(a) Scanning electron microscopy image of CNF nanopaper. Scale bar: 500 nm. (b) Transmittance spectra of nanopaper: as prepared (black); cured at 100°C (red); cured at 150°C (violet); cured at 180°C (blue). Nanopaper retained excellent light transmittance after curing. (c) Appearance of a 20 μm thick transparent CNP after 180°C curing. Reproduced from reference [23] with permission from John Wiley & Sons.
