Absorption-Dominated Electromagnetic Interference Shielding via Dual-Gradient Functionalized Carbon Nanotube Composites

Electromagnetic interference (EMI) shielding materials with high efficiency and absorption-dominated performance are crucial for addressing the challenges posed by electromagnetic wave pollution in modern electronics. In this work, we developed a high-performance EMI shielding material by integrating functionalized CNTs (f-CNTs) into a dual gradient conductivity–porosity structure. The multilayer structure was fabricated using a facile hot-pressing method, enabling the combination of films with varying porosity and conductivity. This approach facilitates the scalable production of large-area shielding materials and allows for the customization of EMI shielding properties by adjusting the layer characteristics.…
