Abstract With the rapid development of society, all kinds of non-renewable energy resources are constantly developed and utilized, energy storage is one of the best ways to solve the energy shortage. In this study , levulinic acid (LA) and 1,4 butanediol (BDO) were used to synthesize a novel polyol ester (LABDO) by biological and chemical methods. The biological method exhibited excellent performance in the synthesis process, where 87.5% of LABDO yield under optimal conditions, while the chemical method had more byproducts and higher energy consumption. Finally, the thermal properties of the obtained phase change materials (PCMs) were evaluated. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) showed that the melting temperature of LABDO was 50.51°C, the latent heat of melting was 156.1J/g, and the pyrolysis temperature was 150-160°C. Compared with traditional paraffin wax, the prepared PCMs have suitable phase transition temperature, higher latent heat of melting and better thermal stability. The thermal conductivity can be increased to 0.34W·m-1· k-1 by adding expanded graphite. In summary, LABDO can be used as low temperature phase change energy storage materials.

To solve the issues of flowing and leaking of myristic acid (MA) as phase change energy storage material in practical application, a novel microencapsulated composite phase change energy storage material was prepared by sol-gel method using myristic acid (MA) as core material and titanium dioxide (TiO2) as shell material. The chemical structure, crystal structure, micromorphology, phase change characteristics and thermal stability of phase change microencapsulated energy storage materials were characterized by using Fourier transform infrared spectrometer (FT-IR), X-ray diffraction analyzer (XRD), field emission scanning electron microscope (FE-SEM), differential scanning calorimetry (DSC), thermogravimetric analyzer (TGA). The consequents illustrated that the ideal sample melted at 54.97 °C with the latent heat of 55.76 J/g and solidified at 49.85 °C with the latent heat of 54.55 J/g. In general, the prepared microencapsulated phase change materials possessed good thermal properties and thermal stabilities. It is predicted that the shape-stabilized MA/TiO2 composites have great potential for thermal energy storage.
