However, the effects of polyester molecular weight and end groups on ionic conductivity of polymer solid‐state electrolytes have been less studied. In this work, poly (hexamethylene succinate) (PHS) with various molecular weights and PHS‐based electrolytes with 30 wt% bis(trifluoromethane)‐sulfonimide lithium salt (LiTFSI) were prepared. From Raman spectra, PHS/LiTFSI with more end carboxyl groups of 5.3 × 10<sup>-5</sup> mol/g had the highest LiTFSI dissociation rate up to 68.8 % at room temperature, due to the strong binding between end carboxyl groups and Li<sup>+</sup>. Both the glass transition temperature and crystallinity of PHS/LiTFSI exhibited a characteristic convex profile with minimum values occurring at − 48.1°C and 8.32 %. It is suggested that more amorphous regions dilute the Li<sup>+</sup> concentration which weakens the interactions of ions and polymer segments and restricts chain mobility. The ionic conductivity from electrochemical impedance spectroscopy confirmed that the relationship between molecular weight and ionic conductivity followed the fractional linear function, indicating the importance of tailoring solvation capacity and the dominant ion transport mechanism.</div></div>","PeriodicalId":384,"journal":{"name":"Materials Letters","volume":"398 ","pages":"Article 138882"},"PeriodicalIF":2.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, medium-entropy alloy (MEA), especially CoCrNi, doesn’t have the desirable yield strength. In order to address this issue, the nano-TiC particles were utilized as reinforcement agents to enhance the mechanical performance of CoCrNi-based alloy metamaterials in this work. Compressive performance of the proposed metamaterial was investigated through experimental and numerical simulation methods. The experimental findings indicate that the incorporation of TiC significantly improves the mechanical properties of CoCrNi-based octet-plate metamaterials, Specifically, the strength and energy absorption of metamaterials with 3% TiC increase by 60% and 25%, respectively, compared to those of CoCrNi metamaterials. The failure mechanism exhibits an ideal layer-by-layer collapse mode, accompanied by localized buckling instabilities. Numerical results show that, as the fraction of TiC increases from 0% to 5%, the strength and energy absorption of metamaterials increase by 108% and 118%, respectively. Furthermore, comparing with the additively manufactured metamaterials with octet-plate/truss unit cells, CoCrNi-TiC metamaterials exhibit superior mechanical properties at the same relative density.</div></div>","PeriodicalId":384,"journal":{"name":"Materials Letters","volume":"398 ","pages":"Article 138873"},"PeriodicalIF":2.7,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
