Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Application

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.

Nafion® was used to modify membranes in the study of transport phenomena. Nafion® solution was used as an electrolyte in studying the catalytic activity of PtIr electrocatalysts. The suspension was also used in the preparation of Aldose dehydrogenase (ALDH) bioanode. It was used in another study as a component of electrolyte in investigation of mechanico-electrochemical failure modes of the Fe interconnects. 3

Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis. These documents are located on the product detail page under Useful Links & Tools. Click on the following link to search for a Certificate of Analysis. Please click the following link to see the details on our Product Dating Information.
How do I get lot-specific information or a Certificate of Analysis?
A Certificate of Analysis is available by lot number and can be obtained through our Advanced Search Option: http://www.sigmaaldrich.com/catalog/AdvancedSearchPage.do
What is the average molecular weight of Product 274704, Nafion?
According to sources from Dupont, they have indicated that the molecular weight is very difficult to measure and would not give out a value.  However, they did provide us with an estimated value of 100,000 and indicated that it is likely to be a very rough estimation.  Information on the number average molecular weight or polydispersity is not available.
What is the viscosity of Product 274704, Nafion?
The viscosity is 23-35 centipoise at 20 deg C.
Do you know the full identity of the solvent used to make Product 274704, Nafion?
The mixture of lower aliphatic alcohol is predominately Isopropanol and n-Propanol and 15-20% water.  The ratio of the alcohols is 55 : 45 (Isopropanol : n-Propanol)
Do you have a method for using Product 274704, Nafion, for casting a film?
We do not have method or procedure for casting films, however, it has been noted that after evaporating the solvent, you would need to cure the film at 70-90 deg C for 30-60 minutes or the film will redissolve.
What is the particle size of Product 274704, Nafion, in the solvated state?
The Nafion ion exchange resin is not a true solution.  There are micelles of 50-100 angstrom present.
How do I find price and availability?
There are several ways to find pricing and availability for our products.  Once you log onto our website, you will find the price and availability displayed on the product detail page.
