Abstract: A multi-branched cationic phosphonium salt is provided. The multi-branched cationic phosphonium salt has a structure represented by formula (I): {Z[P+(R1)(R2)(R3)]n}(X−)n  (I) wherein each of R1, R2, and R3 is independently a linear or branched C1˜C10 alkyl group, X− is an organic or inorganic anion, and Z has a structure represented by Formula (IIb) or Formula (IIc): wherein a is an integer of 1˜15. In Formulas (IIb) and (IIc), Z is connected to [P+(R1)(R2)(R3)] at the position marked by an asterisk (*), and n is an integer of 3˜4.
