Dr Silvia Vignolini and her team in the Department of Chemistry, University of Cambridge and her collaborators at the University of Aalto, have developed a process for producing bright white (highly scattering) films with nano-fibrillated cellulose. This is expected to enable a new generation of pigment-free, biodegradable, white material as a potential replacement for titanium dioxide and zinc oxide.
- The material is biodegradable, ideal for food colouring and cosmetics
- Potential replacement for titanium dioxide, which is being phased out
- Fabricated from a readily available natural material, highly suitable for upscaling
- Completely opaque at tens of microns thick
