PolyvinylChloride Nafion Membrane, Thickness : 0.2 To 0.8

Nafion™ 117 Membrane

The Nafion™ 117 membrane is a perfluorosulfonic acid (PFSA) ion-exchange membrane widely used in electrochemical and energy applications. It is a chemically stable, proton-conductive polymer that serves as both an electrolyte and a separator, enabling ionic conductivity while preventing electronic conduction between electrodes.

Key Properties:

• Material: Perfluorosulfonic acid (PFSA) polymer

• Thickness: ~183 µm (7 mils)

• Equivalent Weight (EW): 1100 g/mol SO₃⁻

• Appearance: Transparent, mechanically robust film

• Ionic Conductivity: Excellent proton conductivity in hydrated state

• Chemical Resistance: Outstanding stability against acids, oxidizing agents, and solvents

Applications:

• Fuel Cells: Functions as a proton exchange membrane (PEM), conducting protons from anode to cathode while blocking gases.

• Electrolyzers: Used in water electrolysis for hydrogen production.

• Chlor-alkali Industry: Separation of anode and cathode chambers.

• Batteries & Sensors: Acts as an ion-conducting medium in advanced energy storage and sensing devices.

Advantages:

• High proton conductivity with low electrical conductivity

• Excellent chemical and mechanical durability

• Reliable long-term performance in harsh electrochemical environments
