    Thermal characterization of phase change materials based on linear low-density polyethylene, paraffin wax and expanded graphite by Sobolciak, Patrik

    Published 2016
    “…The storage and release of thermal energy during phase change which is associated with the latent heat of the materials were investigated within the temperature range 20–50 °C. PCMs containing 40 wt.% of paraffin wax exhibited latent heat of 36 J/g, whereas the latent heat of PCMs containing 50 wt.% of paraffin wax was 49 J/g. …”
