Regular-wrinkling tunable MXene lattice for electromagnetic interference shielding

Protecting sensitive equipment from electromagnetic radiation damage requires the development of high-performance electromagnetic interference shielding films. As the film thickness is reduced to micro/nano scales, electromagnetic interference shielding capability generally decreases rapidly due to the weaker reflection. As a result, enhanced electromagnetic interference shielding performance in sub-μm thin films remains as an unsolved challenge. Inspired by the naturally wrinkling of fruit skin, we propose a homogeneous strain strategy to achieve self-wrinkling-induced lattice-structured MXene by uniform polymer shrinkage due to dehydration. Uniform wrinkle amplitude can be tuned from 0.8 to 6 μm, which…
