Figure 2: Fabrication of ANG nanogels bearing unsaturated double bonds.
From: Nano-structured smart hydrogels with rapid response and high elasticity
(a) Effects of polymerization time and temperature on the average hydrodynamic diameters of ANG nanogels in water detected by dynamic light scattering. (b) TEM micrograph of dried nanogels (ANG30), in which the randomly distributed dark dots with average diameter of ~6 nm in the shadow area are the ANG nanogels. Scale bar, 20 nm. (c) Effect of polymerization time on the concentration of unsaturated double bonds in the ANG dispersions (CC=C). (d) FT-IR spectra of thoroughly dialyzed ANG nanogels prepared with polymerization time (tp) of 10, 20, 30 and 40 min respectively, in which the peak at 981 cm−1 refers to unsaturated double bonds.
