ePTFE Mechanically Reinforced Anion Exchange Membrane,Ligand is based on TMA

INQUIRY
Catalog Number ACMA00062907
Description This is a mechanically reinforced anion exchange membrane and the mechanical reinforcement is based on ePTFE (also known as expanded PTFE). The Alkaline Anion Exchange Membrane with PTFE support for easier handleability and greater strength. Presence of the mechanical reinforcement increases the mechanical strength and also reduces swelling or physical dimension change compared to self-supporting counterparts. It is moderately basic (i.e., alkaline) and designed for use with supporting electrolyte.
Notice For Use This anion exchange membrane is supplied in dry form with the counter anion being chloride (Cl-) ion. Most standard applications would require this membrane to be converted to the hydroxide form by exposing them to a strong base (assuming that the ion of interest is OH- or hydroxyl ions). It is recommended to soak the membrane in a large bath of 1M KOH for 24 hours in order to convert the membrane from chloride form into the hydroxide form. This activation also helps in strengthening the membrane via crosslinking with KOH as identified by a recent NMR study.
