What a swell for hydroxides: The typical trade-off between swelling control and ion conductivity in ion-conducting polymer membranes is overcome by enhancement of van der Waals interactions among polymer chains. Using a quaternary phosphonium-functionalized polymer, the simple combination of high electron density of the polymer and large dipole moment of the functional group leads to low membrane swelling, high hydroxide conductivity, and excellent hydroxide exchange membrane fuel cell performance.
在离子传导聚合物膜中，通过增强聚合物链之间的范德华相互作用，可以克服溶胀控制和离子传导之间的典型权衡。使用季铵盐功能化聚合物，聚合物的高电子密度和官能团的大偶极矩的简单组合导致低膜溶胀、高氢氧化物电导率和优异的氢氧化物交换膜燃料电池性能。
