长度 × 宽度：8 in. × 10 in. 应用： Nafion ™ 膜可用于通过干式等离子体技术制造电极。作为质子交换膜，Nafion ™ 已成为开发改良型燃料电池的工作重点。 全氟磺酸 ™ 膜(Nafion 117)是一种复合材料，可用作燃料电池制造的电解离子交换膜。 Nafion ™ 是一种具有广泛商业用途的全氟化离子交换膜。其酸性（氢离子）形式和衍生物为可用于许多合成应用的固体超强酸催化剂。 储存及稳定性： 储存方式为袋装密封。开封后，贮存 1 年以上可引起膜变黄。在大多数使用之前，只需在去离子水中浸泡 1/2 小时即可 Length x width 8 in. X 10 in. General Description： We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here . Application： Nafion ™ perfluorinated membrane (Nafion 117) is a composite material that can be used as an electrolytic ion-exchange membrane for the fabrication of fuel cells. Nafion ™ membrane may be used in the fabrication of electrodes by dry plasma.As a proton exchange membrane Nafion ™ has been the focus of considerable efforts to develop improved fuel cells. Nafion ™ is a perfluorinated ion-exchange membrane which has a wide variety of commercial uses. The acidic (hydrogen ion) form and derivatives are solid, superacid catalysts useful in a wide variety of synthetic applications. Storage and stability： Storage is sealed in bags. After opening, storage for more than 1 year can cause the film to turn yellow. Just soak in deionized water for 1/2 hour before most use
