“…Experimental results obtained by Zhao et al [84], showed that adhesive force and friction force of DLC films with microgrooves reduced effectively with increase of groove area density and incorporation of thin ILs films. The lowered adhesion and friction force were attributed to two factors including the reduced area of contact between DLC films and colloidal tip, and incorporation of thin ILs films to avoid direct contact between DLC films and colloidal tip and to facilitate sliding of colloidal tip on DLC films.…”

“…However in few studies, the liquid droplet partially enters the patterned surface leading to an intermediate wetting model [31,33] and this could be evaluated by measuring the sliding angle [32]. Thus texturing is an effective way to improve the wetting behavior by reducing the surface real area of contact, and further can be enhanced by combining with chemical modification [15,18,34].…”

The behavior of a liquid on a solid surface has shown great interest in a variety of applications related to surfaces and its interfaces. In this paper, the wetting behavior of DI water on micropatterned silicon surfaces fabricated through photolithography and deep reactive ion etching (DRIE) is investigated. Micro pillars of both solid and hollow geometries at a varying pitch and its arrangement in an array has been examined with static contact angle measurement. However, the results concluded that the arrangement of pillars in an array plays an important role as hollow geometries in the case of chain type arrangement provide both hydrophilic and hydrophobic surface properties, while the same hollow geometries in case of zig-zag orientation experiences only hydrophobicity at a varying pitch. Decreased WCA with increased pitch has been observed in the case of a zig-zag arrangement, due to the effect of capillary and gravitation forces. Also the existence of air pockets at sharp corner in the case of hollow square assists in providing maximum contact angle (WCA=144°) as compared to hollow circle and solid geometries; thus a nonsticky behavior would be possible between the droplet and the patterned surface, due to less adhesion force.

“…These research works usually target at a specific application; especially at high temperature. For example, a novel strategy to improve micro/nano‐tribological properties of DLC film by combining micro‐pattern and thin ionic liquids film was proposed by Zhao et al recently . They fabricated DLC‐IL composite films with microgrooves patterned surfaces, which showed that friction forces decrease with the increase of microgroove density and incorporation of thin ILs film further reduces the friction forces (Figure ).…”

“…The patterned DLC films with micro‐groove from low area density to high area density modified with ILs film are defined as GIL1, GIL2, GIL3, and GIL4, respectively. All tests were run against steel ball at load of 1 N and a sliding frequency of 1 Hz for 1 h. Reproduced with permission . Copyright 2013, ELSEVIER.…”

Ionic liquids (ILs) are fascinating materials with unique combination of solid and liquid properties. Due to high thermal stability and promising tribological properties, there have been increasing research interests in applying ILs as boundary lubricants. In this review, the authors will discuss the recent progress on this topic with the emphasis on the relationship between the molecular arrangement of ILs confined to a solid and the tribological properties. First, the fundamentals on boundary lubrication and the state-ofthe-art lubricants will be reviewed briefly. Second, the progress on the molecular structure of ILs confined to a solid surface will be discussed. Afterward, the experimental and computational efforts on the ILs as boundary lubricants will be discussed in details with emphasis on the effect of IL structure, solid substrates, and IL-soild interaction. Finally, the future research directions will be discussed.
