“…The copper coil driven by RF power supply can generate large volume plasma which can charge 20 μm diameter median droplet efficiently. The optimal ASPD rate based on these charged droplets for the perfluorotributylamine precursor is about 49 � 4 nm min À 1 at a liquid flow rate of 16 � 4 � 10 À 4 ml s À 1 , while the atomized spray deposition without plasma is below 0.1 � 0.1 nm min À 1 [111]. Besides that, the charged drops of monomer produced by DBD electro-spray coating in air is also used for polymer coatings.…”

Recently, charged aerosols are used widely in many applications, such as fog elimination, inactivation of airborne viruses and so on. Atmospheric pressure nonequilibrium plasma (APNP) have become an efficient way to generate charged aerosols. Except the traditional pin-plate or wire-plate APNP sources, the new APNP sources such as large scale corona discharge system and air plasma jet array are introduced. These sources can increase the ion density in open air and generate adjustable large plasma plume, which are helpful in increasing the charging efficiency on aerosols. Although the interactions between plasma and aerosols is quite complicated, the preliminary study suggests that the diffusion charging dominates aerosols below 0.1 μm, field charging dominates aerosols larger than 1 μm, and the photo charging also contributes to aerosols charging. These reactive charged aerosols have shown their potential in the artificial rain enhancement, biomedicine, and material processing. Finally, challenges and opportunities for theoretical, experimental, and application research in related cross-disciplinary areas are presented to stimulate critical discussions and collaborations in the future.

“…Atomised spray plasma deposition (ASPD) based on perfluorotributylamine–nanoparticle slurry mixtures can generate super‐hydrophobic nanocomposite layers in a single solventless step [111]. ASPD is carried out in an electrodeless, cylindrical, T‐shape glass reactor enclose in a Faraday cage.…”

“…stability of such composites. For instance, in one previous report, [33] a poly(perfluorocarbon) matrix was used to provide a low bulk wettability, while graphene flakes increased the hardness above that of stainless steel, and atomized spray plasma roughened the surface to generate the lotus effect. In another report, [34] covalent integration of GO in a porous polymer matrix led to "internally" superhydrophobic monoliths and bulk coatings (Figure 2c) that were highly resistant to chemical attack and retained their properties even after the top layers were physically removed.…”

It can be difficult to know where to begin when considering the research opportunities of a material with such outstanding potential as graphene. When searching for a “killer application,” the researcher often neglects to query the world around them, forgetting that nature has been evolving for billions of years to elegantly solve every day problems. Bioinspiration is an intelligent strategy to nucleate new ideas and speed up the innovation process by providing ready‐made prototypes. Graphene is uniquely placed to take advantage of this approach thanks to its superlative properties and versatile nature. In this review, the state‐of‐the‐art in the bioinspired design of graphene‐based materials has been analyzed, and three distinct sources of inspiration have been identified: natural functions, such as adhesion and actuation; natural structures, such as layers and pores; and natural processes, such as surface functionalization and biomineralization. Implementing this philosophy into further graphene research will provide new ways to solve problems and suggest novel applications that may not otherwise be considered.

“…Thus, various techniques have been investigated to prepare superhydrophobic surfaces, including chemical etching, 5 , 6 laser processing, 7 , 8 layer-by-layer assembly, 9 , 10 the sol–gel method, 11 , 12 chemical vapor deposition, 13 , 14 and plasma processing. 15 , 16 Although these reported fabrication methods of superhydrophobic surfaces show excellent performance, toxic low-surface-energy materials are always used, such as fluorine-containing compounds. 17 – 19 In addition, ZnO, TiO 2 , and SiO 2 are widely used during the creation of the rough structure, which may threaten human health.…”

A novel fluorine-free and silicon-free superhydrophobic aluminum alloy (treated-Al) is fabricated by chemical etching using hydrochloric acid and hydrogen peroxide and modified with an organic carbon dot (OCD) coating. The water contact angle (CA) of the treated-Al surface increases with the OCD concentration. When etched aluminum (etched-Al) is modified with 0.5 mg/ml OCDs, a CA of 161.4°is achieved, which indicates good nonwettability. SEM results verify that porous microstructures with cavities are uniformly distributed on the surface of etched-Al, in contrast to the bare aluminum alloy, which forms a primary rough structure. After treatment with 0.5 mg/ ml OCDs, a nanoparticle coating is dispersed on the rough structures of treated-Al-0.5, which can trap air and make a water droplet essentially rest on a layer of air. The treated-Al-0.5 material has good self-cleaning properties and can sweep away contaminants at both 20 and 0°C. The Ecorr and Icorr of treated-Al-0.5 are À 0.56 V and 2.82 9 10 À6 A/cm 2 , respectively, which shows good anticorrosion performance.
