The organic-inorganic hybrid anion exchange membranes were prepared from quaternary triethylamonium functionalized poly(2,6-dimethyl-1,4-phenyleneoxide) (QPPO) and 3-glycidoxypropylthrimethoxysilane (GOPS) with different ratios. The obtained membranes are termed as QPPO(x)-G(y), where x and y are the mole ratios of triethylamine and the siloxane GOPS to the bromomethyl groups of the polymer, respectively. The resultant hybrid membranes are thermally stable up to 200 degrees C and exhibit a tensile stress of around 10 MPa. The incorporated GOPS endows the hybrid membranes with increased water uptake and conductivity due to the more hydroxyl groups containing in the hydrolytic networks of GOPS in the membranes. A conductivity of 46.0 mS cm(-1) is achieved by the QPPO(0.4)-G(0.55) membrane in water at 80 degrees C, which is about 20 mS cm(-1) higher than the conductivity of the pristine QPPO(0.4 )membrane. In addition, the QPPO(0.4)-G(y) hybrid membranes possess enhanced alkaline tolerance toward the attack of hydroxide ions. After soaked in 1 M KOH at 60 degrees C for 480 h, the hybrid membranes retained more than 16-22% of the initial conductivity compared to the pristine QPPO(0.4) membrane.
