Through fiber encapsulation, shape-stable phase change materials can be prepared, thereby expanding their applications. In this study, electro-blown spinning was utilized to prepare phase change materials (PCM) using erythritol, with polyethylene oxide (PEO) as the carrier material. Coaxial thermal storage fibers encapsulating the phase change materials were prepared using polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP). The results indicate that the composite fibers have a smooth surface, uniform and smooth morphology, a maximum latent heat of 223.01 J\/g, as well as excellent thermal stability. The coaxial fibers exhibit a distinct core\u2013shell structure, with the coaxial fibers encapsulated with PVA as the shell material, demonstrating a high latent heat of 118.62 J\/g, a residual rate of 93.81% after heating, and excellent thermal performance. The encapsulation efficiency is 53%, effectively addressing the issue of erythritol leakage. The research results provide valuable guidance for the efficient preparation of erythritol coaxial thermal storage fibers.<\/jats:p>","DOI":"10.3390\/polym18080923","type":"journal-article","created":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T09:08:12Z","timestamp":1775812092000},"page":"923","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Preparation and Properties of Electro-Blown Spinning Erythritol-Based Coaxial Phase Change Fibers"],"prefix":"10.3390","volume":"18","author":[{"given":"Jiaxi","family":"Yang","sequence":"first","affiliation":[{"name":"Northern United Power Co., Ltd., Hohhot 010020, China"},{"name":"School of Renewable Energy, Inner Mongolia University of Technology, Erdos 017010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-0720-648X","authenticated-orcid":false,"given":"Bingnan","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Inner Mongolia University of Technology, Hohhot 010051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanxiong","family":"Qiao","sequence":"additional","affiliation":[{"name":"Northern United Power Co., Ltd., Hohhot 010020, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiguo","family":"Ma","sequence":"additional","affiliation":[{"name":"Northern United Power Co., Ltd., Hohhot 010020, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuanxi","family":"Qiao","sequence":"additional","affiliation":[{"name":"Northern United Power Co., Ltd., Hohhot 010020, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zehao","family":"Wang","sequence":"additional","affiliation":[{"name":"Xilingol Thermal Power Plant of Northern United Power Co., Ltd., Xilingol 026000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heqiang","family":"Zheng","sequence":"additional","affiliation":[{"name":"Dalat Power Plant of Northern United Power Co., Ltd., Ordos 017010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiqiang","family":"Bian","sequence":"additional","affiliation":[{"name":"Dalat Power Plant of Northern United Power Co., Ltd., Ordos 017010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Renewable Energy, Inner Mongolia University of Technology, Erdos 017010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunguang","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Renewable Energy, Inner Mongolia University of Technology, Erdos 017010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Inner Mongolia University of Technology, Hohhot 010051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9084-6776","authenticated-orcid":false,"given":"Ding","family":"Nan","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Inner Mongolia University, Hohhot 010021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1016\/j.cep.2016.08.003","article-title":"Towards improving charge\/discharge rate of latent heat thermal energy storage (LHTES) by embedding metal foams in phase change materials (PCMs)","volume":"108","author":"Du","year":"2016","journal-title":"Chem.
