Abstract

In this paper, an electrospinning composite material for solar energy storage was prepared by combining 2-methyl-acrylic acid 6-[4-(4-methoxy-phenylazo)-phenoxy]-hexyl ester (MAHE) as molecular solar thermal (MOST) molecule and polyethylene glycol-2000 (PEG) as phase change material (PCM) using electrospinning technique for the first time. In the composite fibers, both kinds of energy storage molecules successfully carried out energy storage and release behavior, and the enthalpy value reached 11.623 J/g. MAHE molecule in the composite showed good fatigue resistance in the reversible charge and discharge process within 50 cycles. It is more noteworthy that the materials obtained by electrospinning have excellent leakage resistance. The experimental results show that electrospinning has a wide development potential in the preparation of solar energy storage materials.

通过在静电纺丝纤维中加入分子太阳能热（MOST）分子和相变材料（PCM）来提高储能性能

本文首次采用静电纺丝技术，以2-甲基丙烯酸6-[4-（4-甲氧基苯基偶氮）-苯氧基]-己基酯（MAHE）为太阳热分子（MOST），聚乙二醇-2000 （PEG）为相变材料（PCM），制备了一种用于太阳能储能的静电纺丝复合材料。在复合纤维中，两种储能分子都成功地进行了储能和释放行为，焓值达到11.623 J/g。复合材料中的MAHE分子在50次循环的可逆充放电过程中表现出良好的抗疲劳性能。更值得注意的是，静电纺丝得到的材料具有优异的防漏性能。实验结果表明，静电纺丝在制备太阳能储能材料方面具有广阔的发展潜力。图形抽象
