It can be seen from the table that the fabricated composite PCM has comparable latent heat values with some of the reported ones.
It is known that the texture and microstructure of expanded vermiculites, the thermal properties of organic PCMs and even the fabrication methods are all the factors that can potentially affect the organic PCM impregnation percentages and the resultant thermal properties of fabricated composite PCMs.
These are the causes for the observed differences in Table 3.
