摘要：

The suspension of chemically converted graphene (CCG) provides a cost-effective and facile approach to construct graphene-based materials. However, wrinkles and aggregates usually occur when transferring graphene from suspension to solid-state, which significantly alter the optical, electrical, and electrochemical properties of deposited graphene. Our effort is devoted to the control of the morphology of individual graphene sheet deposited on solid surfaces by the solvent evaporation. Here we have studied the effects of additional components (e.g., organic solvent and electrolyte) in the CCG suspension on the CCG morphology. It was found that the CCG sheets could be stitched together and the graphene monolayer could be flattened by the addition of appropriate additives to the CCG suspension.
