Abstract
Zwitterionic block copolymers having oppositely charged or chargeable terminal groups, and methods of making and using the same, are disclosed. The zwitterionic block copolymers can undergo microphase separation.
Claims19
A method for assembling a block copolymer comprising:
- providing a zwitterionic block copolymer comprising:
- a first terminal block comprising an amine and/or a protonated amine group at the terminal end thereof;
- and
- a second terminal block comprising a carboxylic acid and/or a deprotonated carboxylic acid group at the terminal end thereof;
- and
- annealing the zwitterionic block copolymer,
- wherein each of the first and second terminal blocks independently comprises polymerized monomers selected from the group consisting of ethylene, propylene, styrene, methyl(meth)acrylate, ethyl(meth)acrylate, butadiene, isoprene, and combinations thereof.
