预处理方案:

Xion-Durion复合阴离子膜以溴化物或氯化物形式运输。

1.当用于标准碱性燃料电池/电解池时,应通过用0.5-1.0 M NaOH或KOH溶液处理将膜转化为OH-形式:将膜样品置于0.5–1.0 M NaOH或KOH的水溶液中,在20℃–30℃下放置24小时。用去离子水(pH?7)冲洗后,膜即可使用。请使用密闭容器以避免CO2污染(碳酸盐的形成可能会影响电导率)。OH-形式的膜必须在潮湿/加湿且不含CO2的条件下保存,避免OH-形式的膜变干。在干燥条件下的长期储存应优选以碳酸盐,Cl-或Br-形式进行。


2.当用于其他电化学(电渗析,脱盐,电渗析,反向电渗析,酸回收,盐分离等)和非电化学应用时,应将膜转换为与预期应用相关的阴离子形式。例如,如果应用程序要求将Cl-阴离子通过膜转移,则该阴离子交换膜需要转化为Cl-形式。为了将该膜转化为Cl-形式,需要将其浸入1-2 M NaCl或KCl盐溶液(溶于去离子水中)24-72小时,然后用去离子水冲洗以除去膜表面多余的盐。或者,如果预期的应用需要转移硫酸根阴离子,则该阴离子交换膜需要先预处理成硫酸根形式,在室温下将膜完全浸入盐溶液中24-72小时后,Na2SO4或K2SO4的中性盐溶液通常足以使膜完全转化为硫酸盐形式。

The Xion AEM-Durion-G2 membrane is a composite anion exchange membrane (AEM) that uses the Durion Gen2 resin as the polymer backbone with a hybridized imidazole side chain as its functional group and has an ion exchange capacity of 2.1 - 2.5 mequiv/g. Durion Gen2 membranes offer excellent mechanical strength and stability to a wide variety of chemistries. SCI Materiasl Hub currently provides Durion Gen2 anion exchange membrane sheets in 5, 10, 20, and 30μm thicknesses and 5x5cm, 10x10cm and 15x15cm sizes. Image on the right side shows the chemical composition of the anion exchange resin used to manufacture Xion Composite Durion Gen 2 membranes.


The Xion AEM-Durion-G2 can be used in fuel cells, electrolyzers, electrodialysis, redox flow batteries, electrochemical compressors, and a wide variety of other devices.


XION Composite Durion Gen2 AEMs are ultra-thin, ultra-strong, provide ultra-high performance for various alkaline chemistry based applications. The ionomer structure contains a polyphenylene backbone with a hybridized imidazole side chain for its functional groups. A reinforcement layer is integrated into the structure of the membrane to provide enhanced mechanical properties and this is composed of microporous ePTFE (also known as expanded PTFE). The enhanced mechanical properties as free-standing membranes, providing higher ionic conductance without sacrificing strength.


Benefits of Xion Composite Durion Gen2 AEMs:

High anionic conductivity
Great chemical stability at low and high temperatures
Ultra-thin membranes with excellent mechanical strength


Pre-Treatment and Conditioning:

The membrane is delivered in dry form with the counter anion being either in bromide or chloride. Depending on application and cell design, assembling is possible in dry form (without pretreatment) or wet form.


For standard alkaline fuel cell / electrolysis applications, the membrane should be converted into OH-form by treating it with 0.5 – 1.0 M NaOH or KOH solution: Put the membrane sample in an aqueous solution of 0.5 – 1.0 M NaOH or KOH for at least 24 h at 20°C – 30°C. After rinsing with demineralised water (pH ~ 7) the membrane is ready to use. Use closed container to avoid CO2 contamination (carbonate formation that may affect conductivity). The membrane in OH-form must be stored under wet / humidified and CO2-free conditions, avoid drying out of the membrane in OH-form. Long-term storage in dry conditions should be preferably done in carbonate, Cl- or Br-form.

For electrochemical CO2 reduction applications, the anion exchange membrane should be converted to the carbonate or bicarbonate form by treating the membrane initially with 0.1 to 0.5 M KOH or NaOH solution and then with 0.1 to 0.5 M water soluble carbonate or bicarbonate salt solutions (such as potassium carbonate or potassium bicarbonate that is dissolved in de-ionized water or distilled water). Fully submerging the anion exchange membrane into KOH or NaOH solution for 6 to 12 hours and then to the desired carbonate or bicarbonate salt solution for a period of 48-72 hours would be sufficient to fully convert the membrane into either carbonate or bicarbonate form. After rinsing the membrane (which is in the carbonate form) with deionized water or distilled water, it can be assembled inside the electrochemical setup for electrochemical CO2 reduction experiments. While the submersion of the membrane into the KOH or NaOH can be skipped, for such situations, a longer submersion time may be required in order to fully convert the membrane to carbonate or bicarbonate form. Initial conversion to OH- form significantly improves the carbonate ion exchange process due to expanded pore sizes.

For other electrochemical (electrodialysis, desalination, electro-electrodialysis, reverse electrodialysis, acid recovery, salt splitting, etc.) and non-electrochemical applications, the membrane should be converted into the anionic form that is relevant for the intended application. For example, if the application is requiring the Cl- anions to be transferred through the membrane, then this anion exchange membrane needs to be converted into the Cl- form. In order to convert this membrane into Cl- form, it needs to be submerged into a 1-2 M salt solution of NaCl or KCl (dissolved in deionized water) for a period of 24-72 hours and then rinsed with deionized water to remove the excess salt from the membrane surface. Or if the intended application is requiring to transfer sulfate anions, then this anion exchange membrane needs to be converted into the sulfate form prior to its assembly into the cell. A neutral salt solution of Na2SO4 or K2SO4 would usually be sufficient to achieve the full conversion of membrane into the sulfate form after fully submerging the membrane into the salt solution for 24-72 hours at room temperature.

Scientific Literature for Various Use of Durion Gen2 AEMs and Dispersion Products:

The article by Chen and Lee entitled "Anion Exchange Polyelectrolytes for Membranes and Ionomers" is an excellent review that summarizes the development of various anion exchange polyelectrolytes (including polyphenylene based ones), importance of functional side's chemical structure and how it is connected to the backbone, importance of polymer backbone and how it affects the overall durability ionomer and membranes.


The article by Hugar et al. entitled "Imidazolium Cations with Exceptional Alkaline Stability: A Systematic Study of Structure-Stability Relationships" investigates the effects different substituents on the alkaline stability of imidazolium groups in 1M, 2M, and 5M KOH at 80 °C and their results indicate that polyphenylene-type anion exchange dispersions and membranes possess outstanding alkaline stability (ex-situ durability) and high anion conductivity.


A typical lead time of 2-3 weeks is to be expected.
