1. A method of forming a poly(diallylammonium) multiblock copolymer, comprising:
mixing a diallylammonium polymer functionalized on a first end and a second end with a first group, a first difunctional monomer functionalized with a second group, and a second difunctional monomer functionalized with a third group to form a mixture; and
reacting the mixture to form the poly(diallylammonium) multiblock copolymer,
wherein the first difunctional monomer is a halophenyl sulfone and the second difunctional monomer is a bisphenol.
