Abstract: |
To improve the low conductivity of Phase Change Materials (PCM), MSGF / paraffin composites were prepared by mixing MSGF into melted paraffin, which was exfoliated from Expanded Paraffin (EG). The structure and thermal properties of the composites were characterized by means of SEM, Hot Disk, and DSC. The Infrared Heat Camera was used to observe the temperature distribution in solidification process. The experimental results show that the stable heat exchanger network was formed in composites by MSGF, making the speed of heat storage raised and the chemical properties stable. Meanwhile, the latent heat capacity show negligible decrease.
