Abstract
A polymer includes an anchor group, a solvating segment, and an end group. The anchor group is any one or more selected from —COOR1, —SO3R2, or —PO(OR3)OR4. R1, R2, R3 and R4 each independently include a first group and a second group. The first group is H. The second group is any one or more selected from C1 to C12 alkyl, C6 to C20 aryl, or C5 to C20 heteroaryl. The solvating segment is any one or more selected from segments that include the following structural units.
