Scanning transmission electron microscopy high-angle annular dark-field (STEM-HAADF) images of the different chitosan and chitosan/carboxymethyl cellulose (CMC)-based nanocomposite films. The yellow arrows indicate a feature possibly due to CNCs not fully dispersed in the matrix; the blue arrows indicate 3D microstructural domains formed by SPT and GO. The scale bar for the first and third column of images (magnification 31.8 k ×) represents 500 nm and the scale bar for the second and fourth column of images (magnification 180 k ×) represents 100 nm
