“…66,67 Mixing is the simplest approach to prepare graphene/polymer composites and it can be further subclassified into solution mixing [68][69][70][71] and melting mixing. 65,72 Solution mixing requires both graphene material and polymer to be stably dispersed in a common solvent.…”

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.

“…Dodecyl-substituted FCCG proved well-suited for blending with high volume engineering plastics such as linear low density polyethylene: the electrical resistivity decreased from 10 16 Ocm for pure linear low density polyethylene to 10 7 and 10 4 Ocm at 3 and 8 wt% FCCG, respectively. 98 Chung and co-workers 99 reported PS/CCG composites prepared without covalent modification to the graphene; sonication of a methanol solution of CCG with PS gave a colloidal suspension, which upon filtration, produced composite pellets with high conductivity (470 S m À1 ) at B2.5 vol% graphene, and dramatic improvement in the thermal stability of PS. These composites were intrinsically hole doped, having p-type characteristics at higher temperatures, with field effect transistor mobilities 2-5 times higher for holes (0.1-1 cm 2 V À1 s À1 ) than electrons.…”

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.

The paper presents the test results of the effect of modified graphene and multi-wall carbon nanotubes on the thermal and mechanical properties and flammability of acrylic rubber and styrene-butadiene rubber. The rubbers were cross-linked with the use of organic peroxide. Based on the test results obtained by optic and AFM methods, a relationship between the surface morphology of the nanocomposites obtained was presented. By means of thermal analysis methods (TG, DTG, DTA) and a microcalorimeter, it has been found that the nanofillers used considerably increase the thermal stability and decrease flammability of the nanocomposites. The mechanical properties of the elastomeric materials obtained depend on the type and content of nanofiller.
