摘要：

The development of a transparent and stretchable electrode is critical to the realization of stretchable optoelectronic devices. In this study, a template-guided self-assembly is demonstrated for the integration of carbon nanotubes into 2D rhombic nanomesh films, where the deformation of the rhombic structure accommodates the strain, greatly improving the stretchability. In addition, the regular 2D nanomesh patterns greatly reduce the contact resistance and light scattering. Our rhombic carbon nanotube nanomesh films exhibited significantly lower sheet resistance (similar to 10 times) at a similar optical transmittance (78%), greater stretchability (similar to 8 times less resistance increase at 30% strain), and better mechanical durability (similar to 42 times less resistance increase after 500 stretching cycles at a strain of 30%) than those of random-network carbon nanotube films.
