摘要：The investigation of absorption-led shielding mechanisms has now made practical progress as a result of the concept of green EM shielding. The extant studies primarily concentrate on the introduction of magnetic particles into the system, with the objective of enhancing the absorption rate ( A ) through dielectricmagnetic modulation for absorption-led electromagnetic shielding. In contrast, this paper presents a novel approach whereby PVA, glycerol, and MXene are combined into an organohydrogel (PMG) with oriented pores. This results in the creation of a non-magnetic medium that exhibits high absorption loss in multiple bands, thereby establishing a novel shielding system. The PMG20-3 organohydrogel (0.78 wt % MXene) has a shielding performance in the X-band of 42.34 dB ( A / R = 1). In the terahertz band, the organic hydrogel gel exhibits an absorption rate of 99.9 %, a performance that exceeds that of the majority of previously reported systems. The PMG gel displays remarkable flexibility and strength, with a hysteresis return line that remains stable under 10 0 0 compression cycles. Additionally, it offers versatile sensing capabilities and infrared stealth. The findings of this study offer novel insights that may facilitate the accelerated utilization of innovative multifunctional and environmentally conscious electromagnetic interference (EMI) shielding materials.
