Poly(butylvinylimidazolium)(b-VIB) is copolymerized with para-methyl styrene (p-MS) by the radical polymerization formed block copolymers b-VIB/p-MS, which is crosslinked with poly(diphenylether bibenzimidazole) (DPEBI) providing the desired materials b-VIB/p-MS/DPEBI. Structures are characterized via H1NMR, FTIR spectra and elemental analysis. The b-VIB blocks offer the anion conduction function while DPEBI moieties contribute to enhancing other properties. The prepared membranes display chloride conductivity as high as 19.5 mS/cm at 25 °C and 69.2 mS/cm at 100 °C-higher than that of the commercial membrane tokuyuama A201-. Their hydroxide conductivity reaches 35.7 Scm?1 at 25 °C and 73.1 Scm?1 at 100 °C. The membranes showed a linear Arrhenius behavior in the anion conduction, low activation energies and distinguished nanophase separation of hydrophilic/hydrophobic regions by the transmission electron microscopy (TEM) studies. Thermal investigations using TGA and DSC confirm that the membranes are stable up to 250 °C. Particularly, drastically alkaline stability due to no decrease in the hydroxide conductivity after 168 h of treatment with 2M KOH. © 2017 Elsevier B.V.14aANION CONDUCTIVITY14aANION EXCHANGE MEMBRANE14aFUEL CELL12aOuadah A.12aXu H.12aLuo T.12aGao S.12aWang X.12aFang Z.12aJing C.12aZhu C.40uhttps://drive.google.com/file/d/1ms-goIgdSYAymDAttsEiUc-z_icUpiLh/view?usp=drive_linkzPara ver el documento ingresa a Google con tu cuenta @cicy.edu.mx 2LoccREF1250602s9999 xx |||||s2 |||| ||und|d c31420d31420 00102Loc40708F1aCICYbCICYcREd2025-06-25l0oB-21422r2025-06-25 16:43:54w2025-06-25yREF1
