Preparation and Research of Phase Change Material Based EVA / Binary Fatty Acids Composite

Abstract:

In this study, melting method is adopted for the preparation of phase change material based EVA /binary fatty acids composite. Phase change temperature and latent heat of the binary fatty acids and EVA /binary fatty acids composite are characterized using Differential Scanning Calorimetry (DSC). The structure and thermal insulation properties of the binary fatty acids and EVA /binary fatty acids composite are investigated using Fourier transformation infrared spectroscope (FTIR) and temperature-recording instrument. The DSC results show that Phase change temperature and latent heat of the binary fatty acids are less than that of pure Stearic Acid and Lauric Acid, The latent heat of EVA /binary fatty acids composite are increase with the increasing of the binary fatty acid content. Cooling curves show that the binary fatty acid and EVA /binary fatty acids composite have good insulation properties. The FTIR results show that EVA and binary fatty acid are combined by intermolecular forces.
