초록

내용
Super-foldable electronic materials enable numerous and scatheless folding are crucial for further development of flexible electronics, but often plagued by proper structural design for stress dispersion. We have created a super-foldable C-web/FeOOH-nanocone composite inspired by superflexible property of cuit cocoons and reversible unscathed folding of Mimosa leaves. It has cone-array on fiber structures like Mimosa leaves, as well as non-crosslinked junctions, slidable nanofibers, separable layers, and a compressible network as cuit cocoons, endowing it with over 100,000 times true-folding ability without any structural damage or conductivity degradation. Real-time SEM folding observation and finite-element simulations reveal a self-adaptive stress-dispersion mechanism from a two-level biomimetic design. Notably, SFCFe can serve as a high-performance super-foldable anode electrode for aqueous batteries, showing consistent CV and GCD curves during 100,000 true-folding times. The mechanism can guide more similar materials.
