bending and C-O-C stretching. These results align with the findings of Lisa Boussaba et al. (2018). Comparing the FT-IR spectrum of the Ceno-based PCM with that of the synthesized composite-PCM (Figure 5), it is clear that the peak shapes remain unchanged in the composite-PCM. This indicates that no changes occurred in the peak positions of the Ceno-based PCM, suggesting that only physical interactions, and not chemical interactions, are present between the Ceno-based PCM and its supporting material.
