Surface morphology of the nanostructured paper is studied by AFM for 2-D height image (a) and 3-D height image (b) at the scan size of 2.5 μm × 2.5 μm. Optical transmittance curve (c) and optical haze (d, 550 nm) of the different nanostructured paper samples ranging from 400 nm to 1100 nm were compared. Digital images of the experimental equipment (e) and the fabricated nanostructured paper with dually high tranparency and haze (f).
