Multifunctional electromagnetic interference shielding films comprised of multilayered thermoplastic polyurethane membrane and silver nanowire

A well-designed multilayered composite film with alternating thermoplastic polyurethane (TPU) nanofiber membranes and silver nanowire (AgNW) layers was fabricated by vacuum-assisted filtration. The continuous AgNW conductive layer and the sandwich structure facilitated electron transmission efficiency and electromagnetic (EM) wave dissipation through multiple reflections and resonance effect, which resulted in a high electromagnetic interference...
