of the PCM at 4 C and 25 C together with the porous structures of
the PCL fibres and the PCL protection layer (without PCM). In fact,
PS-multilayer structures stored at 4 C significantly decreased
the encapsulation efficiency with the storage time when the
PCL/PCM layer was not protected by a PCL layer.
From the results, it can be concluded that the greatest heat storage capacity was achieved for PS multilayer structures prepared
with both layers PCL/PCM and PCL, stored at 4 C, which retained
the encapsulated RT5 during the storage.
