“…[1][2][3][4][5][6] Self-assembly of block copolymer (BCP) thin films in particular offers an efficient route to produce a variety of 3D nanostructures, taking advantage of its simple sequence of processing steps. [7][8][9][10][11][12][13][14] Compared with diblock copolymers, triblock and multiblock polymers can produce nanostructures with greater structural diversity and additional chemical functionalities, [15][16][17][18][19][20] and there has been an increasing emphasis on understanding their selfassembly and 3D morphologies. [21][22][23][24][25] However, it is challenging to resolve the morphologies of 3D BCPs comprising more than two polymeric components unless there is good contrast between the microdomains, for example a contrast in density, chemical composition, or reactivity.…”

“…To enhance the superwetting behavior of materials, spin‐coating technique is usually combined with other physical methods. [ 89 , 90 ] Similar to the spin‐coating method, spraying method is also aimed at decorating the surfaces with a low surface energy layer to impart surfaces with enhanced wettability, through spraying and subsequently solidifying the solutions on substrates. [ 91 ] During the spray‐coating process, a glue layer is usually sprayed on the substrate before the spray of the nanoparticle suspensions to enhance the adhesion of functional particles.…”

As a fundamental feature of solid surfaces, wettability is playing an increasingly important role in our daily life. Benefitting from the inspiration of biological paradigms and the development in manufacturing technology, numerous wettability materials with elaborately designed surface topology and chemical compositions have been fabricated. Based on these advances, wettability materials have found broad technological implications in various fields ranging from academy, industry, agriculture to biomedical engineering. Among them, the practical applications of wettability materials in biomedical-related fields are receiving remarkable researches during the past decades because of the increasing attention to healthcare. In this review, the research progress of materials with specific wettability is discussed. After briefly introducing the underlying mechanisms, the fabrication strategies of artificial materials with specific wettability are described. The emphasis is put on the application progress of wettability biomaterials in biomedical engineering. The prospects for the future trend of wettability materials are also presented.

“…Cai et al [17] used candle ash as the template, chemically deposited methyltrimethoxysilane and prepared the rough nano spherical structure body on the glass surface, before removing it through high-temperature calcination to obtain transparent superhydrophobic coating. Chen et al [18] proposed an effective theoretical model capable of predicting the coating surface roughness and CAs, and realized the self-assembling block polymer PS-b-PDMS body nanostructure and acquired the transparent superhydrophobic surface through annealing and plasma etching. Xu et al [19] adopted the nickel plate etched by HNO 3 solution as a template, based on the R2R technology, prepared the PDMS coating on the PET base materials and obtained excellent transparency and superhydrophobicity.…”

High stability and transparent superhydrophobic coating on a glass substrate that can effectively repel the wetting dust as a self-cleaning property are beneficial traits for solving the decrease in optical lens clarity in an unmanned underground mining environment. However, the transparent superhydrophobic coating has still not been applied due to the contradiction between visibility, hydrophobicity and durability. Herein, a sandwich-like superhydrophobic coating was designed and prepared on borosilicate glass, which consisted of a micro/nanostructure body of neutral silicone sealant (primer) and hydrophobic silica nanoparticles (interlayer), as well as a protective layer of ultraviolet (UV) gel. The coated glass exhibited excellent superhydrophobicity towards many aqueous solutions, and had highly visible light transparency of 80% at 4 wt.% primer mass content. Furthermore, significant tests including the droplet impact, hot water boiling, stirring in acetic acid aqueous solution and sandpaper abrasion were performed on our superhydrophobic coating, which indicated that the obtained transparent coating had good stability and excellent mechanical durability. The coated glass also showed a more wonderful self-cleaning property compared with that of the original glass. This superhydrophobic coating on glass substrate, fabricated by a facile and cost-effective layer-by-layer construction approach, has great potential for general and practical application in the unmanned mining environment under multiple dust and atomized water conditions.
