Through the addition of graphite powder (GP) and expanded graphite (EG) the authors were able to increase the thermal conductivity of a shape-stabilized paraffin/high density polyethylene (HDPE) composite phase change material (PCM). GP and EG were added in different mass fractions and a Thermal Constants Analyzer was used in order to measure the thermal conductivity. The relationship between mass fractions of GP and EG added were found to have ...
In this article, the transient plane source technique was used to determine the effect of iron, a flame retardant shape-stabilized phase change material (FSPCM), on the thermal conductivity of a sample of paraffin/high-density polyethylene (HDPE). With the results, it was determined that iron could be dispersed within the HDPE and paraffin samples, so as to improve the flame retardant efficiency. The results also concluded that the thermal conductivity of ...
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 ...
The objective of this study was to create polymer composites with high thermal conductivity and mechanical properties. To acquire these, aluminum nitride microparticles were modified with a titanate coupling reagent of isopropyltrioleictitanate, and blended via a power-mixing method into linear low-density polyethylene. Using a thermal constants analyzer, the thermal conductivity of the composite was measured. The results concluded that the addition of aluminum nitride particles to the composite enhanced the ...
