제목 | The Phase Change Capsule with Water-absorbable Polymeric Shell for Thermal Energy Storage and Delivery |
초록 | The phase change capsules (PCCs), which can deliver the thermal energy by storing the latent heat from solar heat, have been highlighted as one of the solutions for reducing the amount of energy consumption. In this work, we used Pickering emulsion based encapsulation method in order to enhance the core content for high thermal energy capacity, and encapsulated the phase change material (PCM) with water-absorbable polymeric shell to enhance the thermal conductivity. Paraffin wax was used as core thanks to its high heat storage capacity and nontoxic properties. And the poly(2-hydroxyethyl methacrylate) (pHEMA), a water-absorbable polymer, was used as a shell because the pHEMA can show high thermal conductivity after absorbing a water. The thermal conductivity of fully hydrous pHEMA was measured to be 0.45 W/m·K which is far higher than the other polymers, and the thermal storage capability of the PCC was calculated to be 99.7%, which is higher than previously researched other PCCs. |
