In Figure 2a [1], the SEM measurements show that the CN nanosheets are closely packed. However, the morphology did not sustain after adding the TDP monomer (change from nanosheets to irregular, rough surface nanoparticles). At the same time, Figure 2b shows magnified irregular nanoparticles with an average diameter of 70–100 nm for CN-TDPx. Asymmetrical, thick, and compressed nanosheets can be seen in Figure 2c for CN, while suppressed surface morphology was observed for CN-TDP7.0, with transparent, smooth, tinny, and much-reduced size, as well as silk-like nanostructures for CN-TDP7.0 (Figure 2d).
