应用

Nafion™是一种全氟离子交换膜，具有多种商业用途。酸性（氢离子）形式和衍生物是固体超强酸催化剂，可用于多种合成应用中。
Nafion™ perfluorinated membrane is mainly used as a proton exchange membrane (PEM) for fuel cell applications. It can also be used as a membrane for lithium isotope separation, which can be further be utilized as a fuel for fusion reactors. It has excellent chemical stability and high cationic conductivity. It finds potential usage in batteries and sensors.
Surface that is shiny and smooth must be installed facing the cathode.

包装

由于有机物的吸收，在一般室内环境中长时间（几个月）存放的膜通常会变暗/变褐色。在储存期间，应确认产品是否保持密封。
· 保持膜密封并防止一般暴露，可减少有机物的影响。长期储存时，建议使用密封袋存放。
· 变色不影响性能，使用稀硝酸浸泡可除去颜色。
Packaged in a heat-sealed foil bag in stay-flat mailers.
