An Electric‐Magnetic Dual‐Gradient Composite Film Comprising MXene, Hollow Fe 3 O 4 , and Bacterial Cellulose for High‐Performance EMI Shielding and Infrared Camouflage
Nanjing University of Aeronautics and Astronautics
Abstract
Abstract It is crucial to develop electromagnetic interference (EMI) shielding materials with high shielding efficiency (SE) and reduced reflection to mitigate the secondary pollution caused by electromagnetic waves (EMWs). Herein, a novel multilayer assembly strategy inspired by the structure of “Turkish dessert—Baklava” is proposed to introduce magnetic hollow Fe 3 O 4 nanospheres (HFO) and conductive MXene nanosheets into a bacterial cellulose (BC) network. Through a layer‐by‐layer vacuum filtration approach, a composite BC/MXene/HFO film with a controllable electric‐magnetic dual‐gradient structure is achieved. The construction of electric‐magnetic dual gradients alleviates the impedance mismatch at the…
