Area of Science:

• Materials Science
• Surface Chemistry
• Biomimetics

Background:

• Icing poses significant risks to various applications, including aircraft and infrastructure.
• Current anti-icing methods have limitations like short frost delay, poor durability, and production challenges.

Purpose of the Study:

• To develop a durable and scalable anti-icing solution inspired by natural biological systems.
• To create a dynamic interface with exceptional anti-icing, anti-adhesion, and de-icing properties.

Main Methods:

• Developed organohydrogel dynamic interfaces mimicking mollusk mucus secretion.
• Investigated the dynamic and reversible exchange of cryoprotectant and water at the interface.
• Evaluated superlubricity, frost delay time, and ice adhesion under subzero conditions.

Main Results:

• Achieved superlubrication with a sliding angle of 1.9 ± 0.4 degrees.
• Demonstrated a frost delay time of up to 970 ± 31 minutes under high humidity.
• Exhibited long-term durability and replenishable properties.

Conclusions:

• Organohydrogel dynamic interfaces provide a reliable and scalable solution for preventing icing and ice adhesion.
• The developed coating is effective even in extreme cold environments for critical infrastructure and transportation.
• This biomimetic approach offers a promising strategy for advanced anti-icing technologies.
