Abstract

Micro droplet handling is very important for micro and nano fluidic devices and an intelligent bio interface. Micro droplet transfer via high adhesion superhydrophobic surfaces has been reported in recent years. We demonstrated water droplet adhesion controllable superhydrophobic metal-polymer surfaces. Moreover we achieved micro droplet transfer between superhydrophobic surfaces by using different droplet adhesion properties. Water micro droplets were transferred from a low-adhesive superhydrophobic surface to a middle-adhesive superhydrophobic surface via a high-adhesive superhydrophobic surface without any mass loss. After transferred droplet possessed high water contact angle over 150 degrees. These moving processes were performed repeatedly. Droplet handlings on the adhesion superhydrophobic surfaces will be expected for fluidic bio devises with energy saving.
