摘要

为制备出同时具备高电导率和高稳定性的阴离子交换膜（AEM），以1

6-二溴己烷为交联剂，采用浇铸法制备了不同交联度的交联型聚(联苯-哌啶)AEM（PBP-Pip-

%膜，

代表交联度，取值分别为5、10和15）。分别采用

H NMR和AFM对PBP-Pip-

%膜的结构和形貌等进行了表征，并以未交联的聚(联苯-哌啶)AEM（PBP-Pip膜）作为对照组，研究了PBP-Pip-

%膜的性能。结果表明，PBP-Pip-15%膜具有更好的微相分离结构，其电导率（99.14 mS/cm）较PBP-Pip膜的电导率（49.89 mS/cm）明显提高。PBP-Pip-15%膜表现出较好的碱稳定性，在1 mol/L KOH溶液中于80 ℃浸泡300 h后，其电导率为37.50 mS/cm，电导率保留率为79.73%。在设定条件（温度为80 ℃、1 mol/L KOH溶液中和小室电压为2.0 V）下，PBP-Pip-15%膜的电流密度为0.5 A/cm

，并且在100 h内稳定性未发生明显改变。

Abstract

In order to prepare anion exchange membrane (AEM) with high conductivity and high stability

6-dibromohexane was used as crosslinking

agent

and cross-linked poly (biphenyl-piperidine) AEM (PBP-Pip-

% membrane

represents crosslinking degree and the values of

are 5

10 and 15

respectively) with different crosslinking degrees were prepared by casting method. The structures and morphologies of PBP-Pip-

% membranes were characterized by

H NMR and AFM

respectively

and the properties of PBP-Pip-

% membranes were studied by using uncross-linked poly (biphenyl-piperidine) AEM (PBP-Pip membrane) as the control group. The results show that PBP-Pip-15% membrane has better microphase separation structure

and its conductivity (99.14 mS/cm) is significantly higher than that of the PBP-Pip membrane (49.89 mS/cm). PBP-Pip-15% membrane shows good alkali stability

and after soaking in 1 mol/L KOH solution at 80 ℃ for 300 h

the conductivity of PBP-Pip-15% membrane is 37.50 mS/cm and the conductivity retention rate is 79.73%. Under the set up conditions (temperature of 80 ℃

1 mol/L KOH solution and cell voltage of 2.0 V)

the current density of PBP-Pip-15% membrane is 0.5 A/cm

and the stability of PBP-Pip-15% membrane does not change significantly within 100 h.
