A separator for an electrochemical device comprising a porous polymer substrate, and a porous coating layer on at least one surface of the porous polymer substrate. The porous coating layer comprises inorganic particles and an ion conducting polymer. The ion conducting polymer comprises a fluorine-based copolymer comprising fluoroolefin-based segments with anionic functional groups present in side chains or terminals, and an electrochemical device comprising the same. It is possible to provide a separator with high ionic conductivity and an increased peel strength between the porous polymer substrate and the porous coating layer, and an electrochemical device with improved properties.

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.

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.

A coated polymer film, such as a coated polyester film, is disclosed. In one embodiment, the coated film may be used as a substrate for digital printing. In one embodiment, the coating contains an anionic anti-static agent comprising a sulphonated copolyester resin.
