Through the addition of different amounts of thermally conducting B-Aluminum nitride powder to polyethylene glycol and silica gel a form-stable phase change material (PCM) is prepared. Using the Thermal Constants Analyzer, the researchers were able to measure the thermal conductivity of the PCMs. Increasing amounts of B-Aluminum nitride powder results in increasing thermal conductivity, but a decrease in the value of the latent heat. Melting temperatures were unaffected by the ...
The low thermal conductivity of paraffin hinders its ability to be used as a PCM, and so in this article the authors created a composite made up of paraffin and micron-size graphite flakes (MSGFs) in order to hopefully increase thermal conductivity and energy storage capabilities. The results showed that increasing concentrations of MSGFs corresponded to 'enormous' increases in thermal conductivity. The addition of MSGFs to paraffin did not affect its ...
