“…The problem of ice accumulation has always been unavoidable in life and industry, especially for equipment that is exposed to the natural environment year-round, such as highvoltage power lines, railroad tracks, airplanes and ships, and communication facilities [24,[92][93][94][95][96]. Ice accumulation can cause damage to equipment, interfere with its normal operation, and increase maintenance costs.…”

The slippery liquid-infused porous surface(s) (SLIPS) that imitates the Nepenthes pitcher plant has proven to be highly versatile and can be combined with various surface characteristics such as dynamic response, antifouling, selective adhesion, and optical/mechanical tunability. In addition, the introduction of a lubricating fluid layer also gives it extremely low contact angle hysteresis and self-repairing properties, which further expands its application range. Currently, SLIPS has been proven to be suitable for many frontier fields such as aerospace, communications, biomedicine, and microfluidic manipulation. In this review, we explain the theoretical background of SLIPS and the preparation methods currently available, including the choice of substrate materials and lubricants, and we discuss the design parameters of the liquid injection surface and how to deal with the consumption of lubricants in practical applications. In addition, the paper focuses on current and potential applications, such as preventing pathogen contamination of and blood adhesion of medical equipment, manipulation of tiny droplets, and directional transportation of liquids. Finally, some weaknesses that appear when SLIPS is used in these applications are pointed out, which provides a new perspective for the development of SLIPS in the future.

“…Developments of hydrophobic coatings as icephobic coatings are still ongoing [142][143][144][145][146][147][148][149]. Recently, the low ice adhesion of 9 kPa was reported on a micro-nanostructured surface in [150]. Since the 2010s, the slippery lubricantinfused porous surface (SLIPS) has gained attention as an icephobic coating [151,152].…”

Icing on an aircraft is the cause of numerous adverse effects on aerodynamic performance. Although the issue was recognized in the 1920s, the icing problem is still an area of ongoing research due to the complexity of the icing phenomena. This review article aims to summarize current research on aircraft icing in two fundamental topics: icing physics and icing mitigation techniques. The icing physics focuses on fixed wings, rotors, and engines severely impacted by icing. The study of engine icing has recently become focused on ice-crystal icing. Icing mitigation techniques reviewed are based on active, passive, and hybrid methods. The active mitigation techniques include those based on thermal and mechanical methods, which are currently in use on aircraft. The passive mitigation techniques discussed are based on current ongoing studies in chemical coatings. The hybrid mitigation technique is reviewed as a combination of the thermal method (active) and chemical coating (passive) to lower energy consumption.

“…Besides metallic substrates, the anti-icing properties of polymeric materials treated by DLW are attracting a great deal of attention [ 113 ]. In particular, polytetrafluoroethylene (PTFE) is a low-surface-energy polymer with outstanding physical and chemical properties, e.g., resistance to alkali and acid, almost total insolubility in all solvents, low friction coefficient, resistance at high temperature, low dielectric constant, and excellent charge storage stability.…”

In numerous fields such as aerospace, the environment, and energy supply, ice generation and accretion represent a severe issue. For this reason, numerous methods have been developed for ice formation to be delayed and/or to inhibit ice adhesion to the substrates. Among them, laser micro/nanostructuring of surfaces aiming to obtain superhydrophobic behavior has been taken as a starting point for engineering substrates with anti-icing properties. In this review article, the key concept of surface wettability and its relationship with anti-icing is discussed. Furthermore, a comprehensive overview of the laser strategies to obtain superhydrophobic surfaces with anti-icing behavior is provided, from direct laser writing (DLW) to laser-induced periodic surface structuring (LIPSS), and direct laser interference patterning (DLIP). Micro-/nano-texturing of several materials is reviewed, from aluminum alloys to polymeric substrates.
