The principle of the biomimetic hydrogel fiber composed pattern (IMAGE)
Caption
The hydrogel fibers printed on the glass are covered by partially crosslinked dangling chains, exhibiting great affinity toward water molecules. They act like the grooves on the integuments of lizards to collect droplets and their surface could form a hydration layer to mimic the mucus on the catfish skin to make droplet movement more smooth and quick.
