  Described herein are articles for separating gases. The article includes a selective layer consisting of a crosslinked amorphous fluorinated copolymer containing one or more types of fluorinated ring monomers, with crosslinking between the fluorinated copolymer chains. The crosslinking improves the mechanical properties of the fluoropolymer, thereby permitting use of polymer types which would otherwise be excessively brittle. The resulting crosslinked polymer membranes have superior selectivity and reliability performance compared with previous compositions known to the art. Methods for making and using the article described are also provided.

  Described herein are optically transparent and semipermeable windows composed of at least one layer of an amorphous crosslinked fluorinated copolymer. Also disclosed are a process and apparatus for three-dimensional continuous liquid interface production (CLIP) printing using the windows described herein. The amorphous crosslinked fluorinated copolymers have improved mechanical properties, thereby reducing the susceptibility of the window to brittle failures such as cracking and crack propagation. The gas permeable windows have superior durability and reliability compared with other available structures and compositions.
