Figure 4

(a) SEM images of PMMA R2R nanoimprinted moth-eye structures fabricated at web speed of 0.5 m·min−1 and different temperatures as indicated. SEM images were acquired at a tilting angle of 45° with an equivalent rotation angle in all cases. The bottom row shows 3D reconstruction of AFM height images of areas ca. 550 × 550 nm2. (b) AFM surface profiles corresponding to selected substrates processed at the indicated temperatures. (c) Height dependence of the nanofeatures with processing temperature.
