Enhanced heat capacity ofAg immobilized core/shell n-octadecane/polyureananoparticlesafter centrifuge method |
| 초록 |
Silver nanoparticles immobilized polyurea particles containg the PCM were synthesized by miniemulasion polymerization. Moreover to maximize the response rate, silver nanoparticles are immobilized the shell of PCM particles. The particles prepared with different parameters were investigated in terms of latent heat storage of encapsulated n-octadecane as PCM. The morphology and particle features of PCM particles were analyzed by scanning electron microscope and transmission electron microscope, respectively. The stable and spherical PCM particles of nano-size were obtained by miniemulsion polymerization, and silver nano-particles were immobilized on the particles well. Thermal properties of fabricated particles were studied by differential scanning calorimetry. From DSC freeze-thaw cycle, the particles exhibited the thermal energy storage and release behaviors. We expect the fabricated capsules have a good potential as thermal energy storage medium. |
