Abstract: Composite phase change materials were prepared using stearic acid, coffee grounds, and graphite. The coffee grounds were used as a supporting material for the stearic acid, and the graphite was added in an effort to enhance the thermal conductivity of the composite. The composites were characterized by SEM and FT-IR, the thermal conductivity was determined by the phase change temperature and latent heat were determined by differential scanning calorimetry. The addition of the graphite enhanced the thermal conductivity by 53% in comparison to stearic acid/coffee grounds.
