovation Centre. His work has expanded to include more than 85 researchers, engineers, scientists, students, and industrial partners worldwide. He is a highly active author (h-factor 100, GC) in the field of polymer nanostructured materials, recently ranked in the Top 1% of impactful scientists across 22 disciplines by Thomson Reuters, and among the top 50 chemists globally in 2011. Prof. Ray has written 14 books, co-edited 9, authored 30 book chapters on polymer-based nanostructured materials, and published over 575 articles.
