Organic inorganic phase change materials (PCM) experience a solid/solid phase transition. This transition involves a volume expansion about a few vol % against about 15vol% for solid/liquid PCM. This kind of material would be useful for innovative design geometries to store or manage thermal energy. Such material may be directly integrated into systems through composite solutions or additive manufacturing.
The aim of the study is to synthetize materials previously identified, then perform thermal and structural characterization by SEM, TGA, FTIR, XRD, then provide few tens grams of matter for shaping into composite and/or additive manufacturing processes. Finally, those net shaped materials would be tested and characterized at CEA Grenoble in dedicated thermal facilities and their influence onto thermal warming quantified.
