“…Typical strategies inspired by the human skin include extrinsic and intrinsic (dynamic reversible noncovalent or covalent bonding). Among these strategies, dynamic noncovalent cross-links based on supramolecular associations such as hydrophobic interactions, hydrogen bonding, − host–guest interactions, and electrostatic interactions offer more variety and a more comprehensive range of properties. However, most self-healing polymers require external stimuli, for example, heat, solvent, and so on.…”

Two-dimensional transition metal carbides (Ti 3 C 2 T x MXene) have emerged as new candidates for applications in multifunctional devices owing to their outstanding performance. However, these electronic devices are easily disturbed by water, breakage, oxidation during use, and limited energy resources. To solve these problems, herein, inspired by nature, a novel superhydrophobic, healable photothermal deicing and photodetector (SHPP) with a "papillary structure" is successfully fabricated for the first time, by a simple layer-by-layer assembly spraying process with 0D/1D/2D nanomaterials. As a result, the superhydrophobic modified 2D MXene coating (FM coating) on the SHPP sensor exhibits outstanding self-cleaning, long-term durability (>20 days), as well as excellent photothermal deicing performances under near-infrared light. Meanwhile, the unique semiembedded nano-ZnO/1D silver nanowire supports the sensor with desirable photoelectric performance with UV light and a fast response time (∼1 s), and good cycle stability. Moreover, benefiting from the transparent self-healing substrate, the photothermal deicing and photodetector properties can be restored at room temperature. The bioinspired structures and function mechanisms offer SHPP sensors great potential for the utilization of clean light energy, sensing, self-cleaning, anti-icing, and so forth.
