英文摘要	Mesophase pitch based graphite foams (gfs) with different thermal properties and pore-size were used to increase the thermal diffusivity of phase change material (pcm), paraffin wax, for latent heat thermal energy storage application. to predict the performance of the paraffin-gfs as a thermal energy storage system, their structure, thermal diffusivity and latent heat were characterized. results indicated that thermal diffusivity of the paraffin-gf can be enhanced 190, 270, 500, and 570 times as compared with that of pure paraffin wax. latent heat of paraffin-gf systems increased with the increasing of the mass ratio of the paraffin wax in the composite. moreover, pore-size and thickness of ligaments of the foam played a key role in improving the thermal diffusivity and the storage capacity of the paraffin-gf system: small pore-size (less paraffin wax were filled) and thicker ligament in gf resulted in a higher thermal diffusivity; large pore-size (less paraffin wax were filled) and thinner ligament in gf resulted in a larger latent heat.
