The foam stabilization requires substances that are amphiphilic in nature. Plant cell wall components (PCWC) are mostly hydrophilic. PHYTOFOAM will attempt to functionalize, i.e. to partially hydrophobize these PCWC extracted from biomass to produce foam. Such wet foam’s stability will be correlated to physico-chemical properties of functionalized PCWCs. Drying process is detrimental to foam stability. The drying process induces pressure differences within the bubbles due to gradient of water distribution in foam height. Inspired from plant tissue’s ability to conduct water against gravity, capillary structures will be incorporated into the wet foam to reduce the water concentration gradient and monitor its drying process. Under controlled temperature and relative humidity while utilising interferometric methods, the changes that wet foam undergoes while drying will be tracked. Finally, the mechanical properties of dried (solid) foams will be studied.
