WebbThis behavior is ascribed to the salt concentration dependence of both the lower critical solution temperature (LCST) of PNIPAM, and the complex coacervation. Above 0.75 M NaCl, the PNIPAM blocks are insoluble in water at room temperature, while complexation between the polyelectrolytes is prevented because of charge screening by the salt. storage sheds in las cruces nmWebbFollowing this line of reasoning, thermoresponsive microgels that are formed with polymers that exhibit upper critical solution temperature (UCST) would exhibit swelling behavior at VPTT.
