Phase change materials and applications

In the first step of the work, which are placed in two steps, camphene-palmitic and camphene-stearic acid and mixtures have been prepared by using camphene, stearic acid and palmitic acid with different rates. The main eutectic mixtures have been selected from these prepared two series which have the best structural and thermal properties. In the second stage, fly ash, pyroclastic, marble powder and barite have been doped to the these selected mixtures. The obtained composite based PCM's structural and thermal properties have been analysed by using DSC, FT-IR, TGA and SEM techniques.
