Preparation and thermal properties of polyethylene glycol/expanded graphite blends for energy storage

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.....

Enhanced thermal conductivity and thermal performance of form-stable composite phase change materials by using B-Aluminum nitride

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 ...

A novel sebacic acid/expanded graphite composite phase change material for solar thermal medium-temperature applications

Sebacic acid (SA) can be absorbed into the pores of expanded graphite (EG) to form a SA/EG composite phase change material (PCM). There is no chemical interaction between the SA and EG, they are merely integrated. The optimal amount of SA was found to be 85 wt.% of the total mixture. The 85 wt.% composite had a phase change temperature of ~ 128°C, with a latent heat of ~ 187 J/g. The thermal ...

Thermal conductivity enhancement of MWNTs on the PANI/tetradecanol form-stable PCM

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....

Graphene-enhanced hybrid phase change materials for thermal management of Li-ion batteries

In this article, researchers aim to improve the thermal management of Li-ion batteries, by introducing graphene fillers to hybrid phase change materials. The thermal management of any battery is dependent on the latent heat stored within the phase change material as it transitions phases. During this time, it is also crucial to reduce the chances of an internal temperature rise. Researchers used a thermal analyzer to determine the thermal conductivity ...
