“…This type of research has come to be known as biomimicry, as proposals mimic a certain behavior or property of a natural material, creature or phenomenon. Among these, the engineering of surfaces based on certain animals, such as the Namibia scarab beetle, has received growing interest [1][2][3][4][5][6]. This small creature manifests a unique, tailor-made shell with hydrophobic and hydrophilic properties that allow it to survive in a harsh, dry and water-scarce environment [1,2].…”

The study of SiO2 nanoparticles (NPs) and their corresponding surface modifications through octadecyltrichlorosilane (OTS) has attracted attention due to their self-cleaning, hydrophobic and superhydrophobic (SHPho) properties, which are desirable for water collection based on the dew condensation effect. Such properties have been addressed by different strategies, of which the development of hybrid superhydrophobic/hydrophilic (SHH) surfaces has shown great promise. In this research, the pairing of OTS-treated and untreated SiO2 NP layers deposited on clay substrates is investigated with the aim of exploring a hybrid SHH surface capable of enhancing dew yield behavior. Infrared analyses were conducted using FTIR to study the interaction between the clay substrate and the OTS-treated and untreated SiO2 NPs. The hybrid SHH surfaces were morphologically characterized, and contact angle (CA) measurements were performed to explore their wettability behavior. The developed hybrid SHH surfaces exhibited hydrophilic (HPhi)/SHPho properties with an improved dew yield performance. The results obtained in this article are of relevance to the development of water-harvesting devices based on hybrid SHH surfaces.

“…Some insect feathers are superhydrophobic [4]. According to these natural phenomena, people obtain new material that is beneficial to humans such as food packaging materials [5] and superhydrophobic or superhydrophilic fabrics [6]. At the same time, wettability plays a key role in petroleum exploitation [7], boiling [8], condensation [9], coating [10,11], material [12,13], inkjet printing [14,15].…”

Wettability plays a vital role in many fields. In this paper, the shortcomings of current experimental measurement of dynamic wetting characteristics are described. The dynamic wettability of droplets on the simplified triangular wave micro-structure surface is studied by volume of fluid method. The results are compared with the dynamic wettability of droplets on the smooth surface and the rectangular wave micro-structure surface. The results show the similarities and differences of the motion characteristics of droplets on smooth surface and different micro-structure surface. Under the action of volume force, the droplets are first deformed and then moved. The droplets move as a whole on the smooth surface. But the droplets partially slip on the micro-structure surface, and the threephase contact point on the left side does not move.

“…Yet, these are often ineffective against emergent pollutants such as microplastics or when dealing with small amounts of liquid. However, the latter case is crucial in research fields also related to the SDGs, such as energy, as well as in microfluidics, microbiology, food packaging, [6] or pharmacy to isolate and separate substances and/ or microorganisms from effluents. [7] In this context, the advance of systems for small volume liquid separation is an important issue in nanotechnology and science materials research.…”

Fabrication of tunable wetting surfaces is sought for the last years given its importance on energy, biomaterials and antimicrobials, water purification, microfluidics, and smart surfaces. Liquid management on surfaces mainly depends on the control at the micro‐ and nanoscale of both roughness and chemical composition. Herein, the combination of a soft‐template method and plasma‐enhanced chemical vapor deposition is presented for the synthesis of TiO2 nanofibers on porous substrates such as cellulose and stainless‐steel membranes. The protocol, carried out under mild conditions, produces 3D nanomembranes with superhydrophobicity and oleophilicity that are tested as microliter water/oil filters. Photoactivation of TiO2 by UV illumination provides a straightforward approach for wetting tunability that converts the surface into amphiphilic. A final chemical modification of the TiO2 nanofibers by embedding them in an elastomeric polymeric shell and by fluorine‐based grafting opens the path toward the formation of superomniphobic and self‐cleaning surfaces with long‐lasting lifetimes. Thus, a reliable procedure is demonstrated for the fabrication of TiO2 nanofibers, which allows the modification of porous supports and provides an innovative route for the development of 3D nanomembranes with under design wetting. This protocol is extendable to alternative metal oxides, metals, and core@shell nanoarchitectures with potential multifunctionalities.
