Stimuli-Responsive MXene/PNIPAM Hydrogel WITH High-Performance and Tunable Electromagnetic Interference Shielding Performance.

ABSTRACT: Smart electromagnetic interference (EMI) shielding materials capable of reversible EMI response hold great promise for application in flexible electromagnetic devices. Here, PPM hydrogels composed of poly (N-isopropylacrylamide) (PNIPAM) and MXene/PEDOT: PSS hybrid fillers are fabricated via ice-templated freeze-in-situ polymerization. The anisotropic structural design of the hydrogel enhances its mechanical properties, conductivity, and EMI shielding properties in a specific direction. Furthermore, it can rapidly adjust its internal water content under thermal and light stimulation. The EMI shielding performance of PPM hydrogels can transition from an EMI shielding status (EMI shielding on, >50 dB) to an EM-wave-transparent status (EMI shielding off, ≈2 dB) in the X-band with the dynamic
