Assembly of an unbalanced charged polyampholyte onto Nafion® to produce high-performance composite membranes

Chem Commun (Camb). 2012 Dec 28;48(100):12201-3. doi: 10.1039/c2cc36871d.

Abstract

A novel SPES-NH(2)-GA-Nafion® composite membrane with higher proton conductivity and lower methanol permeability was fabricated by covalent crosslinking layer-by-layer self-assembly of an unbalanced charged polyampholyte (SPES-NH(2)) and glutaraldehyde (GA) with controllable free sulfonic acid content.
