复合双极膜又称复合双层膜（BPM），通常由阳离子交换层、阴离子交换层和夹在两者之间的机械增强体组成。阳离子交换层（CEL）是由机械增强体一侧使用阳离子交换分散体制成的，阴离子交换层（AEL）是通过在机械增强体的对侧利用阴离子交换分散体而制成，基于聚四氟乙烯的微孔增强层集成到膜的结构中，以提供增强的机械性能和减少膨胀并增加CEL和AEL之间的界面面积，双极膜具有机械强度高、离子选择性强和化学稳定性高的特点。

科学材料站可以提供Xion BPM-Dyneon-725-Dappion (30, 75μm) 双极膜不同厚度尺寸系列，其中厚度有30和75μm，尺寸有5x5cm, 10x10cm及15x15cm。更多型号将在厂家更新后提供。

科学材料站（SCI Materials Hub）可以根据用户需求设计和制造各种配置的双极膜，公司与诸如杜邦公司、科慕公司、3M公司、索尔维公司等多家知名的离子交换树脂供应商合作，可以获得Nafion、Aquivion、Dyneon、Pention、Durion等业内多种阳离子交换离聚物（CEI）和阴离子交换离聚物（AEI）以供选择，设计出多种组合的复合双极膜（BPM）。

双极膜通常用于各种电化学应用中的水裂解反应。在AEL和CEL的界面上，当超过大约0.8V的电位差时，水分子会分解成氢离子和氢氧根离子。CEL必须朝向阴极，AEL必须朝向阳极，并且操作模式必须反向偏压，以促进水离解反应。在反向偏压模式下，电子从阳极侧转移到阴极侧。由于AEL和CEL之间存在亲水结构域，水分子会自然地扩散到AEL和CEL之间的中间层中，水的分裂反应会产生氢离子和氢氧根离子。氢离子将从CEL层扩散到阴极室。另一方面，氢氧根离子会从AEL层扩散出去并迁移到阳极室中。与传统的水电解不同，电催化作用下的水分解无反应气体产生。因此，一摩尔的氢氧根离子和氢离子可以在大约22 Wh的能量值下实现（电解：大约55 Wh/Mol），如下图所示：

复合双极膜的反向偏压和正向偏压操作模式：

下图a显示了在反向偏压模式下复合双极膜的示意图，在该模式下，界面层首先耗尽离子，然后水分解成氢离子和氢氧根离子。图b描述了复合双极膜在正向偏压模式下的操作，其中氢离子和氢氧根离子通过各自的层被输送到双极膜中，在双极结处形成水（也称为双极界面或界面层）。AEL代表阴离子交换层，CEL代表阳离子交换层，IL代表界面层。

复合双极膜和离子交换膜的各种用途的科学文献推荐：

Jaroszek和Dydo撰写的题为“Ion-exchange membranes in chemical synthesis - a review”一文是很好的来源，可以帮助我们正确地使用复合双极膜和其他离子交换膜，通过电渗析、2室膜电解、3室电渗析进行各种化学合成反应，四室电渗析复分解、双极膜电渗析、电去离子、离子置换电渗析、唐南透析等。

BPM-Nafion-Durion-G2复合双极膜由我公司研制的Durion-G2基阴离子交换层（AEL）和科慕公司研制的Nafion-1000EW基阳离子交换层（CEL）组成,这种复合双极膜的厚度有30um和75um两种规格，尺寸有：5cmX5cm、10cmX10cm、15cmX15cm三种规格。

BPM-Nafion-Durion-G2复合膜的参数：

√ 高水解效率（在25℃，100 mA/cm2时，0.5 M NaCl中＞98%）

√ 低水解电压（在25℃，100 mA/cm2时，0.5 M NaCl中＜1.2V）

√ 低厚度下的优良机械性能

Xion BPM-Nafion-1000-Durion-G2 composite bipolar membranes consist of Durion G2 based anion exchange layer (AEL) and Nafion 1000 based cation exchange layer (CEL). This composite bipolar membrane has a thickness of 30 micrometers. Durion G2 anion exchange resin is based on polyphenylene backbone with a hybridized imidazole side chain which functions as the functional groups for anion transfer within the AEL. Nafion 1000 resin is based on the perfluorosulfonic acid composition with long side chain and it has sulfonic acid as its functional groups for cation transfer within the CEL.

A composite bipolar membrane is usually comprised of a mechanical reinforcement that is sandwiched between a cation exchange layer and an anion exchange layer. Cation exchange layer (CEL) is formed by the cation exchange dispersion on one side of the mechanical reinforcement. An anion exchange layer (AEL), on the other hand, is formed from the use of an anion exchange dispersion on the opposite side of the mechanical reinforcement. A composite bipolar membrane can also be called as composite bilayer membrane. The microporous e-PTFE based reinforcement layer is integrated into the structure of the bipolar membrane to provide enhanced mechanical properties, reduced swelling, and increasing the interface area between the CEL and AEL.

Bipolar membranes are usually used for water splitting reactions in various electrochemical applications. At the interface of AEL and CEL, water molecules are dissociated into OH- and H+ ions when exceeding a potential difference of approximately 0.8 V. The CEL must be directed towards the cathode, the AEL must be directed towards the anode, and the mode of operation has to be reverse biased in order to promote the water dissociation reaction. Under the reverse biased mode, the electrons would be transferred from anode side to cathode side. Water molecules would naturally diffuse into the intermediate layer between AEL and CEL due to presence of hydrophilic domains within those respective layers and generation of H+ and OH- ions would occur as a result of water splitting reaction. H+ ions will diffuse out from the CEL layer and migrate into the cathode chamber. OH- ions, on the other hand, would diffuse out from the AEL layer and migrate into the anode chamber. The electro-catalytically forced water dissociation produces – in contrast to the classical electrolysis of water – no reaction gases. Therefore, one Mol of OH- and H+ – ions can be achieved at an energy value of approximately 22 Wh (Electrolysis: approximately 55 Wh per Mol).

These are developmental products that are currently being offered to researchers for their various electrochemical applications and hence, the amount of experimental data is is scarce and our team hopes that customers purchasing these products would provide some feedback in order to further improve their electrochemical performances.

Reverse Bias and Forward Bias Operation Modes with Composite Bipolar Membranes:

Figure (a) provides the schematic representation of the composite bipolar membrane under reverse bias mode, where first the junction is depleted of ions and then water dissociates into H+ and OH- ions. Figure (b) describes the operation of a composite bipolar membrane under forward bias mode, where H+ and OH- ions are transported into the bipoplar membrane through their respective layers and water is formed at the bipolar junction (also called as bipolar interface or interface layer). AEL stands for anion exchanger layer, CEL stands for cation exchange layer, IL stands for interface layer.

Scientific Literature for Various Use of Composite Bipolar and Ion Exchange Membranes:

The article by Parnamae et. al entitled "Bipolar membranes: A review on principles, latest developments, and applications" is considered to be an excellent source that describes the operating principle of bipolar membranes, provides a very through analysis of the recent progress in the area of bipolar membranes and use of such membranes in various applications.

The article by Jaroszek and Dydo entitled " Ion-exchange membranes in chemical synthesis - a review" is considered to be an excellent source for how to properly use a composite bipolar and other ion exchange membranes for various chemical synthesis reactions via electrodialysis, 2-chamber membrane electrolysis, 3-chamber electro-electrodialysis, 4-chamber electrodialysis metathesis, electrodialysis with bipolar membrane, electrodeionization, ion substitution electrodialysis, Donnan dialysis, etc.
