Thermoresponsive polymers as macromolecular coordination ligands: complexation-dependence of thermally induced aggregation in aqueous solution

Abstract

We have designed novel macromolecular coordination ligands (MCLs) by conjugation of thermoresponsive polymers based on poly(N-isopropylacrylamide) (M ̅_n around 3 to 25 kg∙mol-1) with 1,2,4-triazole coordination sites. These triazole units...

Thermo-responsive block copolymers: assembly and application

“…In the former case, the thermo-responsive polymers become hydrophobic from the hydrophilic state in solvents as temperature increases, while in the latter case thermo-responsive polymers become hydrophilic from the hydrophobic state. In the current literature, LCST-type thermo-responsive polymers are mostly studied, which mainly include polyacrylamides, [63][64][65] polyethylene oxides, [66][67][68][69] polyacrylates [70][71][72][73] and polyimidazoles, 43,74,75 which can undergo phase transition in water, and their applications in biomedical 76,77 and wastewater treatment 4,43,58 are investigated. UCST-type thermo-responsive polymers are mainly amphiphilic polyelectrolytes, such as polysulfone betaines, 78,79 poly(N-acryloyl glycinamide) 27,80 and ionic polypeptides.…”
