TL;DR: This coating had a high surface mechanical strength and retained superhydrophobicity after blade scratch for several times or sandpaper abrasion for 20 m distance and was expected to be applied on roads, buildings, bridges, and many other concrete-based facilities in large scale for anti-icing and anti-corrosion purposes.

TL;DR: Rationally design MOFs derived NiCo-layered double-hydroxide (NiCo-LDH) and nitrogen-doped carbon nanosheets (NC) on the flexible carbon nanotubes (CNTs) film are rationally designed, both of which as the binder-free electrodes can greatly improve the specific surface area and reaction sites.
