AFM images of composites: (a) 2D, (b) 3D, (c) phase contrast images of P₃, (d) 2D, (e) 3D, (f) phase contrast images of P₃ after 300 h exposure at UV, (g) 2D, and (h) 3D, (i) phase contrast images of P₃ after 600 h exposure at UV. Images were recorded on semicontact (tapping) mode (30×30 μm²) with resolution of 256×256 pixels.
