The influence of various concentrations of PVA solutions on the barrier (vapor permeability) and physicomechanical properties of the films is examined. The fracture strength increases, the relative elongation decreases markedly, and the permeability of the polymer increases sharply with an increase in the glycerol concentration in PVA. The introduction of 20–30% plasticizer into PVA results in the formation of a sufficiently elastic film: the relative elongation to failure increases, and the ultimate tensile strength decreases.</p>","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 8","pages":"1789 - 1796"},"PeriodicalIF":0.4000,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":"0","resultStr":null,"platform":"Semanticscholar","paperid":null,"PeriodicalName":"Russian Metallurgy (Metally)","FirstCategoryId":"5","ListUrlMain":"https://link.springer.com/article/10.1134/S0036029525700326","RegionNum":0,"RegionCategory":null,"ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":null,"EPubDate":"","PubModel":"","JCR":"Q4","JCRName":"METALLURGY & METALLURGICAL ENGINEERING","Score":null,"Total":0}
