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.

(FR)
Procédé de synthèse d'un matériau à changement de phase organique de type solide-solide, à base de polyuréthane, le procédé comprenant: -une étape (i) de mélange et réaction d'un polyéthylène glycol liquide, d'un réticulant et d'un polyisocyanate liquide, par agitation mécanique,à une première température contrôlée,dans une enceinte, pour obtenir le polyuréthane liquide, -une étape (ii) de cuisson du polyuréthane liquide, à une deuxième température contrôlée, pour rendre le polyuréthane solide, le mélange de l'étape (i) étant effectué en l'absence de solvant.
