科学材料站(SCI Materials Hub)提供各种分散液和膜溶液产品,可用于燃料电池、电解槽、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。催化气体扩散电极也可以利用这些分散液和膜溶液。


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。

Pention-S72-5wt%/10wt%/20wt%是在有机溶剂中聚合物浓度分别为5wt%、10wt%、20wt%的无功能阴离子溶液。该聚合物溶液均属于S72系列。其IEC(meq/g)为0,因为其非功能化形式,根据功能化程度,可以很容易地获得IEC(meq/g)为1-3.5的功能溶液。非功能化聚合物溶液产品很适合制造不同厚度值的自支撑膜或机械增强膜。膜形成后,需要对其进行官能化,以便传导离子(阴离子)。功能化程序可以在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进行的研究中找到。


Pention系列阴离子膜溶液可用于各种电化学应用,包括燃料电池、电解槽、传感器、流动电池和各种其他电化学应用/技术。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系列分散体(也称离聚物)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

Pention solutions are the unfunctionalized dissolved polymer resin products that are used to manufacture anion conducting self-supporting membranes or mechanically reinforced membranes. The polymer 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. Functionalized dispersion products can be found here.

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


Pention-S72-5wt% is an unfunctionalized solution with 5wt% polymer concentration in an organic solvent. This polymer solution belongs to S72 series. This product has an IEC (meq/g) of 0 in for its unfunctionalized form and depending on the level of functionalization, IEC of 1 to 3.5 can easily be obtained. Unfunctionalized polymer solution products are highly suitable for manufacturing self-supporting membranes or mechanically reinforced membranes with different thickness values. After the formation of the membrane, it needs to be functionalized in order to conduct ions (anions). Functionalization procedure can be found in the jointly conducted study between NREL, University of South Carolina, and Georgia Institute of Technology.


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.


Key Advantages of Pention Solutions:

Enables to obtaines anion exchange membranes with very high conductivity
Great chemical stability
High performance for fuel cells and electrolyzers


Pention solutions/dispersions are considered hazardous items under DOT and IATA regulation. 125 mL and 250 mL solution/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 solutions/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.
