Graphene oxide (GO) nanoparticles were incorporated in PVA/PVP blend polymers for the preparation of nanocomposite polymer films by the solution cast technique. XRD, FTIR, DSC, SEM, and UV-visible studies were performed on the prepared nanocomposite polymer films. XRD revealed the amorphous nature of the prepared films. ermal analysis of the nanocomposite polymer films was analyzed by DSC. SEM revealed the morphological features and the degree of roughness of the samples. DC conductivity studies were under taken on the samples, and the conductivity was found to be 6.13 × 10 −4 S·cm −1 for the polymer film prepared at room temperature. A solid-state battery has been fabricated with the chemical composition of Mg + /(PVA/PVP : GO)/(I 2 + C + electrolyte), and its cell parameters like power density and current density were calculated.

“…The nanosheets, both of GO (with or without functionalization) and graphene, can be dispersed into the common solvents (polymer soluble), and mix with the polymer directly. Poly (vinyl acetate), as a common matrix, has been studied widely due to its water solubility [64][65][66]. Since GO can be dispersed in water easily, it can be incorporated into aqueous polymer dispersion at different concentrations.…”

Abstract:Graphene, as an intermediate phase between fullerene and carbon nanotube, has aroused much interests among the scientific community due to its outstanding electronic, mechanical, and thermal properties. With excellent electrical conductivity of 6000 S/cm, which is independent on chirality, graphene is a promising material for high-performance nanoelectronics, transparent conductor, as well as polymer composites. On account of its Young's Modulus of 1 TPa and ultimate strength of 130 GPa, isolated graphene sheet is considered to be among the strongest materials ever measured. Comparable with the single-walled carbon nanotube bundle, graphene has a thermal conductivity of 5000 W/(m·K), which suggests a potential application of graphene in polymer matrix for improving thermal properties of the graphene/polymer composite. Furthermore, graphene exhibits a very high surface area, up to a value of 2630 m 2 /g. All of these outstanding properties suggest a wide application for this nanometer-thick, two-dimensional carbon material. This review article presents an overview of the significant advancement in graphene research: preparation, functionalization as well as the properties of graphene will be discussed. In addition, the feasibility and potential applications of graphene in areas, such as sensors, nanoelectronics and nanocomposites materials, will also be reviewed.

IntroductionDue to the rapid development of nanoscience and nanotechnology in the past 20 years, improvement of polymer properties by nanofillers has become a vital topic in the field of material science. [1][2][3] The polymer nanocomposites show enhanced properties by the incorporation of low amount of nanofillers such as carbon black (CB), carbon nanotubes (CNTs), graphene and nanoclay. [4][5][6][7] Due to the high surface to volume ratio and/or high aspect ratio, the nanofillers are more efficient than the traditional fillers in reinforcing polymers. 8,9 Among the nanofillers, graphene is an atomically thick, 2D nanomaterial that is the strongest materials measured so far. it has intensively attracted a great deal of interest in extensively exploring its applications. The superior properties of graphene also reflected in the graphene/polymer nanocomposites. It has been widely reported that the mechanical, thermal, electrical, gas-barrier and flame-retardant properties of polymer can be significantly improved by the addition of graphene. 3,6,[18][19][20][21][22][23][24] Its advantages over other nanofillers have been discussed. 3,19,[25][26][27][28] However, the reinforcing efficiency of graphene highly depends on the dispersion and distribution of graphene sheets in the polymer matrix. 29 An optimized graphene-polymer interface is critical in the property transfer. [30][31][32] Pristine graphene sheets are not compatible with organic polymers and have a great tendency to agglomerate in the matrix. 3,33,34 To resolve this problem, functionalization of graphene is an essential step to achieve a molecular level dispersion.3,35 The functionalized graphene (FG) sheets could form strong interfacial bonding with polymer chains, which is favorable for load transfer, but it also confines the motion of interfacial polymer segments. [36][37][38] Thus, the enhancements in stiffness, tensile strength and hardness of polymer are frequently reported, while the elongation at break and ductility is always decreased. 3,6,39 Toughness of polymer is extremely important in the critical structural applications and highperformance areas such as automotive, aerospace and defence. 9,40 Enhancing the toughness of polymer has been a challenging issue, especially for thermosets that have highly cross-linked structure. 9Traditional fillers, such as rubber particles, can improve the toughness, but they show negative impact on mechanical properties and manufacturability. 38,41 In the past few years, toughening of polymers by graphene has been explored and reported in a few publications. 25,[29][30][31][32]38,[42][43][44][45][46][47][48][49][50][51][52][53][54][55] According to the results, it is believed that the incorporation of FG can toughen polymers including both thermoplastics and thermosets, although the understanding of the mechanism is still insufficient.
