General description

Nafion™ membranes are fluorinated polymers functionalized with sulphonic acid moieties.

Application

Nafion™ membrane may be used in the fabrication of electrodes by dry plasma.
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.

Packaging

Darkening/browning is common for pieces stored in a general room environment for an extended period of time (several months), due to organics pick-up. Verify product is kept sealed during storage.
· Keep pieces sealed and protected from general exposure will reduce the effect. Recommend long term storage in air-tight bags.
· Discoloration does not affect performance and can be removed by soaking in dilute nitric acid.
Packaged in a heat-sealed foil bag in stay-flat mailers

Other Notes

Surface that is shiny and smooth must be installed facing the cathode; otherwise the membrane may be irreversibly damaged upon use.
