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.

Electrospinning has rapidly progressed over the past few decades as an easy and versatile way to fabricate fibers with diameters ranging from micrometers to tens of nanometers that present unique and intricate morphologies. This has led to the conception of new technologies and diverse methods that exploit the basic electrohydrodynamic phenomena of the electrospinning process, which has in turn led to the invention of novel apparatuses that have reshaped the field. Research on revamping conventional electrospinning has principally focused on achieving three key objectives: upscaling the process while retaining consistent morphological traits, developing 3D nanofibrous macrostructures, and formulating novel fiber configurations. This review introduces an extensive group of diverse electrospinning techniques and presents a comperative study based on the apparatus type and output. Then, each process's advantages and limitations are critically assessed to identify the bona fide practicability and relevance of each technological breakthrough. Finally, the outlook on future developments of advanced electrospinning technologies is outlined, with an emphasis on upscaling, translational research, sustainable manufacturing and prospective solutions to current shortcomings.

Photothermal materials that can convert solar energy into heat energy through photothermal conversion have attracted extensive attention, but these materials are easily polluted by the environment. Here, we propose a simple and effective strategy for constructing photothermal superhydrophobic cotton fabrics with self-cleaning ability. The PDA@PEI@GA@Ag@ PDMS-coated cotton fabric can achieve good superhydrophobicity (water contact angle: 159.6°) by a simple dipping method and mussel-inspired dopamine surface modification, which is regulated by the mass of dopamine, the mass of silver nitrate, and the concentration of polydimethylsiloxane (PDMS). The coated cotton fabric has good physical and chemical stability. Meanwhile, the coated cotton fabric has excellent self-cleaning and antifouling properties. The superhydrophobic PDA@PEI@GA@Ag@PDMS fabric exhibits excellent and stable photothermal properties, with the surface temperature reaching 70.4 °C under simulated sunlight with a current of 20 A. This photothermal superhydrophobic fabric with self-cleaning properties is expected to be applied in the field of photothermal conversion.
