a) Schematic of the EISA process to prepare CNC films on porous mesh substrates. As the water evaporates, the CNC concentration increases promoting their self‐assembly into chiral nematic tactoids, eventually merging to form a bulk chiral nematic phase. b) The resulting films are highly elastic, and exhibit the characteristic iridescence and c) chiral nematic structuring, as evidenced by SEM. d) The incorporation of PEG as a plasticizer leads to increased film uniformity and e) an increase in the peak reflectance wavelength. a) Adapted with permission.[ 103 ] Copyright 2017, Wiley‐VCH. b–d) Adapted with permission.[ 104 ] Copyright 2019, Wiley‐VCH.
