In the present work a macroporous silicone foam, able to contain the magnesium
sulfate, was chosen as matrix for the reversible hydration/dehydration process of
the salt hydrate. The aim of the article was addressed towards the assessment of the
relationship among microstructure, permeability and mass diffusion of the composite foam. This aspect represents an essential step for the future industrial development of this composite material. The results show that the filler content influences
the foam morphology where a transition from closed to mixed and then closed cell
again was observed with increasing filler content. Consequently, depending on the
distribution and interconnection of the structural channels, a different effectiveness
in guaranteeing mass diffusion phenomena was identified. In particular, permeability tests show that foams with 50 wt% of salt hydrates have a highly interconnected
microstructure allowing a permeability over three times higher than a closed cell
structure making it suitable for thermochemical energy storage applications. [-]
