General description

2-Nitrophenyl octyl ether (NPOE) is an organic solvent, which is mainly used as a plasticizer and a charge transferring liquid that can be used in electrochemical devices. Its water solubility is low and has a high molar volume with a relative permittivity of 24.2.

Application

NPOE can be used as a plasticizer in a polymeric inclusion membrane (PIM) that enhances the transport of copper(II) in the solution of ammonia. It can be incorporated in a cellulose tri-acetate/carbon nanotube (CTA/CNT) based membrane, which is used in the transport and detection of melamine from milk samples.

Features and Benefits

May be used as a plasticizer for cellulose triacetate membranes providing impermeability to metal cations, but allowing anion exchange.
