Dual Temperature- and pH-Dependent Self-Assembly of Cellulose-Based Copolymer with a Pair of Complementary Grafts

Thermo- and pH-responsive micellization of HEC-g-(PNiPAAm&PAA) (CNiPAa) was studied. This binary graft copolymer CNipAa was synthesized via successive radical polymerization of N-isopropylacrylamide (NiPAAm) and acrylic acid (AA) from hydroxyethyl cellulose (HEC) as the backbone. The copolymers...

Zusammenfassung:	Thermo- and pH-responsive micellization of HEC-g-(PNiPAAm&PAA) (CNiPAa) was studied. This binary graft copolymer CNipAa was synthesized via successive radical polymerization of N-isopropylacrylamide (NiPAAm) and acrylic acid (AA) from hydroxyethyl cellulose (HEC) as the backbone. The copolymers are able to self-assembly into a trinity of micelles of different structures by combined pH and temperature stimuli: (1) at 30 °C and a low pH range (
