(a) is the 1H NMR spectra of the poly(NIPAAm-co-AAc) microgel particles. Instet figure is the chemical structures of the as-synthesized microgel; (b,c) Field emmision scanning electron microscopy images of microgel particles in two different magnifications (magnification = 50,000× and 160,000×, respectively).
