Through the addition of expanded graphite (EG) to polyethylene glycol, the authors were able to enhance the thermal conductivity of the phase change material (PCM). The transient plane source (TPS) technique was used to measure the thermal conductivity of the PCM. The amount of EG affected thermal conductivity, while amount of polyethylene glycol affected latent heat. Through the use of EG, the thermal conductivity was raised fourfold.....
An organic phase change material (PCM), tetradecanol (TD), infused with copper nanowires (CuNWs), was sent through a slurry of tests, to determine the effect of the ultra-high aspect ratio and sponge nature of the CuNWs, on the PCM. Experimental testing alluded to the increased thermal conductivity of the PCM, with the addition of the CuNWs. The addition of CuNWs, enhanced the thermal conductivity of the PCM by nearly 9 times. A ...
Increasing the thermal conductivity of an organic phase change material, all the while maintaining a high phase change enthalpy, is a difficult task. In this study, researchers took 1-tetradecanol/Ag nanowires composites, containing various wt% of Ag nanowires, and tested their thermal conductivities and phase change enthalpies. The results suggest the PCM composite containing 62.73 wt% of Ag nanowires is the most promising candidate for thermal conductivity enhancement of organic phase ...
