    摘要： Disclosed herein are a method for preparing a benzoxazole-based polymer by thermal rearrangement, the benzoxazole-based polymer prepared by the method and a gas separation membrane comprising the polymer. More specifically, provided are a method for preparing a benzoxazole-based polymer by subjecting poly(hydroxyamide) as an intermediate to thermal treatment involving dehydration, the benzoxazole-based polymer obtained thereby and gas separation membrane comprising the polymer. The benzoxazole-based polymer of the present invention can be simply prepared by thermally rearrangement via thermal treatment at low temperatures, and thus exhibits superior mechanical and morphological properties and has well-connected microcavities. Due to showing excellent permeability and selectivity for various gases, the benzoxazole-based polymer is suited for application to gas separation membranes, in particular, gas separation membranes for small gases.

    摘要： Disclosed herein are a polyimide-polybenzoxazole copolymer, a method for preparing thereof and a gas separation membrane comprising the same. More specifically, provided are a polyimide-polybenzoxazole copolymer simply prepared through thermal-rearrangement performed by thermally treating a polyimide-poly (hydroxyimide) copolymer as a precursor, a method for preparing the same, and a gas separation membrane comprising the same. The copolymer shows superior gas permeability and gas selectivity, thus being suitable for use in gas separation membranes in various forms such as films, fibers or hollow fibers. The gas separation membrane thus prepared can advantageously endure even harsh conditions such as long operation time acidic conditions and high humidity due to the rigid polymer backbone present in the copolymer.

    摘要： A proton exchange polymer membrane whose surface is treated by direct fluorination using a fluorine gas, a membrane-electrode assembly, and a fuel cell comprising the same are provided. The proton exchange polymer membrane of the present invention exhibits improved proton conductivity, high dimensional stability, and decreased methanol permeability through introducing hydrophobic fluorine having high electronegativity to the surface of the polymer membrane. Therefore, the proton exchange polymer membrane with excellent electrochemical properties of the present invention can be preferably utilized as polymer electrolyte membrane for fuel cell, generating electric energy from chemical energy of fuels.
