Superhydrophobic surfaces with microstructures and multifunctionality have attracted intense research interest. Herein, a multiscale microflower structured surface (MMSS) was successfully fabricated by electrostatic air spray. To systematically study the preparation process, the influences of different electrostatic voltages, solution ratios, soaking time, spray distances, and spray time on surface morphology and hydrophobicity were analyzed. The surface has good superhydrophobic properties with a water contact angle of 162.3°, which allows the surface to be selfcleaning and antifouling. The surface hydrophobicity can be maintained after various mechanical and chemical damages. To overcome the limitation that existing droplet manipulation relies on special materials and surfaces, a new and universal droplet transport method is presented to successfully perform nondestructive droplet manipulations, which relies on external forces and droplet deformation to drive droplets. Therefore, this paper represents a different approach from previous studies of superhydrophobic surfaces and provides a new way to achieve dynamic droplet manipulations. These results indicate that the multifunctional MMSS will be widely used in industrial droplet transportation and self-cleaning applications.

“…The nanoparticles sprayed on the substrate were dense and uniform in the ESD method, while rare and sparse in the air spray method. The attraction of opposite charges in the EASD method makes the negatively charged droplets attach firmly to the positively charged plate electrode. , This effectively prevents the liquid from dispersing in air, making it environment friendly.…”

A new method was reported for preparing a magnetically responsive superhydrophobic surface by electrostatic air spray deposition (EASD) and magnetic induction. The mixture was fully atomized under the combined action of the electrostatic field and the high-speed airflow field, and a dense array of micropillars was formed. The atomization mechanism of EASD was explored. The distribution and physical parameters of the micropillars were evaluated and counted. Switchable adhesion characteristics of the surface and the reversibility in 10 cycles were examined. The influences of different electrostatic voltages, component concentration, spray distance, air pressure, and magnetic field intensity on the surface morphology and hydrophobicity were analyzed. The prepared surface can be reversibly transformed between the high-adhesion state (with a contact angle of 108°) and the low-adhesion state (with a contact angle of 154°) by on/off switching of an external magnetic field. After a 2.2 kPa pressure load was applied, the surface contact angle was 144° with an applied magnetic field of 0.4 T. After heated at 90 °C for more than 90 min, the surface can almost obtain superhydrophobicity (with a contact angle of 148°) in the absence of a magnetic field. By utilizing the switchable surface adhesion characteristics, various kinds of droplet transmissions were realized. When the cured surface was spray-coated with carbon nanoparticles (CNPs), active droplet manipulation can be achieved by simply moving the magnet. The advantages of this method include a simple preparation process without chemical surface modification.
