Figure 6.
(a) Picture of the outer and inner bending test system and resistance changes during outer and inner bending as a function of bending radius. (b) Surface FESEM image of OC-Ag NW network film after a 3 mm radius outer bending test. Arrows indicate the regions separated by cracks. (d) Dynamic outer and inner bending fatigue tests of OC-Ag NW network films at a fixed bending radius of 5 mm. (d) Twisting test of the OC-Ag network film at a twist angle of 10° with inset picture showing twisting steps. (e) Rolling test of OC-Ag network films with increasing rolling cycles; the inset picture shows the rolling step.
