Multiplex Biomimetic SLIPS With Super-Lubricity to Multiphase Matters.

Area of Science:

• Materials Science
• Surface Chemistry
• Biomimetics

Background:

• Slippery liquid-infused porous surfaces (SLIPS) offer excellent liquid repellency and anti-fouling capabilities.
• Instability in structural integrity and oil film limits the practical applications of conventional SLIPS.
• Biological surfaces like fish scales and Nepenthes inspire robust superwetting designs.

Purpose of the Study:

• To design and fabricate a multiplex biomimetic and robust lubricant-infused textured surface (LITMS).
• To investigate the impact of morphological structure and chemical composition on oil stability, wettability, and lubrication.
• To overcome the limitations of traditional SLIPS by enhancing durability and performance.

Main Methods:

• Utilized laser-coating composite processing technology for fabricating LITMS.
• Systematically investigated the influence of surface morphology and chemical composition.
• Employed biomimetic principles inspired by natural superwetting surfaces.

Main Results:

• The fabricated LITMS demonstrated remarkable repellency towards liquids, ice crystals, and solids.
• Achieved exceptional omniphobicity, anti-icing, and anti-friction properties.
• Established a correlation between surface characteristics and performance metrics.

Conclusions:

• The developed LITMS exhibits superior stability and multiphase repellency compared to conventional SLIPS.
• The biomimetic design and fabrication strategy offer a promising approach for advanced surface engineering.
• This work provides new insights into interfacial phenomena, advancing material protection and machinery lubrication applications.
