abstract：:The polymerization of N-isopropylacrylamide (NIPAAm) with ionizable monomers results in pH-responsive lower critical solution temperature (LCST) polymer which works in an ionization-dependent manner. However, gradual ionization of the comonomer occurs at a broad pH range due to the electrostatic field generated by the...
