A superhydrophobic fabric coating with hierarchical structure was fabricated by a dip coating, in which dodecyltrimethoxysilane (DTMS)‐modified alumina (Al2O3) was used as modifier and polydimethylsiloxane (PDMS) as additive. The effects of the amounts of Al2O3 nano‐sized particles and PDMS on the water contact angle (WCA) and the sliding angle (SA) of the as‐prepared fabrics coating samples were studied. The surface morphology of the as‐prepared samples was characterized by SEM, and the abrasion resistance and chemical resistance experiments were performed by abrasion resistance test, tape tear test, and chemical soaking test. The results show that WCA and SA of the superhydrophobic fabrics coating are 158° and 6°, respectively. With the increasing addition of PDMS, the abrasion resistance of hydrophobic fabrics coating is improved. The WCA value of the as‐prepared fabrics coating is still >150° after five abrasion cycles. The obtained fabrics exhibit excellent superhydrophobicity and oleophilicity due to the hydrophobic modification of DTMS for Al2O3 nano‐sized particles. And the separation efficiency of the as‐prepared superhydrophobic fabrics coating for n‐dodecane and water system can reach 99.98%. POLYM. COMPOS., 2018. © 2018 Society of Plastics Engineers

“…PVD processes are often conducted in a vacuum, plasma or electrolytic environment, which can minimize gas contamination during the deposition process. In accordance with the deposition steps, Li et al [123] employed a plasma spray system to deposit Samaria-doped ceria (SDC) at a low pressure on a ceramic substrate. And the surface was secondarily modified by stearic acid or 1,1,2,2tetrahydroperfluorodecyltrimethoxysilane (FAS) (Figure 8A).…”

Multiscale nano/micro-structured surfaces with superhydrophobicity are abundantly observed in nature such as lotus leaves, rose petals and butterfly wings, where microstructures typically reinforce mechanical stability, while nanostructures predominantly govern wettability. To emulate such hierarchical structures in nature, various methods have been widely applied in the past few decades to the manufacture of multiscale structures which can be applied to functionalities ranging from anti-icing and water–oil separation to self-cleaning. In this review, we highlight recent advances in nano/micro-structured superhydrophobic surfaces, with particular focus on non-metallic materials as they are widely used in daily life due to their lightweight, abrasion resistance and ease of processing properties. This review is organized into three sections. First, fabrication methods of multiscale hierarchical structures are introduced with their strengths and weaknesses. Second, four main application areas of anti-icing, water–oil separation, anti-fog and self-cleaning are overviewed by assessing how and why multiscale structures need to be incorporated to carry out their performances. Finally, future directions and challenges for nano/micro-structured surfaces are presented.

“…The study was focused on the influence of such an important coating parameter as the nanolayer period λ on a cluster and hierarchical structure using an example of the Ti-TiN-(Ti,Cr,Al)N coating with a nanostructured wear-resistant layer (Figure 8). For a coating with λ = 10 nm (Figure 8a), there is a formation of hierarchical feather-like structures, modeled and described, in particular, in [19,20,[24][25][26] for various techniques of the coating deposition. While a coating is being deposited, there in an obvious increase in the cluster size.…”

“…Thus, the most accurate and complete simulation of the deposition process should take into account the stochastic nature of this process and consider the molecular level, because a coating is formed precisely at this level. Several studies [24][25][26] consider a cluster, hierarchical structure of the coating, deposited through various methods, and the influence of the deposition process parameters on the formation of such structure. However, the influence of the parameters of the nanolayer coating structure on the formation of hierarchical structures in the coating requires an additional study.…”

The study proposes a model for the deposition of coatings, which takes into account the stochastic nature of the deposition process and is built considering the influence of the parallel convection and diffusion processes. The investigation has found that the dispersion of the motion direction of deposited particles in front of a substrate increases, which indicates a growth of the randomness in the trajectories of the particles being deposited. The obtained formulas indicate the fractal nature of the deposition process. During the formation of the multilayer coating structure, mismatched fractal structures of the layers overlap each other and thus the clustering effect is largely leveled out. The value of the nanolayer λ period has a significant influence on the fractal structure of the coating and the formation of feather-like hierarchical structures in it.
