Composite carbon foams were prepared by mixing tannin-based resin with various graphite powders in an effort to improve the thermal conductivity relative to pristine carbon foams in order to use them as hosts for phase-change materials. It was found that using graphite powder with smaller particle sizes resulted in foams with a higher bulk density than those prepared with an equal amount of larger graphite particles, this increased density resulted ...
In this work, the authors tested five organic phase change materials for thermophysical properties (density, heat capacity, and thermal conductivity) in order to determine the best path to prediction (BPP) for the thermal diffusivity of organic PCMs in the liquid phase. Separate BPPs were determined for alkanes and unsaturated acids. The identified BPPs were then tested on a variety of materials and the estimated thermal diffusivity was within 15% for all ...
Thermal energy storage (TES) is incredibly important to expanding the field of renewable energy. In this study, the authors look at the potential of composite phase change materials (PCMs) for use in this application. A ball milling method was used to exfoliate expanded graphite in nanosheets that could be added to eicosane to create composite materials. Composites with nanosheets of various sizes were created, and the effect of cooling rate ...
