A comprehensive analysis showed that TiO2NPs content has a significant effect on the structure formation processes in the polymer matrix, the degree of crystallinity, phase composition, and surface morphology of the composites. By optimizing the amount of doped nanoparticles, it is possible to increase the electrical strength and permittivity of the material, as well as enhance the piezoelectric response compared to a film without TiO2NPs. The introduction of TiO2NPs into the P(VDF\/TFE) polymer matrix promotes efficient polarization of the composite film without preliminary high-temperature orientational drawing. The approaches presented in this study can simplify process operations in the manufacture of flexible sensors, wearable electronics, and other devices that require a combination of piezoelectric activity and high electrical strength.<\/jats:p>","DOI":"10.3390\/ijms27188018","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T10:19:16Z","timestamp":1788949156000},"page":"8018","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Amorphous TiO2 Nanoparticles on the Crystalline Structure and Functional Properties of P(VDF-TFE) Nanocomposites"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1556-7635","authenticated-orcid":false,"given":"Andrey A.","family":"Vodyashkin","sequence":"first","affiliation":[{"name":"Bauman Moscow State Technical University, 2-\u044f Baumanskaya St., 105005 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"}]},{"given":"Evgenia L.","family":"Buryanskaya","sequence":"additional","affiliation":[{"name":"Bauman Moscow State Technical University, 2-\u044f Baumanskaya St., 105005 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4217-2022","authenticated-orcid":false,"given":"Polina M.","family":"Tyubaeva","sequence":"additional","affiliation":[{"name":"Academic Department of Technology and Chemistry of Innovative Materials, Plekhanov University of Economics, 117997 Moscow, Russia"},{"name":"Department of Biological and Chemical Physics of Polymers, Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, 4 Kosygina Street, 119334 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Dmitriy S.","family":"Ryzhenko","sequence":"additional","affiliation":[{"name":"Bauman Moscow State Technical University, 2-\u044f Baumanskaya St., 105005 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8945-3919","authenticated-orcid":false,"given":"Mstislav O.","family":"Makeev","sequence":"additional","affiliation":[{"name":"Bauman Moscow State Technical University, 2-\u044f Baumanskaya St., 105005 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101571","DOI":"10.1016\/j.mtchem.2023.101571","article-title":"Piezoelectric performance of electrospun PVDF and PVDF composite fibers: A review and machine learning-based analysis","volume":"30","author":"Chen","year":"2023","journal-title":"Mater.
