| 中文摘要 | a series of comb-type amphiphilic copolymers (pes-g-peo) with a stiff poly(aryl ether sulfone) backbone and flexible peo side chains was synthesized via a "grafting onto" technique. by controlling the monomer feed ratios, high molecular weight copolymers with a range of peo side chain content were prepared and used to form tough and flexible membranes. the pes-g-peo membranes displayed high thermal stability (t(d) > 230 degrees c) and good mechanical properties. the water contact angles of the pes-g-peo membranes ranged from 60.5 degrees to 66.7 degrees, 20 degrees lower than those of poly(aryl ether sulfone) membranes (82-86 degrees), indicating that the peo side chains improved the hydrophilicity of the membranes. wide-angle x-ray diffraction results indicated that the pes-g-peo membranes possessed an amorphous structure, that is, crystallization of the peo side chains did not occur. the li-ion conductivity reached 2.26 x 10(-4) s/cm at room temperature, much higher than that of the pure peo-based system (10(-6) s/cm), due to the presence of the amorphous peo side chains between the pes backbones, which provided an effective li-ion transport pathway.
