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":"2025-09-06","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}

The as-deposited films at room temperature exhibited an amorphous structure, which underwent a phase transition to a polycrystalline state upon annealing at 800 K. This annealing process resulted in a significant reduction of surface defects and the formation of a continuous film composed of nanocrystallites with dimensions in the range of 50–100 nm. The presence of the SiO<sub>2</sub> dielectric layer on the substrate induced distinct variations in the film’s microstructure and density, which in turn affected its electrical resistivity and thermoelectric performance. The enhancement of thermoelectric properties observed during the amorphous-to-crystalline phase transition is attributed to the selective scattering mechanism of charge carriers at nanocluster boundaries.

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.
