“…Linear and cross‐linked quenched polyampholytes (QPA) exhibit salt‐tolerant, 1 thermal‐resistant, 2 shear‐stable, 2 self‐healing, 3‐5 antifouling, 6,7 self‐assembling, 8‐11 and stimuli‐responsive, 12‐14 properties that provide broad impact as enhanced oil recovery (EOR), 15,16 and drag reduction agents, 17,18 structural biomaterials, 19 controlled delivery systems, 20,21 energy storage devices, 22 supercapacitors, 23 and actuators 24 . Synthetic protocol of QPA includes the conventional free‐radical copolymerization (FRP) of charged monomers, 1,25‐32 polymerization in microemulsion, 33‐39 polymerization of anionic‐cationic monomer pairs without counterions, 40 or zwitterionic monomers, 41 and reversible addition‐fragmentation chain transfer (RAFT) polymerization 7,14,42,43 . The QPA prepared in solution have a tendency to alternate between positively‐ and negatively‐charged monomers while prepared by means of a microemulsion polymerization allows to produce very high molecular weight copolymers (up to 1 × 10 7 g mol −1 ) that are more homogeneous in composition, with a reduced probability of continuous sequences of monomers of the same charge in the macromolecular chain.…”
