![]() ![]() PCMs are able to absorb and release large amounts of latent heat according to the increase and decrease in the temperature of the surroundings. One of the most significant discussions in energy storage is the use of the Phase Change Materials (PCM) for thermal energy storage. Therefore, microencapsulated paraffin wax/polyaniline is a stable material that can be used for thermal energy storage systems. Besides, the chemical characteristics and structural profile remained constant after one thousand thermal cycling tests. It has been found that the microencapsulated paraffin waxes show little change in the latent heat of fusion and melting temperature after one thousand thermal recycles. Structure stability and compatibility of core and coating materials were also tested by Fourier transform infrared spectrophotometer (FTIR), and the surface morphology of the samples are shown by Field Emission Scanning Electron Microscopy (FESEM). Thermal properties of microencapsulated paraffin wax were evaluated by Differential Scanning Calorimeter (DSC). These samples were then subjected to a thermal cycling test. The microencapsulated samples with 23% and 49% paraffin showed less decomposition after 330 ☌ than with higher percentage of paraffin. Weight losses of samples were determined by Thermal Gravimetry Analysis (TGA). ![]() Microencapsulated paraffin wax/polyaniline was prepared using a simple in situ polymerization technique, and its performance characteristics were investigated.
