Oily Long-Term Anti-Icing Coating Based on Hydrophobic Cross-Linking Composite Resin.

Area of Science:

• Materials Science
• Surface Chemistry
• Tribology

Background:

• Developing passive anti-icing surfaces is crucial for preventing ice formation in various applications.
• Existing anti-icing coatings often face challenges with durability and long-term effectiveness.

Purpose of the Study:

• To propose and investigate a new type of passive anti-icing coating: interfacial lubrication coating.
• To evaluate the anti-icing performance, mechanical properties, and durability of these novel coatings.

Main Methods:

• Preparation of interfacial lubrication coatings using spin-coating or drop-coating methods.
• Incorporation of hydrophobic and lipophilic modified particles to retain oil within a hybrid resin.
• Systematic characterization of surface morphology, wettability, ice adhesion, and mechanical durability.

Main Results:

• The hybrid resin-based coating using fluorinated ethylene-vinyl ester copolymer (FEVE) and polyurethane (PU) demonstrated superior anti-icing performance.
• Achieved ice adhesion as low as 11 kPa and an icing delay time of 779 s.
• Exhibited excellent long-term stability, with minimal increase in ice shear strength after 6 months.

Conclusions:

• The interfacial lubrication coating design, utilizing modified nanoporous SiO2 and specific structural properties, effectively retards oil release and maintains lubricity.
• This approach offers a promising strategy for developing efficient and durable anti-icing coatings.
• The study provides valuable insights for future anti-icing material design.
