Figure 14. (A) Schematic diagram of the formation of NSFCDs. (B) Schematic diagram of cross-linking between NSFCDs and PEGDA under UV irradiation. ¹H nuclear magnetic resonance (NMR) (C) and ¹³C NMR (D) spectra of NSFCDs. (E) TEM image of NSFCDs. (F) HRTEM image of NSFCDs. (G) Schematic diagram of polymer conformation in HPE. (A-G) Reprinted with permission from Ref.^[141]. Copyright © Elsevier. (H) Solvothermal synthesis of CDs from citric acid (CA) and ethylenediamine (EDA), and the subsequent reaction between CDs and PEG to produce (I) PEG-CDs (DCC and DMAP are 1,3-dicyclohexylcarbodiimide and 4-dimethyl aminopyridine, respectively). (J) TEM image of CDs and the inset HRTEM image. (K) TEM image of PEG-CDs and the inset HRTEM image. (L) Fourier transform infrared (FTIR) spectra of CDs and PEG-CDs.
