Abstract
AbstractWith the advent of 5G and the Internet of Things (IoT), there is a high demand for lightweight and flexible electromagnetic interference (EMI) shielding membranes with multifunctional capabilities. However, the rapid advancement of technology has led to environmental deterioration, emphasizing the significance of eco‐friendly and sustainable materials for EMI shielding. In this study, a novel environment‐friendly EMI shielding membrane with electric thermotherapy function and antibacterial properties is developed. The membrane substrate utilizes recycled polyethylene terephthalate (rPET) and is sequentially coated with synthesized FeCo@C nanoparticles (NPs) and silver nanowires (Ag NWs). The membrane is then dip‐coated with PDMS to modify the surface superhydrophobicity. Experimental results affirm that the developed environment‐friendly EMI shielding membrane possesses exceptional shielding efficiency (68 dB) and can be effectively utilized for safe and low‐voltage thermotherapy (137 °C by 2 V) while exhibiting antibacterial properties.
