Abstract

Chemical vapor deposition (CVD) was used to grow high-quality two-dimensional graphene, and graphene/PDMS and graphene/PET flexible transparent conductive film were prepared. These were used to study the relationship between conductivity and curvature of two-dimensional graphene in the context of different materials and different thickness of the substrate. The results show that elastic modulus and thickness of the flexible substrate have little effect on conductivity of the two-dimensional graphene. When thickness of the substrate is the same, graphene resistance increases with the increase of the bending curvature. However, the rate of relative change of graphene resistance is small, indicating that two dimensional graphene conductive films can be used as flexible conductors for bendable touching screen, robot skin, and wearable device.

Key words： graphene; chemical vapor deposition; flexible transparent conductive film; conductivity
