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 Hot Disk method, 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.
