Fluorinated crosslinked thermally rearranged gas separation membrane and preparation method thereof

摘要

The present invention relates to a thermally-converting polymer gas separation membrane having a fluorinated cross-linking structure and a method for producing the same, wherein the fluorine-bridged thermally-decomposing polymer gas separation membrane produced by the present invention has a fluorine- A fluorine deposition layer distributed so as to have a gradient; Transition layer; And a thermally-exchangeable polymer base layer, the selectivity is remarkably increased as compared with a conventionally commercialized gas separation membrane, and commercialization is possible.
