Nanoencapsulation of n-Tetradecanol Phase Change Material by In-Situ Polymerization for Thermal Energy Storage

Abstract

In this study, it was intended at preparing and characterization of urea-formaldehyde shell nano capsules containing n-tetradecanol as phase change materials (PCMs) for thermal energy. The tetradecanol microcapsules were branded by using scanning electron microscope (SEM),differential scanning calorimeter, thermal gravimetric analysis (TGA). The contents of tetradecanol in microcapsules, the latent heats of melting and solidification, and thermal stability are shown in test result. Thermal cycling test depict that the microcapsules have good reliability with respect to the acceleration ofthermal cycling. Based on the results, it can be considered that the microencapsulated tetradecanol have better energy storage potential.
