Abstract
With the development of advanced communication systems, paralleled with recent efforts to adopt lightweight, low-carbon footprint materials, there is an urgent demand for green electromagnetic interference (EMI) shielding materials. However, this is challenged by the shielding effectiveness of bio-based EMI and their capacity to eliminate radiation pollution while meeting the demands of diverse application environments. Learning from the strategies used by epiphytes, we introduce a highly efficient and multi-functional bio-based EMI shielding eco-material. We developed 3D hybrid network structures incorporating coordination-driven silver nanoparticles to achieve excellent shielding effectiveness, ∼30.8 dB, while simultaneously meeting mechanical demands, multi-functionality, water resistance, flame retardancy, and antibacterial properties. Overall, this work provides a novel but practical pathway to implement bio-based materials conferred with EMI protection, applicable in next-generation electronics.Description
