The present paper deals with the preliminary study carried out on innovative polymeric foams based on silicone and MgSO4∙7H2O. Composites with variable quantity of embedded salt, from 40 wt.% up to 70 wt.%, were prepared, according to an established foaming procedure. A preliminarily physico-mechanical characterization was carried out to investigate the main properties of the composite foams. Thermo-gravimetric dehydration tests, under real operating conditions, demonstrated that the tested samples are able to efficiently exchange water. Static compression tests evidenced high compression stability indicating high flexibility of the cellular silicone structure. Furthermore, the morphological characterization showed that the foam pores were homogenously distributed and well interconnected to each other. The high silicone matrix flexibility and interconnected cellular structure of the composite foam were identified as potentially key factor in order to guarantee good durability and water vapour kinetic diffusion of these composite structures for heat storage applications

Abstract
The present paper deals with the preliminary study carried out on innovative polymeric foams based on silicone and MgSO4∙7H2O. Composites with variable quantity of embedded salt, from 40 wt.% up to 70 wt.%, were prepared, according to an established foaming procedure. A preliminarily physico-mechanical characterization was carried out to investigate the main properties of the composite foams. Thermo-gravimetric dehydration tests, under real operating conditions, demonstrated that the tested samples are able to efficiently exchange water. Static compression tests evidenced high compression stability indicating high flexibility of the cellular silicone structure. Furthermore, the morphological characterization showed that the foam pores were homogenously distributed and well interconnected to each other. The high silicone matrix flexibility and interconnected cellular structure of the composite foam were identified as potentially key factor in order to guarantee good durability and water vapour kinetic diffusion of these composite structures for heat storage applicationsPubblicazioni consigliate
