## Description

- description: " Assembling graphene sheets into macroscopic fibers with graphitic
    layers uniaxially aligned along the fiber axis is of both fundamental and technological
    importance. However, the optimal performance of graphene-based fibers has been
    far lower than what is expected based on the properties of individual graphene.
    Here we show that both mechanical properties and electrical conductivity of graphene-based
    fibers can be significantly improved if bridges are created between graphene edges
    through covalent conjugating aromatic amide bonds. The improved electrical conductivity
    is likely due to extended electron conjugation over the aromatic amide bridged
    graphene sheets. The larger sheets also result in improved stacking, which, along
    with the robust aromatic amide linkage, provides high mechanical strength. In
    our experiments, graphene edges were bridged using the established wet-spinning
    technique in the presence of an aromatic amine linker, which selectively reacts
    to carboxyl groups at the graphene edge sites. This technique is already industrial
    and can be easily upscaled. Our methodology thus paves the way to the fabrication
    of high-performance macroscopic graphene fibers under optimal techno-economic
    and ecological conditions."
