Method for Processing a Superhydrophobic Surface and Solid Substrate Having a Superhydrophobic Surface Structure Produced Thereby

Dual-Scale Superhydrophobic Surface Processing Technology

This technology relates to a surface-processing technique that creates a superhydrophobic surface by forming both microstructures and nanostructures on a metal substrate surface.

Conventional methods for forming hydrophobic surfaces have often relied on costly semiconductor-level micromachining or complex surface treatments. This technology combines particle blasting, anodization, and replication to form a dual-scale surface structure in which micro-scale roughness and nano-scale pores coexist.

As a result, it can secure high hydrophobicity and non-wetting characteristics while improving large-area applicability and mass producibility, making it advantageous for anti-condensation, anti-fouling, and self-cleaning functional surfaces.

Key Features:

• It forms micro-scale roughness on a metal substrate surface through particle blasting.
• It forms nano-scale pores through anodization treatment.
• It realizes a dual-scale superhydrophobic surface structure through a replication process.
• It is suitable for self-cleaning, anti-fouling, and anti-condensation functional surface applications.
