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’s homogeneity) and on mechanical linear behaviour (Young’s 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 (β phase increase to 80% and a degree of crystallinity, χ, 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. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.5 2024 ENGINEERING, MULTIDISCIPLINARY 50 / 179 = 0.279 2024 Q2 T1 CHEMISTRY, MULTIDISCIPLINARY 123 / 239 = 0.515 2024 Q3 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 284 / 461 = 0.616 2024 Q3 T2 PHYSICS, APPLIED 101 / 187 = 0.54 2024 Q3 T2 0.521 2024 Computer Science Applications 2024 Q2 Engineering (miscellaneous) 2024 Q2 Process Chemistry and Technology 2024 Q2 Instrumentation 2024 Q2 Materials Science (miscellaneous) 2024 Q2 Fluid Flow and Transfer Processes 2024 Q2 5.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Teixeira, Ana Margarida Martins, Pedro Universidad de Zaragoza (orcid)0000-0001-9732-4498 5004 605 Universidad de Zaragoza Dpto.
