A Hierarchically Porous Carbazole-Containing Polymer from [p-(4-N-carbazole)-C6H4SiO1.5]8 to Load Imidazole for Efficient Proton Conductivity over a Wide Temperature Range

摘要

The practical application of vehicle fuel cell technology requires solid electrolytes possess not only high proton conductivity, but also stable proton transport channel with a wide operating temperature window. In addition, hierarchically porous materi- als play a key role in mass transport, such as the concentration and mobility of proton carries. Herein, we present a novel strategy to target this goal. A new hierarchically porous carbazole-containing polymer (ECUT-PP) was reported via mechanochemical grinding of [p-(4-N-carbazole)C6H4SiO1.5]8 and anhydrous FeCl3 catalyst at room temperature.
