Meet Guang Chu from Aalto University, one of the brilliant minds within the Finnceres Ecosystem. Chu is exploring how photonics and cellulose can be used for creating colors without pigments.
Chu was granted the highly revered Novo Nordisk Grant for a 3-year research project focusing on photonic materials and cellulose colloidal liquid crystals.
Cellulose-based photonic materials change appearance based on the architecture of the cellulose structure, which affects how light interacts with it. This allows cellulose to be modified to exhibit different colors without using pigments, such as green, blue or even transparent.
This research paves the way for a more sustainable approach to paints, coatings, and pigments.
