Self-cleaning white roof surfaces by laser nanotexturing
FLITE Material Sciences offers a laser nanotexturing solution that imparts superhydrophobic properties to white roof surfaces, enhancing their self-cleaning capabilities without coatings. The technology replicates lotus-leaf surface features, improving material durability and reducing maintenance.
Overview
FLITE Material Sciences introduces an innovative solution for enhancing the durability and cleanliness of white roof surfaces through laser nanotexturing. This technology mimics the superhydrophobic properties of lotus leaves, enabling surfaces to repel water and reduce the adhesion of contaminants such as dust, soot, and ash. Unlike conventional methods that rely on chemical coatings, this process directly modifies the surface texture, maintaining the substrate's strength and resistance to environmental stressors.
Technical specifications
Key features:
- Laser nanotexturing directly reproduces lotus-leaf surface features on various substrates.
- Superhydrophobic properties ensure effective water repellency and reduced dirt adhesion.
- No chemical coatings needed, preserving the material's intrinsic properties.
The process is designed to withstand various environmental conditions, including thermal cycling, strong air currents, and exposure to conventional contaminants. Validation tests will assess water repellency, color fastness, and material durability in compliance with ASTM standards.
Technology readiness level
This technology is currently at TRL 5, indicating that it has been validated in a relevant environment. Future testing will involve further validation through exposure to real-world conditions over extended periods to ensure the long-term effectiveness of the superhydrophobic properties.
About FLITE Material Sciences
FLITE Material Sciences is a surface engineering company that utilizes laser surface functionalization to modify materials, offering an alternative to traditional, often toxic, chemical coatings. By retexturing the surface of materials such as metal, plastic, glass, and semiconductors at a microscopic level, the company enables these surfaces to autonomously repel substances like water, oil, ice, and bacteria. This process enhances material durability and performance without weakening the underlying substrate, providing a cleaner, more sustainable solution for industrial manufacturing. The technology is applicable across a wide range of sectors, including aerospace, defense, automotive, oil and gas, and life sciences.
For industrial partners and customers, FLITE’s solutions address critical maintenance and durability challenges by extending the operational life of equipment and reducing long-term upkeep costs.
