Graphene fibers made from a graphene film formed into an elongated fiber-like shape and composite materials made from the graphene fibers. The elongated fiber-like shape may be the graphene film in a rolled spiral orientation or the graphene film in a twisted formation. The graphene film has imide groups formed on at least an outer surface of the graphene film. Methods of increasing strength of a composite material include combining a resin matrix with a plurality of the graphene fibers to form a prepreg material and curing the prepreg material to form the composite material.

The present invention relates to a microfluidic flow process for making monomers, monomers made by such processes, and methods of using such monomers. In such process, microfluidic reaction technology is used to synthesize cyanation reaction products orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does require strictly regulated, highly toxic cyanogen chloride. Thus the aforementioned process is more economically efficient and reduces the environmental impact of thermosetting resin monomer production, and produces thermosetting resin monomers in greater purity than obtained through typical processes.
