The goal of this work was to produce a new high performance PCM, using a combination of RT 100 (paraffinic hydrocarbons) with expanded graphite (EG). The resulting composite performed extremely well in quality testing. Thermal conductivity was measured using the TPS method, and was found to be much higher in the composite than it was in the basic RT 100 materials. Thermal conductivity did not decrease during melting cycles. The ability of ...
A new composite phase change material for cold thermal energy storage applications is described in this paper. The authors combined dodecane into hydrophobic fumed silica to create a form stable PCM. Physical characteristics were studied using scanning through electron micrographs and Fourier transformation infrared. A thermal analyzer was used to measure the thermal conductivity of the composite, which was a desired low value needed for this type of application. An ...
