A Photoelectric Synergistic Flexible Solid Slippery Surface for All-Day Anti-Icing/Frosting

Area of Science:

• Materials Science
• Surface Engineering
• Nanotechnology

Background:

• Ice accumulation on surfaces poses significant risks in transportation and aerospace.
• Traditional rigid anti-icing materials are inadequate for irregularly shaped objects and curved surfaces.
• There is a critical need for flexible anti-icing solutions adaptable to diverse geometries.

Purpose of the Study:

• To develop a flexible solid slippery surface (FSSS) with photoelectric synergistic properties.
• To evaluate the anti-icing and de-icing capabilities of the FSSS on both flat and curved surfaces.
• To assess the long-term stability and self-healing properties of the FSSS under various environmental conditions.

Main Methods:

• Fabrication of the FSSS using flexible basalt fiberglass cloth, copper foil, polyurethane/carbon nanotubes mixture, and a solid lubricant blend.
• Testing anti-icing and de-icing performance at temperatures as low as -80 °C.
• Evaluating material stability through prolonged exposure to air, water, acidic, and basic environments.
• Assessing self-healing capabilities at -80 °C.

Main Results:

• The FSSS demonstrated excellent all-day anti/de-icing performance on both flat and curved surfaces, even at -80 °C.
• The material exhibited long-term stability when exposed to air (60 days), water (60 days), acid (pH 1, 30 days), and base (pH 13, 30 days).
• The FSSS successfully achieved self-healing functionality at -80 °C.

Conclusions:

• The developed photoelectric synergistic FSSS offers a promising solution for anti-icing and de-icing challenges.
• Its flexibility and durability make it suitable for application on multi-shaped objects in extreme cold environments.
• This flexible surface technology presents a novel approach for future de-icing/frosting applications.
