High-temperature polymer electrolyte membranes based on poly(2,5-benzimidazole) (ABPBI) and POSS incorporated ionic liquid Fan Zhang Xujin Bao Qingting Liu Mengyao Huang 2134/22408 https://repository.lboro.ac.uk/articles/journal_contribution/High-temperature_polymer_electrolyte_membranes_based_on_poly_2_5-benzimidazole_ABPBI_and_POSS_incorporated_ionic_liquid/9235439 This paper reported a method to modify polyhedral oligomeric silsesquioxane (POSS) particle into POSS ionic liquid (POSS-IL) and its incorporation into ABPBI/H3PO4 system to enhance the proton conductivities and mechanical properties of the membranes simultaneously. It was found that good dispersion of POSS-IL in the polymer matrix increased the tensile strength and Young’s modulus of the membranes. For membranes with the same H3PO4 content, the incorporation of POSS-IL increased the conductivities of the membranes by about two orders of magnitude. The highest conductivity was achieved by ABPBI/10 wt% POSS-IL composite membrane, which was 7.6×10-2 S/cm at 200 °C. 2016-09-12 14:11:02 POSS High-temperature PEM Hydrogen fuel cell Materials Engineering not elsewhere classified
