但其采用苯-烷基-苯结构特点的单体难以直接购买，需要进一步合成，增加了制备难度

Benefits of technology

[0064] This invention introduces an appropriate proportion of flexible segments into a polyphenylene-containing anion exchange resin, which reduces the packing density of the polymer chains and increases the inter-chain spacing. The increased spacing provides more transport channels for ions, reducing mass transfer resistance. At the same time, it can regulate the hydrophilicity of the polymer and reduce the interfacial resistance of the electrolyzer. When applied to an electrolyzer, the polyphenylene-containing anion exchange membrane has good toughness and excellent electrochemical performance, with a conductivity as high as 160 mS/cm at 80 °C.
