Area of Science:

• Materials Science
• Surface Engineering
• Nanotechnology

Background:

• Water icing causes significant damage to infrastructure and human safety.
• Superhydrophobic surfaces inspired by the lotus effect offer energy-free anti-icing properties.
• Conventional and macrostructured superhydrophobic surfaces have limitations under extreme conditions and photothermal surfaces rely on solar illumination.

Purpose of the Study:

• To review recent advances in anti-icing using superhydrophobic surfaces.
• To introduce mechanisms and advantages of different superhydrophobic surface types.
• To present macrostructured photothermal storage superhydrophobic (MPSS) surfaces as a novel solution for all-day anti-icing.

Main Methods:

• Review of conventional, macrostructured, and photothermal superhydrophobic surfaces.
• Introduction of macrostructured photothermal storage superhydrophobic (MPSS) surfaces.
• Integration of macrostructured superhydrophobic materials, photothermal materials, and phase change materials (PCMs).

Main Results:

• Conventional and macrostructured superhydrophobic surfaces can lose icephobic properties in extreme conditions.
• Photothermal superhydrophobic surfaces are dependent on solar illumination.
• MPSS surfaces demonstrate potential for all-day anti-icing by combining multiple functionalities.

Conclusions:

• MPSS surfaces represent a promising strategy for overcoming limitations of existing anti-icing technologies.
• MPSS surfaces integrate macrostructured superhydrophobicity, photothermal energy storage, and phase change materials.
• Further research and development are needed to address practical application challenges for MPSS surfaces.
