Abstract
The invention relates to a novel film, membrane or powder media made from fluoropolymers, especially PVDF-based and ETFE-based polymers, which are suitable for separating gases, especially carbon dioxide, from a gas mixture. The novel film has good selectivity, high permeance, good mechanical properties, and exhibits a high resistance to oxidant and acid attack. The separation film is especially useful in harsh and corrosive environments.
