Due to the different corrosion resistance of elements and the difference in element content distribution between the two phases, the FCC phase is preferentially corroded, resulting in a three-dimensional porous morphology. This unique structure synergistically reduces the energy barrier during the hydrolysis dissociation process, giving the material a significant advantage in the oxygen evolution reaction (OER) process.

However, to date, only a few techniques have been developed to fabricate fiber composites made from these proteins. Here we present an original method of fabricating fibrous composites of collagen and elastin and characterize their mechanical behavior. Soluble elastin was electrospun to form a sheet of elastin fibers, which was rolled and submerged in an acidic solution of collagen to permit collagen infiltration. The construct was incubated at 37 °C for 1 h so that collagen fibers self-assembled into the elastin fiber network, forming an elastin/collagen fiber composite. Simultaneous application of static mechanical loading and a chemical cross-linker, genipin, to the construct for an additional 24 h was also performed for fiber alignment. SEM observation revealed that elastin and collagen fibers were well integrated, although effects of mechanical loading to align those fibers were not observed. These elastin/collagen fiber composites possessed mechanical properties between those of collagen and elastin. Tensile properties benefited from collagen, whereas viscoelastic properties were derived from elastin. This method can be applied to development of artificial replacements of load-bearing soft tissues, such as tendon and meniscus.</div></div>","PeriodicalId":18245,"journal":{"name":"Materials Letters: X","volume":"26 ","pages":"Article 100255"},"PeriodicalIF":2.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145019062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
