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 resin solution is widely used as an electrolytic material. It can be used in the formation of a composite membrane with metal oxides. The membrane further facilitates the formation of chemically stable proton exchange membrane (PEM) fuel cells. It may be coated on mesoporous metallic films to improve the detection and selectivity of biomarkers. It may also form a composite electrode material with graphene for glucose biosensors.
Nafion™ resin was used to produce nanometer thick Nafion™ layers on silane treated slides by the solution casting method.
Support material for an integrated system which used solar energy to drive chemical reactions. Acts as a superacid catalyst for organic synthesis. When formed as metal composites, can be used as artificial muscle actuators, solid electrolytes for the analysis of electroactive species in organic media, or as electrodes in organic electrosynthesis.
