PANI/tetradecanol/MWNTs composites were prepared via in-situ polymerization and analyzed for their use as phase change materials. The MWNTs were randomly dispersed in the composite and it was determined that the PCM was form-stable and that phase separation of the MWNTs and PANI/tetradecanol wouldn't occur....

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 ...

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 ...

The Transient Plane Source method was used in this research article to measure the thermal conductivity of an Ionanofluid, highly stable graphene (GE)-based nanofluid, at various temperatures. Researchers took special note of the effects of temperature, GE loading, presence of multi-walled carbon nanotubes (MWCNTs), on the thermal conductivity of the nanofluid. Through experimental testing, it was determined that the nanofluid elicited a higher thermal conductivity, as compared to its ...

This research proposed a new, flame retardant, shape-stabilized phase change material (PCM), for use in thermal energy storage. Typical paraffin and high-density polyethylene has great shape retention, however is highly flammable and has a low thermal conductivity. Researchers introduced expanded graphite and an intumescent flame retardant to the mix to improve the thermal properties and flammability, respectively. After several tests, including a thermal conductivity evaluation, on multiple variations of the ...
