In this study,we investigate wool fibers from five sheep breeds (Merino, Polwarth,Cheviot, Eider, and Devon) to elucidate how these factors influenceviscoelasticity and surface interactions. Using a multimodal approachintegrating interfacial and bulk characterization methods, includinginverse gas chromatography (IGC), atomic force microscopy-infraredspectroscopy (AFM-IR), X-ray photoelectron spectroscopy (XPS), uniaxialtensile testing, and synchrotron small-angle X-ray scattering (SAXS),we show that the nanometer-thick 18-methyleicosanoic acid (18-MEA)layer is consistently present across all wool types and plays a keyrole in governing hydrophobicity and surface heterogeneity. A controlledisothermal treatment at 200 °C, designed to cleave disulfidebonds, results in a nearly 40% reduction in specific surface areaacross all fiber types, accompanied by a significant decrease in tensilestrength and 80% reduction in elongation at break for Merino and Devonwool, but limited influence on the mechanical properties of Eiderfibers. Furthermore, rate-dependent tensile testing within the elasticregime reveals distinct viscoelastic responses among the fiber types,suggesting that the sulfur-rich protein matrix surrounding IFs andits structure contribute actively to stress partitioning. Altogether,when combined with conclusions from SAXS measurements of IF spacing,our work offers compelling insights into the role of the keratin-associatedprotein (KAP) matrix in shaping wool fiber mechanics. Differencesin mechanical behavior among wool types, despite similar IF spacingor sulfur content, highlight the importance of matrix compositionand cross-linking density, suggesting that the molecular architectureof the KAP network may be a dominant factor in determining fiber performance.</p>","PeriodicalId":29798,"journal":{"name":"ACS Materials Au","volume":"6 1","pages":"163–176"},"PeriodicalIF":9.1,"publicationDate":"2026-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145999188","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}
