Triboelectric ‘electrostatic tweezers’ for manipulating droplets on lubricated slippery surfaces prepared by femtosecond laser processing

Abstract

Highlight Nepenthes-inspired lubricated slippery surfaces are prepared by a femtosecond laser. Droplet on the slippery surface can be manipulated by triboelectric charged rod. (3) Electrostatic tweezer is designed for achieving multifunctional droplet manipulation. Electrostatic tweezer enables manipulate droplets under diverse conditions. Various droplet-related applications can be achieved with electrostatic tweezer.
