“…The deposition of the droplets in many fields is unexpected, such as self-cleaning anti-icing, ,, and antifogging, , and great effort has been made to remove the droplet by homogeneous coalescence-induced jumping behaviors. In the above studies, however, it is seen that this strategy fails to remove the “D-droplet”, as proven by Figure S2.…”

The removal of the deposited droplets on a solid surface is crucial to considerable practical applications that require self-cleaning properties. In this work, a strategy of cleaning a deposited droplet ("D-droplet") by coalescing with a heterogeneous and easily jumping droplet ("J-droplet") is proposed. Molecular dynamics simulation studies have shown that the coalescence of these two kinds of droplets would not guarantee the removal of D-droplet, unless the lifting ability of J-droplet is enhanced through the reduction of the solid−liquid interaction. However, this is a bad scenario with low efficiency. Further investigation suggests that by introducing two J-droplets to produce triple-coalescence dynamics, the D-droplet could be successfully jumping from the substrates due to the coalescence-induced effect, which is also verified by the free energy calculation. Moreover, the effects of the size of the droplets and the arrangement mode of these three droplets on the jumping dynamics are both considered. The studies not only help advance our understanding of coalescence-induced jumping of heterogeneous droplets, but also open up new ways to remove the deposited impure droplets, which is expected to guide the fields of self-cleaning.

“…Over the past decade, PB surfaces have received much attention due to their potential applications in lubrication, antifogging, antifouling, self-cleaning, antiadhesion, and antibacterial effects (Figure ). − PB surfaces are prepared by two main strategies, namely, “grafting to” and “grafting from” . In the former strategy, the PB surface is constructed through the formation of chemical bonds between the active groups on the surface and the active end groups of the polymer long chain.…”

Research on polymer brushes (PBs) has aroused great interest due to their wide range of applications in lubrication, antifogging, antifouling, self-cleaning, antiadhesion, antibacterial effects, and so forth. However, the weak mechanical strength, especially the low bond strength between the PBs and the substrate surface, is a long-standing challenge for its practical applications, which is directly related to the service life of the PB surface. Fortunately, the imperfection of the PB surface was gradually solved by researchers by combining the action of the chemical and physical anchoring strength, and many shear-stable PB surfaces were developed. In this Perspective, we present recent developments in the studies of shear-stable PBs. Conventional strategies that altered the structure of PB chain methods, including increasing grafted density, cross-linking of PBs, cyclic PBs, and so forth, are introduced briefly. The systematic subsurface grafting of the polymer brush (SSPB) strategy was introduced emphatically. The SSPB method grafted PB into the subsurface with considerable depth and gave a robust and reusable PB layer, which provided an approach for tackling the shear-resistance issue. Besides, the robust hydrophobic poly(dimethylsiloxane) (PDMS) brush surface that lubricated itself in air was also introduced. Finally, we provide a synopsis and discuss the outlook of the shear-stable PB surface.

“…Since the resulting fog reduces the transmittance of light, anti‐fog coatings are necessary to prevent accidents from refraction and reflection of light and to increase living comfort.

“…With the wide usage area of anti-fog coatings, this issue attracts the attention of researchers around the world and continues to be studied in the literature. [1][2][3][4][5][6] Among the anti-fog film coatings that prevent the condensation of water in small droplets, polymeric materials stand out for their biocompatibility and their excellent adhesion to various surfaces without precoating. For example, the anti-fog surface obtained by coating acrylic resin polymer on the polycarbonate substrate surface exhibited high adhesion properties, 7 superhydrophobic and biocompatible coatings were obtained on glass, polypropylene, and aluminum substrates by using SEBS polymer.…”

Anti-fog surfaces have an important place in many areas of daily life. In this study, hybrid coatings of anti-fog chitosan (CHI) and polyethyleneimine (PI) were realized as an innovative film layer. CHI/PI hybrid coatings, produced by the drop-casting method, which is a practical and one-stage deposition process, were coated on the glass and safety glasses substrates. It has been analyzed that the optimum CHI/PI coating is 2:3 (v/v) mixing ratio, which has a contact angle of 4.9 , a hydrodynamic radius of 5.67 nm, and zeta potential of 38.8 mV. It was analyzed that the coating was successfully performed on the surface by FTIR analysis. It was observed that the coating surfaces were obtained as homogeneous and smooth with FESEM and surface profilometer analyzes. Both steam and cold fog tests were carried out to determine the antifogging properties of different surfaces after coating. After the anti-fog tests, the CHI/PI coating had high-transmittance values in the range of 85.9% and 84.6%. After the coatings were exposed to hot-cold environment cycles and subjected to long-term stability testing, the coatings retained their anti-fog properties.
