本发明涉及种从氟聚合物、尤其是基于PVDF和基于ETFE的聚合物制成的新型的薄膜、隔膜或粉末介质，这些聚合物适用于将气体、尤其是二氧化碳从气体混合物中分离出来。该新型薄膜具有良好的选择性、高的渗透性、良好的机械性能，并且展现高的氧化剂和酸侵蚀的耐性。该分离薄膜尤其在严苛的并且腐蚀性的环境中是有用的。 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.
