“…11,12 Ou et al 13 prepared superhydrophobic textured copper surfaces by CE/oxidation and surface uorination, and found that the lm showed much better corrosion protection as compared with the control samples. Mo et al 14 showed that tribological performance could be induced by designing a suitable surface texture combined with modication with a hydrophobic anion on the surface. Zhao et al 15 prepared Au surfaces with micro/nano-hierarchical structures by replication of micro-patterned silicon surfaces using polydimethylsiloxane (PDMS) and self-assembly of alkanethiol to create hydrophobic micro/nano-hierarchical structures.…”

Aluminum alloy surfaces with micro/nano-structures were fabricated via a simple chemical etching (CE) method.After chemical modification with perfluorodecyltriethoxysilane (PFDS), noctadecyltriethoxysilane (OTS) and aminopropyltriethoxysilane (APS), surfaces with different wettability were obtained. The morphology and chemical elements of the as-prepared surfaces were investigated by atomic force microscopy (AFM), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). In addition, the influence of the surface morphology and chemical modification on the wetting/dewetting properties was investigated. Finally, the anti-corrosion and tribological properties of the as-prepared self-assembled monolayers (SAMs) were characterized using an electrochemical workstation and UMT-3 tribometer. The influence of surface morphology and SAMs on the anticorrosion and tribological performances is discussed in detail. The results showed that the optimal preparation conditions consisted of a 40% volume fraction of hydrochloric acid with a CE time of 2 min. The corrosion resistance of the surfaces chemically modified with hydrophobic groups was much better than that of those modified with hydrophilic groups. Also, the combination of micro/nano-structures and suitable SAMs on aluminum alloy surfaces could greatly enhance the friction reduction and wear resistance behavior.

“…Diverse strategies have been developed for controlling wettability of surfaces on the basis of self-assembled monolayer (SAM) and polymeric films in response to environmental changes, such as temperature, solvent, pH, electric charge and oxidation-reduction. Previous research is mainly focused on the reorganization of the surface or internal structure and the orientation of SAMs 35 36 37 . Hereon, we present a direct ion exchange on surface of graphene/IL composite film by ionic liquid (IL) assembly.…”

Wettability of graphene is adjusted by the formation of various ionic surfaces combining ionic liquid (IL) self-assembly with ion exchange. The functionalized ILs were designed and synthesized with the goal of obtaining adjustable wettability. The wettability of the graphene surface bearing various anions was measured systematically. The effect of solvent systems on ion exchange ratios on the graphene surface has also been investigated. Meanwhile, the mechanical properties of the graphene/IL composite films were investigated on a nanometer scale. The elasticity and adhesion behavior of the thin film was determined with respected to the indentation deformation by colloid probe nanoindentation method. The results indicate that anions played an important role in determining graphene/IL composite film properties. In addition, surface wetting and mechanics can be quantitatively determined according to the counter-anions on the surface. This study might suggest an alternate way for quantity detection of surface ions by surface force.

“…Surface textures and chemical modification are commonly used in magnetic data storage systems and microelectromechanical systems (MEMS) to reduce surface force to lessen the possibility of mechanical failure . A number of fabrication methods were used to generate micro/nano hierarchical structures for surface force control, including laser interface patterning, plasma/chemical etching, soft photolithography, sol–gel processing and solution casting, self‐assembled monolayers, electrical deposition, dip‐pen printing, and atomic force microscopy (AFM) local anodic oxidation, etc. Among the surface modification methods, the formation of self‐assembled monolayers (SAMs) proved to be a simple and economic technique for the adhesion control of solid surfaces.…”

a Adhesion and lateral force were controlled by the formation of a self-assembled monolayer combined with the surface ion exchange of ionic liquids on a silicon surface. In this study, the functionalized imidazolium ionic liquids were designed and synthesized with the aim of controlling surface force. N-[3-(Trimethoxylsilyl)propyl] ethylenediamine molecules were first self-assembled onto a surface as an anchor layer and then 1-propionic acid-3-methylimidazolium chloride were successfully grafted onto the amino-modified surface. The surface force was changed by surface ion exchange in various anionic solutions. The self-assembly and ion exchange processes were detected by means of attenuated total reflectance-Fourier transform infrared spectrometry and further confirmed by X-ray photoelectron spectra. Adhesion and friction behaviors were systematically investigated by atomic force/friction force microscope. The results indicated that anions played a great role in determining surface properties. Furthermore, surface adhesion and friction can be possibly quantitatively determined by the counteranions on the surface.
