The electrical conductivity of a family of glassy protonic electrolytes defined by the general formula (P2O5)x(SiO2)y, where x\/y is 3\/7 are studied by Alternating Current electrochemical impedance spectroscopy (AC EIS) method. The reference glass was doped with polymeric additives\u2014poly(ethylene oxide) (PEO) and poly(vinyl alcohol) (PVA), and additionally with a titanium-oxide-based filler. Special attention was paid to determination of the transport properties of the materials thus modified in relation to the charge transfer phenomena occurring within them. The electrical conductivities of the \u2018dry\u2019 material ranged from 10\u22124 to 10\u22129 S\/cm, whereas for \u2018wet\u2019 samples the values were ~10\u22123 S\/cm. The additives also modified the pore space of the samples. The pore distribution and specific surface of the modified glassy systems exhibited variation with changes in electrolyte chemical composition. The mechanical properties of the samples were also examined. The Young\u2019s modulus and Poisson\u2019s ratio were determined by the continuous wave technique (CWT). Based on analysis of the dispersion of the dielectric losses, it was found that the composite samples exhibit mixed-type proton mobility with contributions related to both the bulk of the material and the surface of the pore space.<\/jats:p>","DOI":"10.3390\/ma13133004","type":"journal-article","created":{"date-parts":[[2020,7,6]],"date-time":"2020-07-06T11:07:42Z","timestamp":1594033662000},"page":"3004","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Ionic Transport Properties of P2O5-SiO2 Glassy Protonic Composites Doped with Polymer and Inorganic Titanium-based Fillers"],"prefix":"10.3390","volume":"13","author":[{"given":"Maciej","family":"Siekierski","sequence":"first","affiliation":[{"name":"Faculty of Chemistry, Warsaw University of Technology, Noakowskiego 3 Str., 00-640 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0984-9855","authenticated-orcid":false,"given":"Maja","family":"Mroczkowska-Szersze\u0144","sequence":"additional","affiliation":[{"name":"Oil and Gas Institute-National Research Institute, Lubicz 25a Str., 31-503 Cracow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafa\u0142","family":"Letmanowski","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Warsaw University of Technology, Noakowskiego 3 Str., 00-640 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dariusz","family":"Zabost","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Warsaw University of Technology, Noakowskiego 3 Str., 00-640 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Micha\u0142","family":"Piszcz","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Warsaw University of Technology, Noakowskiego 3 Str., 00-640 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lidia","family":"Dudek","sequence":"additional","affiliation":[{"name":"Oil and Gas Institute-National Research Institute, Lubicz 25a Str., 31-503 Cracow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3086-469X","authenticated-orcid":false,"given":"Micha\u0142 M.","family":"Struzik","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Warsaw University of Technology, 75 Koszykowa Str., 00-662 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4653-0958","authenticated-orcid":false,"given":"Magdalena","family":"Winkowska-Struzik","sequence":"additional","affiliation":[{"name":"\u0141ukasiewicz Research Network-Institute of Electronic Materials Technology, 133 W\u00f3lczy\u0144ska Str., 01-919 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renata","family":"Cicha-Szot","sequence":"additional","affiliation":[{"name":"Oil and Gas Institute-National Research Institute, Lubicz 25a Str., 31-503 Cracow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magdalena","family":"Dudek","sequence":"additional","affiliation":[{"name":"Faculty of Energy and Fuels, AGH University of Science and Technology, Av.
