Stretchable superlyophobic surfaces for nearly- lossless droplet transfer

Stretchable superlyophobic films based on ethylene-vinyl acetate (EVA) were fabricated, which possess excellent flexible, transparent, stretchable and adhesive characteristics. They can be decorated on various complex surfaces, and provide ordinary surfaces with universal omniphobic performances. Note that adhesion of the EVA superlyophobic film can also be tuned through stretching, we demonstrated the use of stretchable superlyophobic EVA as a novel droplet tweezer for nearly- lossless water as well as oil droplet transfer, which enables many potential applications as a surface microfluidic platform.
