NOVELTY - An ion transfer material comprises copolymer having units (I)-(IV) and inorganic particle dispersed in peripheral portion of sulfonic acid group-containing copolymer.    USE - Ion transfer material for use in electrolyte film, that is utilized in fuel cell and redox flow battery (all claimed), such as ion exchange film, ion transfer film, ion conductivity film, ion exchange separation film, ion transfer separation film, ion conductivity separation film, ion exchange electrolyte film, ion transfer electrolyte film or ion conductivity electrolyte film.    ADVANTAGE - The material has better ion conductivity, chemical resistance and mechanical property, improved performance of the ion transfer, better effects of reducing swelling phenomenon of the film by the solvent, preventing effect of the transmitted material which is generated according to the ion channel, and is simple and environment-friendly to manufacture.    DETAILED DESCRIPTION - An ion transfer material comprises inorganic particle dispersed in peripheral portion of sulfonic acid group-containing and copolymer having units of formulae (I)-(IV), where each of the units (I)-(IV) have fluorine substituent.    Z = trivalent aromatic ring or a trivalent heterocyclic;    L = direct bond or a divalent linking group, preferably -((CH2)m((CF2)2O(CF2)2)n)-;    X1-X3 = direct bond, O, -CO-, -SO2-, aryl, heteroaryl or asterisk-ZL-SO3R -;    asterisk = a portion that is connected to the main chain;    R= group I element in the periodic table;    Y1-Y22 = alkyl (optionally substituted), H or F; and    m, n = 0-5.    INDEPENDENT CLAIMS are also included for the following:    (1) an electrolyte film including the ion transfer material    (2) a method for manufacturing a electrolyte film, which involves preparing solution-A containing copolymer having unit of formula (V), units (II)-(IV), preparing a precursor solution-B comprising inorganic particles, mixing the solution-A and solution-B to obtain a mixed solution, and forming the mixed solution into the film.    X4-X6 = direct bond, O, -CO-, -SO2-, aryl, heteroaryl or alpha -ZL-SO3M -;    alpha = a portion that is connected to the main chain; and    M = alkali metal element.
