改性聚砜交联离子交换膜的合成

SYNTHESIS OF CROSSLINKED POLY(SULFONE) ION EXCHANGE MEMBRANE

聚合物离子交换膜是聚合物电解质燃料电池的重要组成部分，同时也广泛地应用于电渗析、电解等电化学过程中，其性能优劣直接决定了过程的效果［１～３］。九十年代初期，随着Ｄｕｐｏｎｔ的Ｎａｆｉｏｎ膜在聚合物电解质燃料电池中的成功应用，已使燃料电池技术取得重大进...

The produce process and characteristics of Cross linked PSU membrane were studied. The metalation is introduced in the PSU to make the sulfinated and sulfonated PSU, followed by the partial oxidation and cross linking, the ion exchanged PSU membrane is prepared. The results on swelling and resistance, permselectivity and thermal stability were obtained which show that the cross linked PSU membranes have small swelling, lower resistance, good permselectivity and thermal stabiity.
