Abstract:
1. A method of preparing an electrolyte membrane comprising a crosslinked object of a polybenzoxazine-based compound formed of a polymerized resultant product of a first benzoxazine-based monomer represented by Formula 1 below or a second benzoxazine-based monomer represented by Formula 2 below with a crosslinkable compound, the method comprising: mixing the first benzoxazine-based monomer of Formula 1 or the second benzoxazine-based monomer of Formula 2 with the crosslinkable compound to form a resultant mixture, the crosslinkable compound including at least one of a polybenzimidazole, a polybenzthiazole, a polybenzoxazole, and a polyimide; and curing the resultant mixture to form a resultant, and then impregnating the resultant with a proton conductor: wherein, R R wherein, R R
