The synthesized MEPCMs have been characterized by XRD, ATR-FTIR, TGA, DSC, DLS, leakage test, and FE-SEM analysis.</div></div><div><h3>Significant findings</h3><div>The MEPCM-6 shows the phase change enthalpy as 70.3 J g<sup>-1</sup> and 60.7 J g<sup>-1</sup>, for the melting and freezing process, respectively. The optimized MEPCM has been applied to leather for developing thermoregulation properties on leather. MEPCMs-coated leathers show up to 2.6 °C lower and 2.2 °C higher temperature difference than control leather in hot and in cold conditions, respectively.</div></div>","PeriodicalId":381,"journal":{"name":"Journal of the Taiwan Institute of Chemical Engineers","volume":"171 ","pages":"Article 106060"},"PeriodicalIF":5.5,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
