چکیده
The fast development of terahertz technologies demands high-performance electromagnetic interference (EMI) shielding materials to create safe environments. Despite tremendous breakthroughs in achieving superb efficiency (SE), conventional have high reflectivity and cannot be re-edited or recycled once formed, resulting detrimental secondary pollution poor adaptability. Herein, a hydrogel-type material incorporating MXene poly(acrylic acid) is fabricated through biomineralization-inspired assembly route. composite hydrogel exhibits excellent stretchability recyclability, favorable shape adaptability adhesiveness, self-healing capability, demonstrating great application flexibility reliability. More interestingly, the performance shows absorption-dominated feature due combination porous structure, moderate conductivity, internal water-rich environment. High EMI SE 45.3 dB broad effective absorption bandwidth (0.2-2.0 THz) with refection loss 23.2 can simultaneously achieved an extremely thin (0.13 mm). Furthermore, such demonstrates sensitive deformation responses used as on-skin sensor. This work provides not only alternative strategy for designing next-generation but also highly efficient convenient method fabricating on macroscopic scales.
