Scientific uses include exploitation of the electrochemical and ion exchange properties of Nafion, as well as sample conditioning for laboratory analysis. Nafion is closely related to Teflon but has been chemically modified to make it function as an ion exchange membrane while still retaining the physical and corrosion resistance properties of Teflon.
