Figure 7
(a) SEM images of PMMA R2R nanoimprinted moth-eye structures fabricated at constant roll temperature (T = 110 °C) and at different web speeds as noted. SEM images were acquired at a tilting angle of 45° with an equivalent rotation angle in all cases. Bottom row shows the 3D reconstruction of AFM scans of 550 × 550 nm2 areas. (b) AFM height profiles corresponding to selected processing temperatures. (c) Height dependence of the nanoscopic features with processing speed.
