摘要:

为了提高阴离子交换膜的离子传导率,本文以降冰片烯二酸酐为原材料,单体中引入两个官能团提高单位体积内离子交换容量制备了阴离子交换膜。通过Materials Studio(MS)软件计算反应能垒,分析判断双季铵化单体形成与否的可行性。模拟计算与实验结果表明:分子结构设计合理,实验方法可行。当单体与降冰片烯比例为1:2.5时,最高离子传导率σ达到65.21 mS·cm-1,离子交换容量为2.56 mequiv·g-1,吸水率为22.6%。

Abstract:

In order to improve the anion-exchange membrane ion conductivity, an anion exchange membrane was prepared which the norbornene anhydride as a raw material monomer, two functional groups were introduced on the monomer for increasing the ion exchange capacity per unit volume.Materials Studio (MS) software was used to calculate energy barrier, analyze the feasibility of forming a judgment diquaternary monomers or not.Simulation and experimental results show that the molecular structure design and the experimental method is feasible.When the monomer and norbornene ratio of 1:2.5, the highest ionic conductivity σ reached 65.21 mS·cm-1, an ion exchange capacity of 2.56 mequiv·g-1, the water absorption was 22.6%.

Key words: anion exchange membrane, norbornene, ring-opening metathesis polymerization, conductivity, simulation
