Abstract

We report the self-running off phenomenon of microdroplet on strong water-spreading surface without any tilted degree actuation. It is found that when water droplet is deposited continuously gently on the porous superhydrophilic surface, the first droplet can spread strongly out in not more than 350 ms, while the subsequent droplet will run rapidly off the surface in 60-120 ms, in the absence of any tilted degree. It displays the more extreme "water repellency" than that of lotus leave or artificial superhydrophobic surfaces. This finding exhibits a unique way to design the antiadhesive surface using hydrophilic material.
