“…This result is controversial, because we assume that double bond formation after reduction should decrease the defects. Also, the shift in D and G band peaks toward lower wavelengths is evidence to support the reduction of graphene oxide [33]. As shown in Figure 3b, both D and G bands were shifted to lower wavelengths, compared to GO.…”

. (2013). Facile synthesis of reduced graphene oxide/MWNTs nanocomposite supercapacitor materials tested as electrophoretically deposited films on glassy carbon electrodes. Journal of Applied Electrochemistry, 43 (9), 865-877.Facile synthesis of reduced graphene oxide/MWNTs nanocomposite supercapacitor materials tested as electrophoretically deposited films on glassy carbon electrodes AbstractThis paper reports on a facile synthesis method for reduced graphene oxide (rGO)/multi-walled carbon nanotubes (MWNTs) nanocomposites. The initial step involves the use of graphene oxide to disperse the MWNTs, with subsequent reduction of the resultant graphene oxide/MWNTs composites using l-ascorbic acid (LAA) as a mild reductant. Reduction by LAA preserves the interaction between the rGO sheets and MWNTs. The dispersion-containing rGO/MWNTs composites was characterized and electrophoretically deposited anodically onto glassy carbon electrodes to form high surface area films for capacitance testing. Pseudo capacitance peaks were observed in the rGO/MWNTs composite electrodes, resulting in superior performance with capacitance values up to 134.3 F g-1 recorded. This capacitance value is higher than those observed for LAA-reduced GO (LAA-rGO) (63.5 F g-1), electrochemically reduced GO (EC-rGO) (27.6 F g-1), or electrochemically reduced GO/MWNTs (EC-rGO/MWNTs) (98.4 F g-1)-based electrodes.

“…As a result, the tensile strength of fibers prepared by melt spinning of the Nylon-graphene composite were increased 2.1-fold and the Young's modulus 2.4-fold with a graphene loading of only 0.1%. 91 The availability of stable dispersions of CCG particularly in organic solvents has led to the covalent attachment of polymers to CCG by way of in situ polymerization. Sayyar et al have prepared covalently functionalized polycaprolactone-CCG composites and compared them with the analogous solution processed composites.…”

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.

Graphene has wide potential applications in energyrelated systems, mainly because of its unique atom-thick twodimensional structure, high electrical or thermal conductivity, optical transparency, great mechanical strength, inherent flexibility, and huge specific surface area. For this purpose, graphene materials are frequently blended with polymers to form composites, especially when fabricating flexible devices. Graphene/polymer composites have been explored as electrodes of supercapacitors or lithium ion batteries, counter electrodes of dye-sensitized solar cells, transparent conducting electrodes and active layers of organic solar cells, catalytic electrodes, and polymer electrolyte membranes of fuel cells. In this review, we summarize the recent advances on the synthesis and applications of graphene/polymer composites for energy applications. The challenges and prospects in this field have also been discussed. V C 2012 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2013, 51, 231-253 KEYWORDS: composites; energy; fuel cell; graphene; lithium ion battery; redox polymers; solar cell; supercapacitor; synthesis INTRODUCTION Energy is one of the most important recent topics of concern to human society. To replace conventional fossil fuels, clean and renewable energies based on sunlight, wind, new chemicals, and biofuels are urgently demanded. Therefore, materials that can directly convert or store renewable energies are being extensively studied. Among them, graphene has recently attracted a great deal of attention because of its unique atom-thick two-dimensional (2D) structure 1,2 and excellent electrical, 2 thermal, 3 optical, and mechanical properties. 4,5 Graphene is a promising material for applications in various energy-related systems such as supercapacitors, 6-9 secondary batteries, 10-14 solar cells, 15-17 and fuel cells. [18][19][20] For this purpose, graphene materials are frequently blended with polymers to form functional composites. [21][22][23] The polymer component can improve the processability and/or flexibility of graphene materials, and also possibly provide them with new functions. To date, various graphene composites with insulating or conducting polymers (CPs) have been prepared through noncovalent 22 or covalent approaches. 24 They have also been applied as electrodes for supercapacitors and lithium ion batteries (LIBs), 25-29 counter electrodes of dye-sensitized solar cells (DSSCs), 15,30,31 and transparent conducting electrodes (TCEs) 32,33 or active layers of organic solar cells, 34 catalytic electrodes, and polymer electrolyte membranes of fuel cells. [35][36][37] This review focuses on summarizing the recent advances in the synthesis of graphene/polymer composites and their energy applications.
