Structured porous whitening layer without tio2
A novel structural whitening approach using controlled porous microstructures to increase light scattering without TiO2. This method enhances whiteness through engineered pore size and surface roughness, offering a sustainable alternative for various applications.
Overview
This innovative solution presents a structural whitening approach that eliminates the need for traditional TiO2 pigments. By leveraging controlled porous microstructures, this method increases visible light scattering through the air/polymer refractive-index contrast, along with optional low-loading non-TiO2 mineral or bio-based scatterers. This approach maintains softness, flexibility, and absorbency, making it suitable for various applications, including thin coatings, porous layers, fiber surface treatments, or whitening interlayers.
Technical specifications
Key features:
- Utilizes engineered pore size and fiber/film geometry for enhanced light scattering.
- Incorporates surface roughness and multilayer optical scattering for increased whiteness.
- Compatible with low-loading alternative scatterers to reduce TiO2 reliance.
- Preserves tactile feel, liquid handling, and flexibility, adaptable for diverse applications.
Applications:
- Can be applied as a thin coating or interlayer for textiles, papers, or packaging.
- Suitable for food-grade applications, aligning with vegan, kosher, and halal standards.
Technology readiness level
Currently at Technology Readiness Level 2, this solution is in the early stages of concept validation. Initial phases focus on defining application targets, regulatory constraints, and optical benchmarks. Future phases aim to refine the architecture for practical use while ensuring compliance with food-grade and clean-label standards.
