Properties of diode-like membranes produced by plasma modification

Abstract

A new type of single bipolar membranes was obtained by plasma polymerization that possess asymmetry of conductivity − the effect of the current rectification similar to p-n transition in semiconductors. To produce membranes with diode-like properties, polymer layers formed from aniline by plasma were deposited on one side of poly(ethylene terephthalate) track membranes. In order to increase the rectification effect, this polymeric layer was doped by iodine.
