Assessment of the hydration/dehydration behaviour of MgSO4∙7H2O filled cellular foams for sorption storage applications through morphological and thermo-gravimetric analyses

Compared to pure salt, it was evidenced that salt filled composite foams have a significant de/hydration capacity. The water/salt reaction is not hindered by the foaming process. Based on morphological and thermo-physical properties of the foam a simplified vapour diffusion flow process in composite foams was proposed.
