To improve the thermal conductivity of polymeric matrixes, conducting fillers were added to polymers, specifically graphite, having good thermal conductivity and dispersibility. Exfoliated graphite (EG) and graphite nanoplatelets (GNP) are excellent alternatives to metal and carbon as conductive polymer composites, through solution mixing and melt blending techniques. Thermal conductivity of composites was measured by a thermal analyzer, using the transient plane source (TPS) method. Solid-state shear milling treated composites showed ...
Low-temperature expandable graphite (LTEG) was blended into low-density polyethylene (LDPE) to prepare composite materials with an enhanced thermal conductivity in comparison to pure LDPE. The thermal conductivity of a composite containing 60 wt. % LTEG was found to be increased by a factor of 23 in comparison to the pure polymer. The LTEG was also found to decrease the melting temperature and degree of crystallinity of the LDPE, and the composites were also ...
HVAC systems have become very popular, but require a lot of thermal storage. One way to provide this storage is through phase change materials (PCM). This report investigates using expanded graphite to improve the thermal conductivity of a capric, lauric and oleic acid mixture PCM. It was found that with the increase in mass fraction of expanded graphite the thermal conductivity of the PCM also increases....
