Form-stable composite phase change materials (PCMs) for use in wallboards were prepared by absorbing stearic acid (SA) and lauric acid (LA) eutectic mixtures into the pores of expanded perlite (EP) via vacuum impregnation.
In this paper, novel composite phase change materials (PCMs) were prepared by absorbing stearic acid (SA) into sepiolite (α-sepiolite, β-sepiolite) via a vacuum impregnation method.
