Title
(EN) PHASE-CHANGE MATERIAL FOR STORING THERMAL ENERGY, MANUFACTURING METHOD AND USES OF SUCH A MATERIAL
(FR) MATERIAU A CHANGEMENT DE PHASE POUR LE STOCKAGE D'ENERGIE THERMIQUE, PROCEDE DE FABRICATION ET APPLICATIONS D'UN TEL MATERIAU
Abstract
(EN)
The invention relates to a method for synthesising a solid-solid organic phase-change material, made of polyurethane, the method comprising: a step (i) of mixing and reacting a liquid polyethylene glycol, a cross-linking agent and a liquid polyisocyanate, by mechanical agitation, at a first controlled temperature, in an enclosure, in order to obtain the liquid polyurethane; and a step (ii) of curing the liquid polyurethane, at a second controlled temperature, in order to make the polyurethane solid, the mixing of step (i) being carried out in the absence of solvent.
