(A) Summary of the CFT as a function of PiPrOxA MW for free polymer and 9.1 nm iron oxide nanoparticles grafted with PiPrOxA measured in Milli-Q water by DLS as the temperature at which aggregation starts (the onset of the transition in the count rate curve). Black circles, free PiPrOxA (1 g L^–1); pink triangles, PiPrOxA-grafted iron oxide nanoparticles (5 × 10¹³ particles mL^–1); green squares, PiPrOxA-grafted iron oxide nanoparticles (1 g L^–1). (B) DSC curves for 21 kg mol^–1 MW PiPrOxA at 1 mg mL^–1 for free polymer (black) showing one transition and PiPrOxA grafted to nanoparticles (red), showing multiple transitions.
