In this work, a phase-change energy storage nonwoven fabric was made of polyurethane phase-change material (PUPCM) by a non-woven melt-blown machine. Polyethylene glycol 2000 was used as the phase transition unit and diphenyl-methane-diisocyanate as the hard segment to prepare PUPCM. Thermal stability of the PUPCM was evaluated through thermal stability analysis. The performance of pristine PUPCM was determined by Fourier transform infrared spectroscopy and differential scanning calorimetry to analyze the spinning technology of spinning temperature and the stretching process. Phase-change energy storage nonwoven fabric (413.22 g/m2) was prepared, and the morphology, solid–solid exothermic phase transition, mechanical properties, and the structures were characterized. The enthalpy of solid–solid exothermic phase transition reached 60.17 mJ/mg (peaked at 23.14°C). The enthalpy of solid–solid endothermic phase transition reached 67.09 mJ/mg (peaked at 34.34°C). The strength and elongation of phase-change energy storage nonwoven fabric were found suitable for garments and tent fabrics.

相变储能无纺布的制备与表征

在这项工作中,通过无纺布熔喷机将聚氨酯相变材料(PUPCM)制成相变储能无纺布。以聚乙二醇2000为相变单元,二苯基甲烷二异氰酸酯为硬链段制备PUPCM。PUPCM 的热稳定性通过热稳定性分析进行评估。通过傅里叶变换红外光谱和差示扫描量热法测定原始PUPCM的性能,分析纺丝温度和拉伸工艺的纺丝工艺。相变储能无纺布(413.22 g/m 2),并表征了形态、固-固放热相变、机械性能和结构。固固放热相变焓达到 60.17 mJ/mg(峰值为 23.14°C)。固固吸热相变焓达到 67.09 mJ/mg(峰值为 34.34°C)。相变储能非织造布的强度和伸长率被发现适用于服装和帐篷织物。
