The increasing reliance on electronic devices has created a pressing demand for high-performance and sustainable electromagnetic interference shielding materials. While conventional materials, such as metals and carbon-based composites, offer excellent shielding capabilities, they are hindered by high costs, environmental concerns, and limitations in scalability. Polysaccharide-based materials, including cellulose, chitosan, and alginate, represent a promising alternative due to their biodegradability, renewability, and versatility. These materials, when combined with advanced fillers such as MXene, graphene, silver nanowires (AgNW), carbon nanotubes (CNTs), and magnetic nanoparticles like Fe
