“…As mentioned in section , the liquid bridges caused by superhydrophobic pillar-structured surfaces are easily broken due to their poor strength after solvent evaporation. For example, replacing the building blocks inside the liquid bridges using polymers − and/or organic-capped nanoparticles rather than inorganic salts can maintain the morphology of the liquid bridges, yielding regular 1D assemblies of these building blocks (Figure a). Because the position, alignment direction, and density of the liquid bridges are tunable, the rational design of a 1D assembly of diverse nanoscale building blocks, including organic molecules, nanoparticles, or graphene sheets, is easy.…”

Superwettability is a special case of the wetting phenomenon among liquids, gases, and solids. The superhydrophobic/superhydrophilic effect discovered initially has undergone a century of development based on materials science and biomimetics. With the rapid development of research on anti-wetting materials, superoleophobic/superoleophilic surfaces have been fabricated to repel organic liquids besides water. Further studies of underwater superoleophobic/superoleophilic/superaerophobic/superaerophilic materials provide an alternative way to fabricate anti-wetting surfaces rather than lowering the surface energy. Owing to a series of efforts on the studying of extreme wettabilities, a mature superwettability system gradually evolved and has since become a vibrant area of active research, covering topics of superhydrophobicity/superhydrophilicity, superoleophobicity/superoleophilicity in gas or under liquid, superaerophobicity/superaerophilicity under liquid, and combinations of these states. The kinetic study of the superwettability system includes statics and dynamics, while the studied material structures range from traditional two-dimensional materials to three-dimensional, one-dimensional, and zero-dimensional materials. Furthermore, the wetting liquids range from water to oil, aqueous solutions, and ionic liquids, as well as liquid crystals and other types of liquids. The wetting conditions extend over a wide range of temperatures, pressures, and other external fields. With the development of this series of research, many new theories and functional interfacial materials have been fabricated, including self-cleaning textiles, oil/water separation systems, and water collection systems, and some of these have already been applied in industry. Moreover, the study of superwettability has also introduced many new phenomena and principles to the field of interfacial chemistry that display its vast potential in both materials and chemistry. The present Perspective aims to summarize the most recent research on these materials and their interfacial chemistry. An overview of novel materials in superwettability systems and interfacial materials is presented. Specifically, the evolution of superwettable materials will be introduced, and the fundamental rules for building these superwetting materials will be discussed, followed by a summary of recent progress in the application of superwettable materials to alter the behaviors of chemical reactants and products. Specific emphasis is placed on recent strategies that exploit superwettable materials to influence the performance of traditional chemical reactions and their unique contributions to chemistry, including the effective collection of reaction products, unique growth models of precipitates, and a simple strategy for the alignment/assembly of nanoscale building blocks. Finally, a short perspective is provided on the potential for future developments in the field.

“…Micropillars have been reported to be effective wetting defects to control the rupture of solution, form regular liquid bridges, and yield aligned bio‐macromolecular,[19a] polymeric,[19b],[20a,c,d], small molecular,[20b] or inorganic[19c],[20c] nanowire arrays. However, the 1D architectures generated in this way are suspended in air owing to air pockets trapped in superhydrophobic surfaces.…”

Alignment of 1D assemblies of a wide variety of nanoparticles (e.g., metal, metal oxide, semiconductor quantum dots, or organic microspheres) in one direction upon diverse substrates (including industrial silicon wafers and transparent glass plates) by a general strategy is demonstrated. This sandwich method provides an efficient way of rapidly and precisely assembling nanoparticles on a large scale (up to 10 cm × 10 cm) for device applications.

“…Tilting angle of the substrate during the evaporation also plays a fatal role in the shapes of as‐prepared microwires, which displays different liquid films rupture processes on the regular rhombus‐shaped micropillar arrays . Discontinuous liquid bridges were firstly generated among the micropillars on polymeric solvent dripped substrates, and then increased rupture holes converged to form continuous microwire patterns.…”

With facile manufacturability and modifiability, impressive nanoparticles (NPs) assembly applications were performed for functional patterned devices, which have attracted booming research attention due to their increasing applications in high-performance optical/electrical devices for sensing, electronics, displays, and catalysis. By virtue of easy and direct fabrication to desired patterns, high throughput, and low cost, NPs assembly printing is one of the most promising candidates for the manufacturing of functional micro-chips. In this review, an overview of the fabrications and applications of NPs patterned assembly by printing methods, including inkjet printing, lithography, imprinting, and extended printing techniques is presented. The assembly processes and mechanisms on various substrates with distinct wettabilities are deeply discussed and summarized. Via manipulating the droplet three phase contact line (TCL) pinning or slipping, the NPs contracted in ink are controllably assembled following the TCL, and generate novel functional chips and correlative integrate devices. Finally, the perspective of future developments and challenges is presented and widely exhibited.
