Fabrication of slippery Zn surface with improved water-impellent, condensation and anti-icing properties

Long-term deterioration of lubricant-infused nanoporous anodic aluminium oxide surface immersed in NaCl solution

“…The low surface energy of the liquid lubricant enables the surface a slippery feature useful for the reduction of water condensation, microbial fouling and ice nucleation [15,16]. Additionally, the seamless feature of the hydrophobic lubricant layer may also protect the substrate from being attacked by external corrosive media, making LIS/SLIPS an emerging surface technology for wide potential applications in corrosive underwater conditions [17][18][19][20]. Generally, the criteria of designing a LIS are extremely rigorous: i) the lubricant must fully wet the micro-/nanoporous surface of the LIS substrate; ii) the lubricant is immiscible with the fluids it contacts; and iii) the contacting fluids cannot penetrate into the LIS substrate [21][22][23].…”

PDMS-Infused Poly(High Internal Phase Emulsion) Templates for the Construction of Slippery Liquid-Infused Porous Surfaces with Self-cleaning and Self-repairing Properties

“…Recently, Aizenberg et al have reported an alternative method to develop omniphobic surfaces inspired by Nepenthes. , They found that these pitcher plants with special surface microtexture could become very slippery when moistened by condensation or nectar, which could help them trap insects into death. , Based on this interesting phenomenon, they constructed an omniphobic surface by overfilling a lubricant liquid onto a rough surface, which is called a slippery liquid-infused porous surface (SLIPS) . By changing the traditional solid–liquid interface of the porous surface and test liquid to a smooth liquid (lubricant liquid)–liquid (test liquid) interface after overfilling the surface with the lubricant, SLIPS featured a very low sliding angle and low surface friction coefficients .…”

A Superhydrophobic Self‐Cleaning and Anti‐Icing Aluminum Sheet Fabricated by Alkaline Solution

“…[23,24] Many methods have been developed to prepare a superhydrophobic aluminum alloy surface, such as anodic oxidation processing, microarc oxidation, laser cladding, fluorocarbon coating, and thermal spray treatment. [25][26][27][28][29][30] However, the shortcomings of high energy consumption and environmental contamination hinder those methods from large-scale applications.…”

[25][26][27][28][29][30] However, the shortcomings of high energy consumption and environmental contamination hinder those methods from large-scale applications.Besides the traditional methods, superhydrophobic aluminum materials, which are equipped with mechanical durability and anti-icing property, have been considered as appropriate candidates for the plane shell. [31][32][33][34][35] Recently, researchers have fabricated an enormous amount of superhydrophobic materials for mechanical durability improvement though Beck's etchant and demonstrated treatments such as rare-earth-salt-solution boiling bath method, sandblasting and chemical modification, and novel one-step hydrothermal method.…”
