Fig. 5

a Static flexibility of a 9-nm-thick UTAF with different folding radii. The inset photograph presents of the flexibility test unit. b Folding stability of the electrical conductance of a 9-nm-thick UTAF and commercial ITO within 105 cycles. Insets show the SEM images and photographs of the ITO and UTAF after 104 cycles and 105 cycles, respectively. Scale bars in insets: 25 μm in left photographs; 100 nm in right SEM images. c Proof-of-concept demonstration of a foldable resistive touch panel. d 3D scheme for the configuration of a foldable ACEL device. e Luminance plot of a foldable ACEL device with changing folding curvature. The ACEL device is driven by a sinusoidal signal (160 V, 16 kHz). The inset picture shows a folded ACEL device with an HNU logo. f Luminance stability of the ACEL device undergoing a cyclic folding test. Inset images present the unfolding and folding states for the working ACEL device.
