Objectives: The objective of this work is to study the thermal behavior of polypropylene (PP) as phase change material (PCM) with the aim of its use to store energy necessary for cooking in the event of energy deficit for the solar cooker. Method: We used the differential scanning calorimetry (DSC) method for different speeds, both heating and cooling. We have identified the phase change temperatures of the different samples as well as the evolution of the crystallinity rate of each sample. Findings: The first heating measurement of the sample is carried out to remove its thermal history. The additional heating measurements gave us information on the behavior of the material (Peak of melting: 167.24°C; Heat of fusion: 86.50 J/g). The cooling measurements gave us access to information such as the differentiation of materials with different histories. The crystallization peak of the recycled material is wider and lower than that of the new material. The temperature peaks of all the curves are around 120°C. Novelty: The use of the MCP allows us to make a solar cooker autonomous, because the energy stored at the level of the MCP, can ensure the cooking of food during the day in the absence of sunlight and also during the night.
Author Keywords: Polypropylene, Crystallization, Heater, Cooling, PCM, Store.
