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.

Background: Three-dimensional assembly of graphene hydrogel is rapidly attracting the interest of researchers because of its wide range of applications in energy storage, electronics, electrochemistry, and waste water treatment. Information on the use of graphene hydrogel for biological purposes is lacking, so we conducted a preliminary study to determine the suitability of graphene hydrogel as a substrate for cell growth, which could potentially be used as building blocks for biomolecules and tissue engineering applications. Methods: A three-dimensional structure of graphene hydrogel was prepared via a simple hydrothermal method using two-dimensional large-area graphene oxide nanosheets as a precursor. Results: The concentration and lateral size of the graphene oxide nanosheets influenced the structure of the hydrogel. With larger-area graphene oxide nanosheets, the graphene hydrogel could be formed at a lower concentration. X-ray diffraction patterns revealed that the oxide functional groups on the graphene oxide nanosheets were reduced after hydrothermal treatment. The three-dimensional graphene hydrogel matrix was used as a scaffold for proliferation of a MG63 cell line. Conclusion: Guided filopodia protrusions of MG63 on the hydrogel were observed on the third day of cell culture, demonstrating compatibility of the graphene hydrogel structure for bioapplications.
