Phase-change materials (PCM) are temperature-dependent substances that store and release significant latent heat energy during temperature-driven phase changes. Organic PCM, such as paraffin wax (PW), have attracted attention for their high latent heat, congruent melting/freezing temperature, nontoxicity, and availability; however, the direct utilization of PW for heat storage is limited due to low thermal conductivity and leakage during the solid-liquid phase change process. In this study, we used low-density polyethylene (LDPE), one of the commodity polymers, as a supporting material for the successful utilization of shape-stabilized PCM. We have introduced an approach for fabricating LDPE and PW (LDPE/PW) composite films, investigating the role of PW in an LDPE matrix for use as a functional packaging material with temperature-dependent gas permeability. |
