Laser-functionalized self-cleaning and anti-stain surfaces for sanitation

Overview

AlchLight has developed an innovative laser surface processing technology that transforms regular materials into superhydrophobic surfaces, providing self-cleaning and anti-stain properties. Unlike chemical coatings, this laser technology permanently alters the material's surface, offering a durable and environmentally friendly solution. The technology is particularly effective in sanitation applications, as it prevents stain formation and repels multiple types of stains, including feces, urine, and bacteria, from surfaces such as ceramics and biodegradable materials.

Technical specifications

• Laser-functionalization: Alters the wetting and optical properties of surfaces without relying on chemical coatings.
• Superhydrophobic performance: Treated surfaces repel stains and contaminants effectively, preventing adhesion and accumulation.
• Durability: The treatment is long-lasting and immune to common issues like flaking and delamination associated with coatings.
• Application versatility: Can be applied to a range of materials, including metals, ceramics, and biodegradable materials.
• Processing capability: The technology can process meter-sized surfaces at nanometer resolution on both flat and curved surfaces.

Technology readiness level

The technology is currently at TRL 4, indicating that it has been validated at a laboratory level and is ready for further development and testing in operational environments.
