Preparation of Enhanced Latent Heat Storage Electrospun Polyethylene Oxide Nanofibers using Octadecane/Polyurea Core/Shell Nanoparticles |
| 초록 |
Latent heat storage polyethylene oxide nanofibers (LHS-PEO nanofibers) with Octadecane/Polyurea (PCM/PU) core/shell nanoparticles were successfully prepared using electrospinning method. When the solid content of PCM/PU latex is increased, the content of PEO is relatively decreased. And at this time, inside PEO nanofibers, hole is produced. Therefore, the number of PCM/PU nanoparticles which is embedded is decreased. As a result, latent heat capacity of LHS-PEO nanofibers dwindle. It can be demonstrated by Transmission Electron Microscopy, Time-Temperature curve, Strain-Stress curve and Young’s modulus. The weight percent of embedded PCM/PU core/shell nanoparticles and encapsulation efficiency in the PEO nanofibers according to the solid content of PCM/PU latex was calculated by a various parameters and equations. |
