Zigzag graphene nanoribbons: Flexible and robust transparent conductors

► Bending deformation on the transport and optic properties of ZGNRs. ► The transport properties of ZGNRs are insensitive to bending deformations. ► Absorption in the region of visible light is insensitive to bending deformations. ► Bending deformations induce optical absorption in the infrared region.
