(a) Representative nanoindentation loading–unloading curves obtained for the nanoimprinted moth-eye films processed at 110 °C and at different web speeds. (b) Representative nanoscratch measurements obtained for normal applied load of 100 µN. Broadband optical performance of the R2R nanoimprinted substrates: (c) specular transmittance spectra and (d) total reflectance spectra. The dotted line corresponds to a two-sided nanoimprinted moth-eye PMMA film prepared at 110 °C and 0.05 m·min−1.
