a Chain extension of 2 kDa PEG macro-CTA with DEGMA to form a diblock copolymer, where ACVA denotes 4,4′-azobis(4-cyanovaleric acid). b VT-DLS of 5 mg mL− 1 PEG-b-PDEGMA in water heated from 25 °C (green) to 65 °C (red) and cooled to 25 °C (blue). c Single frames of VT-LCTEM experiment on 10 mg mL− 1 PEG-b-PDEGMA in water imaged at a flux of 0.8 e−Å− 2s− 1and heated to 60 °C. d Schematic of hydrophilic homopolymer chain-extension to yield a temperature-responsive diblock copolymer that reversibly undergoes assembly upon heating above the LCST. e Formation of vesicular assemblies at 65 °C during a VT-LCTEM experiment on PEG-b-PDEGMA.
