1概况在制取横基阳离子交换股时全氟化碳酸氟共聚物的水解一般在90℃的6NNaOH中进行6h。磺酰氟共聚物的另一种标准化学改性是用无水脂族胺──乙烯二胺、二乙烯三胺等进行腔化。从改进膜对输送离子和中性分子的输送和选择性能的观点来看，最好的方法是在四氢－1，4－氧氮杂环己 1 General The hydrolysis of the perfluorocarbonated fluorocarbon copolymer during preparation of the cross-linked cation exchange strands is generally carried out in 6N NaOH at 90 ° C for 6 h. Another standard chemical modification of sulfonyl fluoride copolymers is the use of anhydrous aliphatic amine ─ ─ ethylenediamine, diethylenetriamine and other cavity. From the viewpoint of improving the transport and selectivity of the membrane to the transport of ions and neutral molecules, the best method is to treat the tetrahydro-1,4-oxazaborole
