Abstract

Polyethylene terephthalate nuclear track membranes were subjected to radiofrequency low pressure plasma treatments in ammonia. The modification of morphology, chemical composition, and of water flow across membranes was investigated, in relation with the applied power, gas pressure, and treatment duration. The plasma treatments lead to modification of water permeability through membranes, opening a way for improving their transport properties..
