Superamphiphobic surfaces with extreme repellency toward both water and
oily liquids have been developed from various nanocomposites with
fluorinated compounds. However, the inherent rigidity and
low-surface-energy of these composites restrict their adhesion and
practical application in adjusting the surface wettabilities of
materials. Here we report a strategy to create hybrid superamphiphobic
coating with rapid contact adhesion to various kinds of substrates,
strong and controllable adhesive strength, unprecedented capability of
mechanical deformations, facile removal, repeatable adhesion, and simple
recyclization. Our approach, inspired by snail's ideal combination of
hard shell and soft epiphragm, is versatile and industrially-viable
because we use the hydrogel primer to bond the fluorinated nanoparticle
finish and substrates. Considering the unique characteristics of these
coatings as well as the wide range of available hydrogels and
nanomaterials that can be used via this approach, we envision that this
snail-inspired strategy will facilitate the development and large-scale
production of superamphiphobic coatings.
