Abstract
In addition, microfluidics-enabled assembling highly ordered multiscale graphene structures have been developed. The mechanistic study of rheology of graphene oxide fluid has been assisted through fine design of microfluidic channels. The motion of graphene oxide sheets during assembling process has been well controlled to optimize molecular orientation and macroscopic ordering of the graphitic domains in the final structures. During flow, two dimensional graphene oxide sheets show higher order of orientation in low aspect ratio microfluidic channels than circular channels. The obtained graphene belts from low aspect ratio microfluidic channels show perfect graphitic crystalline structure, achieving thermal conductivity up to 1600 W/mK and electrical conductivity of 9.3×106 S/m.
