科学材料站（SCI Materials Hub）可以提供各种分散液和膜溶液产品，用于燃料电池、电解槽、液流电池和其他电化学设备。分散液和膜溶液可用于制造不同厚度的自支撑和机械增强膜。气体扩散电极也可以利用这些分散液和膜溶液制作。

Pention系列分散液（也称为离聚体溶液）是高导电性和稳定的液体溶液，因此可用于包含阴离子交换膜（AEM）的电极层中。分散液结构为聚降冰片烯主链，以官能化和非官能化两种形式出售。官能化聚合物用季铵盐基团官能化，作为用于电极层的分散液出售（例如制备用于催化气体扩散层或气体扩散电极GDE等的催化剂油墨或浆液）。官能化聚合物不溶于传统溶剂体系，因此对于膜浇铸，非官能化聚合物溶解在有机溶液中，并且必须在膜制作步骤之后进行官能化。无功能聚合物以溶液形式出售。产品名称中的“D”代表分散液，“S”代表膜溶液。分散液是一种离子导电材料，可以按收到的形式使用。另一方面，解决方案目前正以非官能化的形式提供，用这些解决方案制造的产品需要官能化，以使其具有离子导电性。

下图为季铵改性聚降冰片烯聚合物的化学结构：

目前，科学材料站（SCI Materials Hub）的Pention-D型分散液有D18、D35、D72三个系列。

Pention分散液的亲水性顺序为：D72系列（亲水性最强）＞D35系列＞D18系列（亲水性最低）。小于D72系列疏水分散液（至少D72系列）是疏水的。如果保持水化或保持水对预期用途很重要，则应使用最亲水的分散液。如果去除副产品水对预期用途很重要，则应使用中间或最疏水的分散液。

Pention-D18-5wt%是一种季铵盐官能化分散液，聚合物浓度为5wt%。该分散液属于D18系列。其IEC（meq/g）为1.05-1.15，该分散液产品很适合电极制造，例如催化气体扩散层和其他类似产品/组件。

Pention-D35-5wt%是一种季铵盐官能化分散液，聚合物浓度为5wt%。该分散液属于D35系列。其IEC（meq/g）为1.95-2.05，该分散液产品很适合电极制造，例如催化气体扩散层和其他类似产品/组件。

Pention-D72-5wt%是一种季铵盐官能化分散液，聚合物浓度为5wt%。该分散液属于D72系列。其IEC（meq/g）为3.45-3.55，该分散液产品很适合电极制造，例如催化气体扩散层和其他类似产品/组件。

Pention系列分散液（也称为分散液）产品可用于各种电化学应用，包括燃料电池、电解槽、传感器、液流电池和其他各种电化学应用。用Pention树脂制成的膜显示了AEM燃料电池的最高记录性能，峰值功率密度为3.4 W/cm2（美国可再生能源实验室、南卡罗来纳大学和乔治亚理工学院联合开展的研究，研究原文见文末或本站下载中心）。所述的电化学性能数据仅供参考，并取决于MEA、CCM或GDE制造方法、使用的膜厚度、测试硬件设计和测试硬件中使用的组件以及操作参数（温度、压力、反应物流速等），这些值可能会或可能不会达到。

Pention系列分散液（也称离聚体溶液）的主要优点：

√ 非常高的导电性

√ 化学稳定性高

√ 亲水性或疏水性取决于所选系列的分散产品

请注意，Pention系列分散剂为有机溶剂，如果长时间接触瓶盖，可能会破坏瓶子的密封。我们建议在收到货物后立即将瓶子直立存放，以减少意外泄漏的可能性。

1. 简介

Pention dispersions (also known as ionomers) are highly conductive and stable liquid solutions, and therefore useful for incorporation into electrode layers involving anion exchange membranes (AEM).

2. 应用

Pention dispersion products can be used in various electrochemical applications including fuel cells, electrolyzers, sensors, and flow batteries and other electrochemical applications/technologies. Membranes with Pention resin have demonstrated the highest recorded AEM fuel cell performance with a peak power density of 3.4 W/cm2 (jointly conducted study between NREL, University of South Carolina, and Georgia Institute of Technology).

3. 特性

The ionomer structure contains a poly(norbornene) backbone and is sold in either functionalized and non-functionalized forms. The functionalized polymer is sold as a dispersion for use in electrode layers and is functionalized with a quaternary ammonium group.

The functionalized polymer is not soluble in conventional solvent systems, so for membrane casting the unfunctionalized polymer is dissolved in solution and must be functionalized after membrane manufacture.

The unfunctionalized polymer is sold in the solution form. "D" in the product name stands for dispersion and "S" in the product name stands for solution. Dispersions are ionically conducting materials and ready to be used in the as received form. Solutions, on the other hand, are currently being supplied in the unfunctionalized form and the products made with the solutions needs to be functionalized in order to make them ionically conductive.

4. 理化性质

Chemical composition of the quaternary ammonium modified poly(norbornene) polymer is provided below.

Pention-D18-5wt% is a quaternary ammonium functionalized dispersion with 5wt% polymer concentration in an organic solvent. This dispersion belongs to D18 series. This product has an IEC (meq/g) of 1.05 to 1.15. Dispersion products are highly suitable for electrode manufacturing such as catalyzed gas diffusion layers and other similar products/components.

5. 亲疏水性

Hydrophilic order of Pention dispersions as follows: D72 series (the most hydrophilic) >> D35 series >> D18 series (the least hydrophilic).

Hydrophobic order of Pention dispersions as follows: D72 series (the least hydrophobic) << D35 series << D18 series (the most hydrophobic).

If maintaining the hydration or keeping the water is important for the intended application, then the most hydrophilic dispersion should be used. If removal of the by-product water is important for the intended application, then the intermediate or most hydrophobic dispersion should be used.

Pention dispersion (also known as ionomers) products can be used in various electrochemical applications including fuel cells, electrolyzers, sensors, and flow batteries and other electrochemical applications/technologies. Membranes with Pention resin have demonstrated the highest recorded AEM fuel cell performance with a peak power density of 3.4 W/cm2 (jointly conducted study between NREL, University of South Carolina, and Georgia Institute of Technology). The stated electrochemical performance data is for reference only and depending on the MEA, CCM or GDE manufacturing method, used membrane thickness, testing hardware design and components used in the test hardware, and operational parameters (temperature, pressure, reactant flow rates, etc.), those values may or may not be attained.

- Very high conductivity
- Great chemical stability
- Hydrophilic or hydrophobic natured depending on the selected series of the dispersion products

Pention-D18-5wt%, a quaternary ammonium functionalized dispersion with 5wt% polymer concentration in an organic solvent, was obtained from SCI Materials Hub.

Pention dispersions are considered hazardous items under DOT and IATA regulation. 125 mL and 250 mL dispersions will incur a hazardous fee to accommodate the regulations based on the final shipping location (which is included in the pricing listed on the Fuel Cell Store product pages).

Please note that Pention dispersions contain solvents that may compromise the seals of the bottles if the solvents are left in direct contact with the lids for long periods of time. We recommend always storing the bottles in an upright orientation as soon as the shipment is received to lessen the likelihood of inadvertent leakage.

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