Application

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.
Nafion™ perfluorinated membrane is a composite membrane, which is utilized as an ion-exchange membrane for the fabrication of fuel cells. It can also be used as an electrolytic separator for the preparation of small scale supercapacitors.

General description

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

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 heat-sealed foil bag in stay-flat mailers

A low-cost optical sensor using an immobilized chromogenic redox reagent was devised for measuring the total antioxidant level in a liquid sample without requiring sample pretreatment. The reagent, copper(II)-neocuproine (Cu(II)-Nc) complex, was immobilized onto a cation-exchanger film of Nafion, and
