More Information
Summary:Gas-permeable membranes comprising a microporous film and a coating on the microporous film, the coating being obtained by coating the microporous film with a liquid coating composition comprising a polymer and hollow polymeric particles dispersed in the composition, and then solidifying the coating. The gas-permeable membrane has a reduced ratio of carbon dioxide permeability to oxygen permeability.
