To develop PVDF-based solutions, different protocols are reported in the literature; however, a toxic and harmful solvent is commonly used (dymethilformamide (DMF)). In the present study, a non-toxic solvent (dymethilsulfoxide (DMSO)) is used to dissolve PVDF powder, while a specific ionic liquid (IL), [PMIM][TFSI], is used to enhance piezoelectric properties. A PVDF\/IL thin film is characterized. The physical material characterization is based on optical analysis (to ensure the sample\u2019s homogeneity) and on mechanical linear behaviour (Young\u2019s modulus of 144 MPa and yield stress of 9 MPa). Meanwhile, a chemical analysis focuses on the phase modifications introduced by the addition of IL (\u03b2 phase increase to 80% and a degree of crystallinity, \u03c7, of 30%). All the results obtained are in good agreement with the literature, which indicates that the proposed experimental protocol is suitable for producing PVDF-based thin films for biomedical applications.<\/jats:p>","DOI":"10.3390\/app14083356","type":"journal-article","created":{"date-parts":[[2024,4,17]],"date-time":"2024-04-17T08:22:44Z","timestamp":1713342164000},"page":"3356","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Influence of DMSO Non-Toxic Solvent on the Mechanical and Chemical Properties of a PVDF Thin Film"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3854-8632","authenticated-orcid":false,"given":"Ant\u00f3nio Diogo","family":"Andr\u00e9","sequence":"first","affiliation":[{"name":"Associated Laboratory of Energy, Transports and Aeronautics (LAETA), Biomechanic and Health Unity (UBS), Institute of Science and Innovation in Mechanical and Industrial Engineering (INEGI), 4200-465 Porto, Portugal"},{"name":"Faculty of Engineering, University of Porto (FEUP), 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3221-5762","authenticated-orcid":false,"given":"Ana Margarida","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Associated Laboratory of Energy, Transports and Aeronautics (LAETA), Biomechanic and Health Unity (UBS), Institute of Science and Innovation in Mechanical and Industrial Engineering (INEGI), 4200-465 Porto, Portugal"},{"name":"Faculty of Engineering, University of Porto (FEUP), 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9732-4498","authenticated-orcid":false,"given":"Pedro","family":"Martins","sequence":"additional","affiliation":[{"name":"Associated Laboratory of Energy, Transports and Aeronautics (LAETA), Biomechanic and Health Unity (UBS), Institute of Science and Innovation in Mechanical and Industrial Engineering (INEGI), 4200-465 Porto, Portugal"},{"name":"Aragon Institute for Engineering Research (i3A), Universidad de Zaragoza, 50018 Zaragoza, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1080\/10584587.2020.1803672","article-title":"A Review on Applications of Piezoelectric Materials in Aerospace Industry","volume":"211","author":"Elahi","year":"2020","journal-title":"Integr.
