Polyethylene water vapor permeability
WebTFC membranes fabricated by interfacial polymerization (IP) show the better performances than other techniques for gas separation. Conditions for interfacial polymerization process to be efficiently utilized in permeation of water vapor were optimized to achieve the higher permeance and selectivity. WebThe backing film may be gas or moisture permeable to allow the sugar-based oxygen scavenging component to travel to the surrounding environment. For example, a high-density polyethylene film, such as a nonwoven film (e.g. TYVEK® by DuPont de Nemours, Inc.), may be used as a gas permeable backing film.
