Plasmonic-mie nanoparticle coated roof film for CO₂ conversion using sunlight
A nanoparticle roof coating that converts atmospheric CO₂ into methanol using solar energy. This passive system transforms rooftops into carbon-converting assets, adhering non-invasively to various roof types without compromising integrity.
Overview
The Plasmonic-Mie nanoparticle coated roof film is a groundbreaking solution that converts atmospheric CO₂ into methanol using solar energy. This scalable, flexible nanoparticle roof coating adheres non-invasively to EPDM, TPO, and PVC roofs, preserving their waterproof integrity. It transforms rooftops into carbon-converting assets, providing building owners with a passive system that leverages solar energy without the need for wiring or mounting hardware. The end product, methanol, is a safe, storable energy source, adding value to idle rooftop space.
Technical specifications
The system is based on a thin, porous polymer film embedded with engineered Cu-Cu₂O nanoparticles. These nanoparticles utilize plasmonic-Mie resonances for enhanced sunlight absorption and efficient photocatalytic CO₂ conversion into methanol. Key features include:
- Advanced nanoparticle design: Cu-Cu₂O nanoantennas enhance light absorption and charge separation.
- Weather-resistant polymer matrix: Ensures strong surface bonding without roof penetration.
- Porous structure: Improves light trapping and catalytic contact.
- Non-invasive application: Preserves roof waterproofing while adhering securely.
- Scalable and modular: Simple deployment across various roof types.
Technology readiness level
Currently at Technology Readiness Level 6, this technology has undergone lab validation with specific focus on catalyst optimization, polymer matrix formulation, and prototype testing on different roof types. Future plans include refining nanoparticle synthesis, improving polymer film durability, testing methanol output under controlled conditions, and scaling up for field pilots.
