The TGA, DSC and FTIR characterization results for the so obtained nanoporous membranes reveal the chemical modification of PBI upon irradiation along the track walls. A clear conduction outperforming is shown by phosphoric acid doped track-etched PBI in comparison with dense PBI counterparts. This behavior could be explained by the effective contribution of additional pathways for proton transport involving shorter benzimidazole fragments, cross-linked PBI nanodomains and free amphoteric phosphoric acid molecules settled on the pore walls. info:eu-repo/grantAgreement/EC/FP7/209481/EU/NANOSTRUCTURED ELECTROLYTE MEMBRANES BASED ON POLYMER-IONIC LIQUIDS-ZEOLITE COMPOSITES FOR HIGH TEMPERATURE PEM FUEL CELL/ZEOCELL info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.056 2014 POLYMER SCIENCE 7 / 82 = 0.085 2014 Q1 T1 ENGINEERING, CHEMICAL 7 / 135 = 0.052 2014 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sgroi, Mauro Pullini, Daniele Ferain, Etienne (orcid)0000-0001-9897-6527 Pina Iritia, Maria Pilar Universidad de Zaragoza 5005 555 Universidad de Zaragoza Dpto.
