Poly(vinylidene fluoride) (PVDF) reinforced with carbon nanotubes (CNT) or graphene with different filler contents have been developed as potential piezoresistive materials. The mechanical properties of the nanocomposites depend on the PVDF matrix, filler type, and filler content. PVDF 6010 is a relatively more ductile material, whereas PVDF-HFP (hexafluropropylene) shows larger maximum strain near 300% strain for composites with CNT, 10 times higher than the pristine polymer. This behavior is similar for all composites reinforced with CNT. On the other hand, reduced graphene oxide (rGO)\/PVDF composites decrease the maximum strain compared to neat PVDF. It is shown that the use of different PVDF copolymers does not influence the electrical properties of the composites. On the other hand, CNT as filler leads to composites with percolation threshold around 0.5 wt.%, whereas rGO nanocomposites show percolation threshold at \u2248 2 wt.%. Both nanocomposites present excellent linearity between applied pressure and resistance variation, with pressure sensibility (PS) decreasing with applied pressure, from PS \u2248 1.1 to 0.2 MPa\u22121. A proof of concept demonstration is presented, showing the suitability of the materials for industrial pressure sensing applications.<\/jats:p>","DOI":"10.3390\/ma12213545","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T05:18:26Z","timestamp":1572499106000},"page":"3545","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":53,"title":["Electromechanical Properties of PVDF-Based Polymers Reinforced with Nanocarbonaceous Fillers for Pressure Sensing Applications"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3017-4469","authenticated-orcid":false,"given":"Javier","family":"Vicente","sequence":"first","affiliation":[{"name":"Electronics and Computing Department, Mondragon Unibertsitatea, 20500 Mondragon, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9887-0925","authenticated-orcid":false,"given":"P.","family":"Costa","sequence":"additional","affiliation":[{"name":"Center of Physics, University of Minho, 4710-057 Braga, Portugal"},{"name":"Institute for Polymers and Composites (IPC), University of Minho, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6791-7620","authenticated-orcid":false,"given":"S.","family":"Lanceros-Mendez","sequence":"additional","affiliation":[{"name":"BCMaterials, Basque Center for Materials, Applications and Nanostructures, UPV\/EHU Science Park, 48940 Leioa, Spain"},{"name":"IKERBASQUE, Basque Foundation for Science, 48013 Bilbao, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0066-3587","authenticated-orcid":false,"given":"Jose Manuel","family":"Abete","sequence":"additional","affiliation":[{"name":"Applied Mechanics Department, Mondragon Unibertsitatea, 20500 Mondragon, Spain"}]},{"given":"Aitzol","family":"Iturrospe","sequence":"additional","affiliation":[{"name":"Electronics and Computing Department, Mondragon Unibertsitatea, 20500 Mondragon, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1026","DOI":"10.1038\/nnano.2016.262","article-title":"Polymer matrix nanocomposites for automotive structural components","volume":"11","author":"Naskar","year":"2016","journal-title":"Nat.
