Abstract: The filtration material includes a supporting layer, a first selective layer disposed on the supporting layer, and a second selective layer disposed on the first selective layer. The first selective layer includes a polyimide and an ionic polymer intertwined with the polyimide. In particular, the polyimide includes at least one repeat unit having a structure represented by Formula (I) wherein A1 is A2 is R1 and R2 are independently —H, —CF3, —OH, —Br, —Cl, —F, C1-6 alkyl group, or C1-6 alkoxy group; and X and Y are independently single bond, —O—, —CH2—, —C(CH3)2—, or —NH—.
