Figure 8

3D visualizations of AFM topographical images, representative of epoxy/ALNP surfaces—(a) before RF air plasma etching, (b) after etching for 20 min, (c) after etching for 45 min, and (d) after etching for 65 min. The insets contain schematic representations of nanostructure formation; roughness is provided for each etching stage.
