英文摘要 | This study focuses on the design and synthesis, thermal energy storage properties and thermal stability of a novel thermoplastic polyurethane solid solid phase change material (PUSSPCM) for thermal energy storage. The PUSSPCM was synthesized via the two-step condensation reaction of 4,4'-diphenylmethane diisocyanate, polyethylene glycol and a novel tetrahydroxy compound (terephthalic acid bis-(2-hydroxy-1-hydroxymethyl-ethyl) ester) and characterized by Fourier transform infrared spectroscopy and H-1 nuclear magnetic resonance techniques. Thermal energy storage properties and thermal stability of assynthesized PUSSPCM were also measured. DSC results indicate that the phase change temperatures and latent heats of the as-synthesized PUSSPCM are in the ranges of 22.4-48.4 degrees C and 143.9-153.5 J/g, respectively. TGA results confirm that the initial degradation temperature of the PUSSPCM is at 323 degrees C, which proves that PUSSPCM has good thermal stability. More significantly, the as-synthesized PUSSPCM can be directly melted and processed, and has a wide processing temperature range. Based on these results, it can be concluded that the synthesized PUSSPCM, as a novel phase change material (PCM), has significant energy storage potential due to its suitable phase change temperatures, higher latent heats, good thermal stability and processing performances.
