Paraffinic PCM
microcapsules

The surface morphology as obtained by the SEM (front view) of the PCM-coated
fabric material is shown in Fig. 4.12. The PCM microcapsules are distinctly visible
on the surface of the fabric as shown in the figure.
The surface morphology as obtained by the SEM (back view) of the PCMcoated fabric material is shown in Fig. 4.13. The PCM microcapsules were observed
sparingly on the back surface of the fabric, as the cross section is thin.
