Currently, phase change materials (PCMs) composite fibers are typically prepared by electrospinning. However, electrospinning exhibits safety concerns and a low production rate, which limit its practical applications as a cost-effective fiber fabrication approach. Therefore, a novel, and simple centrifugal spinning technology is employed to extrude fibers from composite solutions using a high-speed rotary and perforated spinneret. The composite fibers based on polyvinylpyrrolidone (PVP) and polyethylene glycol (PEG) were prepared by centrifugal spinning. The SEM of PVP/PEG composite fibers indicated that the fibrous morphology is well preserved. The DSC and TGA indicated that PVP/PEG composite fibers exhibit good thermal properties.

当前，相变材料（PCM）复合纤维通常通过电纺丝制备。然而，静电纺丝存在安全性问题和低生产率，这限制了其作为成本有效的纤维制造方法的实际应用。因此，采用一种新颖，简单的离心纺丝技术，可以使用高速旋转和穿孔喷丝板将纤维从复合材料溶液中挤出。通过离心纺丝制备了基于聚乙烯吡咯烷酮（PVP）和聚乙二醇（PEG）的复合纤维。PVP / PEG复合纤维的SEM表明纤维形态被很好地保留。DSC和TGA表明PVP / PEG复合纤维表现出良好的热性能。
