MOLECULAR TRANSPORT OF OXYGEN AND NITROGEN THROUGH POLYMER FILMS

Abstract
Molecular transport of oxygen (O2) and nitrogen (N2) through polymer films has been one of the major thrust areas of research over the past several years. With increasing demand for the use of synthetic polymers in engineering, medicine, surgery, separation science, agriculture, etc., different polymer backbones exhibiting superior transport properties have been synthesized. A great deal of effort has been focused on the surface modification of films in addition to introducing a variety of favorable functional groups on the polymer backbones which facilitates easy transport of gases, such as oxygen and nitrogen, and their separability.
