Cellulosed based foams for water purification

We have designed foams which are built only from green components and can be prepared in up-scalable and easy manner: blending and oven-drying. Amyloid nanofibrils are used mainly as a foaming agent and cellulose nanofibrils are playing the role of the main visco-elastic stabilizer. We also use covalent cross-linking to enhance foam resistance towards capillary collapse during drying. Due to presence of different functional groups such foams have a perspective to be used as water and air purifiers.
