a Schematic of the CDs-UPy preparation. b, c 13C NMR (b) and FTIR (c) spectra of the CDs (blue), UPy-NCO (olive), and CDs-UPy with α of 0.89 (black), 1.26 (gray), 1.51 (dark blue), 1.80 (dark cyan), and 2.30 (purple) mmol g-1. d Representative TEM image of the CDs-UPy with α of 2.30 (CDs-2.30UPy). The inset shows the diameter distribution of the CDs-2.30UPy by analyzing 100 CDs-UPy. The scale bar is 20 nm. e Representative AFM image of the CDs-UPy with α of 2.30 (CDs-2.30UPy). The scale bar is 3 μm. The left inset shows the height distribution of CDs-2.30UPy by analyzing 100 CDs-UPy. The right inset shows the enlarged AFM image of the CDs-2.30UPy. The scale bar is 500 nm. f DSC curves of the CDs-UPy with α of 0.89 (black), 1.26 (gray), 1.51 (dark blue), 1.80 (dark cyan), and 2.30 (purple) mmol g-1. Source data are provided as a Source Data file.
