Fig. 2: CLC-droplet-dispersed PVA films.
a Schematic illustration of oblate-CLC-droplet-dispersed PVA films with a gradient distribution of oblate CLC droplets perpendicular to the film plane and thus a gradient thermal expansion perpendicular to the film plane when oblate CLC droplets were heated to the isotropic phase. b An “octopus” on a black rock reversibly changed color from blue to colorless and shape from flat to curved for camouflage upon heating and cooling.
