“…This hydrophobicity boosting phenomenon could be explained also by elastocapillary coalescence [24]. High hydrophobicity of prepared nanorod metal array surfaces enhanced by elastocapillary coalescence creates unacceptable environment for cell adhesion and spreading as it is mentioned in our former publication [18]. Hydrophobic silver nanorod array surfaces are supposed to be used as antiadhesive substrates for bacterial cell adhesion for bacterial cell adhesion to prevent bacterial infection spreading.…”

“…The results for D S γ , polarizability, adhesion force and contact angle were compared to published values for randomly nanopatterned and highly ordered and oriented Ni and Ag surfaces [17] [18] and showed that the surface hydrophobicity increased from random patterned to highly ordered and oriented surfaces (Table 4).…”

Highly ordered nickel and silver nanorods arrays prepared by alumina template assisted electrodeposition were investigated to determine the effect of the array geometry on metal surface hydrophobicity and adhesion forces. The nanorod geometry, clustering and pinning were used to characterize surface hydrophobicity and its modulation. A contribution of metal crystallographic orientation to the surface energy was calculated. To characterize nanorod array surface properties and elucidate the source of the particle adhesion effects has been calculated. The dispersive components of surface tension D S γ and surface polarizability k S , as surface features that markedly characterize hydrophobicity and adhesion, were calculated. The highest hydrophobicity was found for Ag nanorods with aspect ratio of 10 then Ni nanorods with aspect ratio 10. The same geometry of nanorods particles resulted in different surface hydrophobicity and it was ascribed to the orientation of Ag and Ni crystals formed on the top of nanorods. Due to high hydrophobicity nanorod array surfaces could be used as an antifouling surface in medicine to select areas on implant surface not to be colonized by cells and tissues.

“…The method is very economical and does not require expensive equipment. 6 If PDMS was used as the coating, the nanohybrid surface blocked the adhesion and proliferation of living cells. Similar smart polymer surfaces were also prepared by more expensive methods using laser electron beam lithography.…”

“…Electrochemical methods have been used to prepare a Ni based nanostructured surface coupled with a polydimethylsiloxane (PDMS) monolayer using spin -coating. 6 The surface hydrophobicity increased by about 30% in comparison to the Ni surface only and could be modified to enhance the adhesion of ordered biomolecules or the self-assembly of monolayers. Alternative simple methods included the fabrication of a shark-skin-like patterned PDMS modified with carbon nanotubes to form a polymeric superhydrophobic film.…”

IntroductionThe aim of this mini review was zoom in the perspective and feasible methods to produce nanopatterned polymers surfaces and to collect their some properties. This has opened new possibilities for making affordable polymer products with functional nanopatterned surfaces.While a variety of approaches to create hydrophobic/ superhydrophobic surfaces have been developed, [1][2][3][4][5] there are still restrictions on their widespread use due to the cost, number of processing steps, limits on the manufacturable area, durability, instrumentation required, etc. This has led to the development of inexpensive and reliable techniques for the commercial production of hydrophobic layers. Electrochemical methods have been used to prepare a Ni based nanostructured surface coupled with a polydimethylsiloxane (PDMS) monolayer using spin -coating. 6 The surface hydrophobicity increased by about 30% in comparison to the Ni surface only and could be modified to enhance the adhesion of ordered biomolecules or the self-assembly of monolayers. Alternative simple methods included the fabrication of a shark-skin-like patterned PDMS modified with carbon nanotubes to form a polymeric superhydrophobic film.7 A high viscosity paste (comprised of 10 wt % multi walled carbon nanotubes dispersed into PDMS) was placed between two rollers, and the paste was transferred as a smooth film (with less than 300nm roughness) onto the roll with the high rotational speed.7 A spin-coating method has been used to form a biomimetic interface from melanin whose electric signal transduction can be modified.8 High density plasma processing was employed to create a nanotextured superhydrophobic transparent poly (methyl methacrylate) surface. 9 By appropriate tuning of the plasma conditions, either random or ordered hierarchical structures of high aspect ratio and surface area could be reproducibly created. Such plasma treated polymeric surfaces have been evaluated as substrates for efficiently controlling the wettability, biomolecules immobilization, and cell adhesion of the surface, paving the way to a wide spectrum of applications. A three-dimensional plasma micro-nanotextured cyclo-olefin-polymer surfaces has been used for biomolecules immobilization because of its environmentally stable superhydrophobic and superoleophobic properties.10 Plasmas could also be used to deposit fluorocarbons on a cyclo-olefin polymer to enhance hydrophobicity 11 with good adhesion and effective surface protection reducing plastic deformation. A micro reactive ion-etching method has been used to prepare nanotextured films from PDMS for enhanced cancer cell isolation. 12Slippery liquid-infused porous surfaces show great promise for preventing biofilm formation owing to their low surface energy in combination with their self-cleaning properties. 13 Li and co-workers demonstrated a novel hydrophobic liquid-infused porous poly (butyl methacrylate-co-ethylene dimethacrylate) surface with bacteriaresistance in BM2 mineral, which had medium and long-term stability in aque...

“…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.
