“…Since then, low surface energy materials and fabrication techniques have been explored to design and create superhydrophobic surfaces [18,19]. Nanostructured superhydrophobic surfaces have been fabricated using silica based materials and tridecafluoro-1,1,2,2-tetrahydrooctyldimethylchlorosilane (TFCS, CF 3 (CF 2 ) 5 (CH 2 ) 2 (CH 3 ) 2 SiCl) through dip coating technique [20]. Shang et al [21] have fabricated superhydrophobic silica film on glass substrates using polystyrene particles and DFMS (dodecafluoroheptyl-methyl-dimethoxysilane) as low surface energy material.…”

Abstract.A facile process for in-situ modification of surface properties of Waste Expanded Polystyrene (WEP)/graphite film produced by spin coating technique has been described. The additives undergo spontaneous surface agglomeration with formation of islands of forest of flake structure during the spinning process. This results in polymer films with enhanced roughness and highly hydrophobic surfaces. Wettability was analyzed using static water contact angle, surface morphology was observed using atomic force microscopy (AFM) and field emission scanning electron microscopy (FE-SEM). The polymer composite exhibited maximum water contact angle (WCA) of 129°. Surface texture reveals the variation of surface roughness which enables anisotropic surface wettability property. The present work exhibits promising approach for fabricating nano flake forest in polymer structures for various industrial applications.

“…International Journal of Corrosion The hydrophobicity is usually improved by increasing the surface roughness [205,206] and the hydrophobic substrate requires an adequate surface roughness [207]. Therefore, techniques for making hydrophobic coatings are divided into two steps: (i) creating of a rough surface at microscale for host materials and (ii) creating nanoscale architecture surface (see Figure 9), followed by the deposition of low surface energy materials on the surface.…”

“…It should be noted that when the roughness increases, the angle of contact with water will increase or decrease depending on the surface being hydrophobic or hydrophobic [205]. Furthermore, Zhu et al [208] argued that both the nanostructure and microstructure of the surface contribute to its hydrophobicity, as observed in the nature (the lotus leaf).…”

Incorporation of nanofillers into the organic coatings might enhance their barrier performance, by decreasing the porosity and zigzagging the diffusion path for deleterious species. Thus, the coatings containing nanofillers are expected to have significant barrier properties for corrosion protection and reduce the trend for the coating to blister or delaminate. On the other hand, high hardness could be obtained for metallic coatings by producing the hard nanocrystalline phases within a metallic matrix. This article presents a review on recent development of nanocomposite coatings, providing an overview of nanocomposite coatings in various aspects dealing with the classification, preparative method, the nanocomposite coating properties, and characterization methods. It covers potential applications in areas such as the anticorrosion, antiwear, superhydrophobic area, self-cleaning, antifouling/antibacterial area, and electronics. Finally, conclusion and future trends will be also reported.

“…Surface micro-and nanopatterning is widely used to create hierarchical structures needed to induce surface hydrophobicity and superhydrophobicity. Traditional approaches generally rely on structuring an already hydrophobic surface or on hydrophobizing a rough hierarchically-structured surface, employing a broad range of techniques and materials [1, [7][8][9][10][11][12][13][14][15][16]. Micro-and nanopatterning can also be achieved with lasers, however their use as a procedure to induce direct hydrophobicity and superhydrophobicity in metallic surfaces is only emerging.…”

Abstractauthoren Nickel thin films were deposited on Ti6Al4V and surface treated with nanosecond pulse ultraviolet laser in ambient conditions using a fluence of 3.68 J cm−2. A twofold to threefold increase in contact angle was observed for water, ethylene glycol, and diiodomethane following laser treatment, with recorded contact angles for water in excess of 130°. No additional treatment was used to hydrophobize the surface. Three different micro‐ and nanometric levels of roughness were generated on the thin film surface, which can be related to the rastering parameters of the laser and to the increase in apparent contact angle. Melt droplets were identified as a main contribution to the nanometric roughness level, indicating that melting and melt ejection play an important role in surface nanostructuring. Micro‐ and nanopatterning obtained after UV laser treatment of nickel thin films, highlighting the different scales of the generated features.
