“…Considerable work has been carried out in this area and the reader is directed to a number of significant reviews on this topic. [93][94][95][96][97] FABRICATION OF GRAPHENE-CONTAINING STRUCTURES AND DEVICES Accompanying the development of processable graphenes has been substantial interest in the fabrication of graphene-based functional devices using printing (ink-jet and extrusion) and fiber spinning. The key challenges in printing and spinning graphene are production of suitable graphene dispersions, formulation of these dispersions into Graphene: enabling processing and fabrication S Gambhir et al printing inks or spinning solutions and a fabrication technique.…”

Graphene, a nanocarbon with exceptional physical and electronic properties, has the potential to be utilized in a myriad of applications and devices. However, this will only be achieved if scalable, processable forms of graphene are developed along with ways to fabricate these forms into material structures and devices. In this review, we provide a comprehensive overview of the chemistries suitable for the development of aqueous and organic solvent graphene dispersions and their use for the preparation of a variety of polymer composites, materials useful for the fabrication of graphene-containing structures and devices. Fabrication of the processable graphene dispersions or composites by printing (inkjet and extrusion) or spinning methods (wet) is reviewed. The preparation and fabrication of liquid crystalline graphene oxide dispersions whose unique rheologies allow the creation of graphene-containing structures by a wide range of industrially scalable fabrication techniques such as spinning (wet and dry), printing (ink-jet and extrusion) and coating (spray and electrospray) is also reviewed.

“…It is also highly transparent (97.3%) and extremely lightweight. Due to these remarkable properties, a large variety of applications seems possible, including the creation of new materials and innovative electronic products 4 . The properties of graphene are very dependent on its structure and therefore it is of great importance investigating methodologies for producing large quantities of single layer graphene.…”

Few Layer Reduced Graphene Oxide: Evaluation of the Best Experimental Conditions for Easy Production

et al. 2016

This work aimed to produce graphene oxide with few graphene layers, a low number of defects, good conductivity and reasonable amount of oxygen, adequate for use as filler in polymeric composites. Two starting materials were evaluated: expanded graphite and graphite flakes. The method of oxidation used was the Staudenmaier one, which was tested over different lengths of time. No appreciable differences were found among the oxidation times and so the lowest oxidation time (24 h) was chosen as the most adequate. An investigation was also conducted into suitable temperatures for the reduction of graphite oxide. A temperature of 1000 ºC gave the best results, allowing a good quality material with few defects to be obtained. The reduction was also evaluated under inert and normal atmosphere. The best results were obtained when the least modified material, e. g., graphite flakes, was used as a starting material, oxidized for 24h and reduced at 1000 ºC for 30 s in a quartz ampoule under a normal atmosphere.

“…GO can be directly intercalated with hydrophilic polymers, such as poly(vinyl alcohol) and poly(ethylene oxide), while composites with hydrophobic polymers, such as polystyrene (PS) are achieved by polymerization in the presence of GO, 91 or by grafting from the graphene surface. 92 Thermal or chemical reduction of GO within a polymer matrix restores the p-conjugation of platelets, giving 'reduced GO' , which has a C:O ratio of 10:1, indicating residual defects as a result of incomplete reduction. 93 Recent work seeks to maintain the pristine graphene framework while accessing exfoliated, single graphene sheets by selective edge-functionalization using Friedel ÀCrafts acylation, 94 and by recovering conductivity through mild conditions, such as flash photolysis.…”

Harnessing synthetic power to create novel materials with unique assembly properties is of fundamental interest for pushing the limits of molecular and macromolecular assembly, while further holding the potential for improving electronic and medical device performance. Controlling the assembly of aromatic molecules into nanostructures provides routes towards continuous and extended structures with performance that is improved markedly over that of their individual molecular components, opening possibilities for the formation of composites that have tailored interactions with other materials and thus improved applications. This review covers recent advances in the synthesis of conjugated materials, their controlled assembly into nanoscale architectures and implementation into devices. Specifically, we discuss the solution-based assembly of polythiophene into nanowire fibrils, the formation of columnar stacks of hexabenzocoronene liquid crystals and the preparation of functionalized solution processible graphene for nanocomposite formation.
