Durability of Slippery Liquid-Infused Surfaces: Challenges and Advances

Slippery liquid-infused porous surfaces (SLIPS) have emerged as a unique approach to creating that can resist fouling when placed in contact with aqueous media, organic fluids, or biological organisms. These are composed of essentially two components: liquid lubricant is locked within the protrusions textured solid due capillarity. Drops, immiscible lubricant, exhibit high mobility and very-low-contact-angle hysteresis on such surfaces. Moreover, these shown adhesion wide range withstand pressure, able self-clean. Due remarkable properties, SLIPS considered promising candidate for applications designing anti-fouling anti-corrosion surfaces, drag reduction, fluid manipulation. collective however, only available long remains infused surface protrusions. A number mechanisms drive depletion from interior texture, leading loss functionality SLIPS. Lubricant one challenge hindering real-world application This review mainly focuses studies conducted context enhancing retention abilities In addition, concise introduction wetting transitions structured well given. We also discuss, briefly, responsible depletion.
