Type: conference-paper
Abstract: Electric field manipulates the change of droplets wettability on superhydrophobic surfaces, which is widely used in many fields such as electronic zoom microlens and electro wetting displays, and has an important research value. This paper prepared a superhydrophobic acetate film applied electrostatic spinning technique,the maximum contact angle of acetate film is 152.6°, conducted electric field-regulated water droplet wettability change tests, applied voltage to water droplets on acetate film. it was found that the contact angle of the droplets decreased with the increase of the electric field strength, and the electric field regulated the contact angle of the droplets to change in the range of 92.7-142.3°. When the power supply is turned off, the contact angle of the droplet can gradually recover, but not completely restored to the original state.
