Abstract:

Graphenes with varying number of layers can be synthesized by different strategies. Thus, single-layer graphene is obtained by the reduction of single layer graphene oxide, CVD and other methods besides micromechanical cleavage. Few-layer graphenes are prepared by the conversion of nanodiamond, arc-discharge of graphite and other means. We briefly present the various methods of synthesis and the nature of graphenes obtained. We then discuss the various properties of graphenes. The remarkable property of graphene of quenching fluorescence of aromatic molecules is shown to be associated with photo-induced electron transfer, on the basis of fluorescence decay and time-resolved transient absorption spectroscopic measurements. The interaction of electron donor and acceptor molecules with few-layer graphene samples has been discussed. Decoration of metal nano-particles on graphene sheets and the resulting changes in electronic structure are examined. Few-layer graphenes exhibit ferromagnetic features along with antiferromagnetic properties, independent of the method of preparation. Graphene-like MoS 2 and WS 2 have been prepared by chemical methods, and the materials are characterized by electron microscopy, atomic force microscopy (AFM) and other methods. Boron nitride analogues of graphene have been obtained by a simple chemical procedure starting with boric acid and urea and have been characterized by various techniques.

Abstract:

High electrical performances of polytetrafluoroethylene composites containing few-layer graphenes are established by solid-state processing. Polytetrafluoroethylene and FLG powders are mechanically mixed without solvents at room temperature, and hot-pressed. Few-layer graphenes are attached to the polytetrafluoroethylene powder, and gradually wrap the powder surface during milling with a low milling speed. The few-layer graphene-wrapped polytetrafluoroethylene powders readily facilitate the formation of a continuous few-layer graphene network due to the contact between adjacent few-layer graphene-wrapped powders. The final composites using few-layer graphene-wrapped polytetrafluoroethylene powders include a three-dimensional conducting network. Eventually, the wrapping morphology of the polytetrafluoroethylene/few-layer graphene powder results in a remarkable electrical conductivity of 7353 Sm−1 at 30 vol. %. few-layer graphene loading.

Abstract:

The buckling behavior of graphene on soft films has been extensively studied. However, to avoid graphene fracture, most studies focus only on the primary buckling behavior induced by tiny compression. Here, the buckling behavior of monolayer, three-layer, and four-layer graphene on soft films is systematically studied in the experiment under large compression. The cross-sections of buckling patterns in these few-layer graphenes are provided, which depend on focused ion beam (FIB) technology. More significantly, the moduli of few-layer graphene are calculated based on the buckling behavior. We demonstrate that the modulus, 1.12621 TPa, is independent of the number of graphene layers if the number is less than four. Our investigations are crucial for the application of two-dimensional (2D) materials into flexible hybrid electronics, bionics, and various other stiff/soft bilayer systems.

Abstract:

A novel method is presented to prepare few-layer graphene (FLG) in N-methyl-2-pyrrolidinone (NMP) by using a simple, low-cost and energy-effective shear exfoliation assisted by zeolite and using a cappuccino mixer to produce shear. We propose that the exfoliation of natural graphite flakes can be achieved using inelastic collisions between graphite flakes and zeolite particles in a dynamic colloidal fluid. To confirm the exfoliation of FLG, spectroscopy and morphological studies are carried out using Raman spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Additionally, the obtained graphene shows a linear flow of current and low resistance. The proposed method shows great promise for the industrial-scale synthesis of high-quality graphene with potential applications in future graphene-based devices, and furthermore, this method can be extended to exfoliate inorganic layered materials such as BN and MoS2.

Abstract:

In this study, we propose a novel approach to prepare few-layer graphene (FLG) dispersions, which is realized by exfoliating natural graphite flakes in a surfactant aqueous solution under hydrothermal treatment and liquid-phase exfoliation. In order to obtain stable and well-dispersed FLG dispersions, pristine graphite is hydrothermally expanded in a hexadecyltrimethylammonium bromide (CTAB) aqueous solution at 180 °C for 15 h, followed by sonication up to 3 h. In comparison to long-time sonication methods, the present method is significantly efficient, and most importantly, does not involve the use of an oxidizing agent and hazardous media, which will make it more competent in the scalable production of graphene.

Abstract:

Although graphene has been produced by various methods at lab scale, however, its cost effective mass production method is still a challenge. Graphene has been produced by liquid phase exfoliation, which is the most probable method for commercial production of graphene for various industrial applications.This paper reports high concentration production of few-layer graphene in DMSO (dimethyl sulfoxide) as solvent through liquid phase exfoliation assisted with sonication. The temperature was kept below 30oC. SEM, AFM, and XRD were used to characterize the produced graphene. SEM results confirm the production of few-layer graphene. EDX analysis shows that the graphene surface is free from oxides and impurities. AFM results also confirm the production of few-layer graphene. The UV-visible spectrophotometer was used to determine the concentration of the produced graphene, and the investigations demonstrate that the graphene production was increased by increasing the sonication time. There exist a linear relationship between the amount of produced graphene and sonication time for supplying energy during sonication.

Abstract:

Few-layer graphene sheets were synthesis using LPE with ultrasonic-assisted. The pristine graphite is directly exfoliated in deionized water with small addition of NH3 solution. In this study, we will investigate the relationship between concentration of NH3 solution corresponds to the graphene yield. The concentration of the NH3 solution varies from 18% to 26%. NH3 solution plays an important role as a medium to peel of graphite in the exfoliation process to form few-layer graphene sheets. The structural properties of the few-layer graphene sheets were examined using XRD, Raman Analysis, Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM) followed by UV-Vis Spectroscopy for its optical properties. The finest of few-layer graphene sheets was produced at 26% of NH3 concentration. This optimization results in a few layers of graphene sheets that may be used in the fields of nanoelectronics and optoelectronics.

Abstract:

Few-layer transition metal chloride graphene intercalation compounds have becJI fabricated by the mechanical exfoliation of graphite intercalation compounds (GTCs) containing CoC12 , NiCh, CuCl2 , MnCh and FeC13 . The number of graphene layers and the distribution of the intercalate in the few-layer graphene intercalation compounds (FLGICs) have been characterised using the optical contrast of the FLGICs against the Si02 substrate and the G-peak of the Raman spectrum. FLGICs containing CL single intercalate layer surrounded by two graphene layers have been fabricated and characterised, which are an ideal system to study 2D magnetic phase transitions.

Abstract:

This doctoral thesis is about the use of graphene for microwave tunable passive components. It opens a new paradigm in the use of innovative and cost-effective methods for producing tunable microwave components based on graphene. Specifically, it paves the way for future key components of microwave and wireless communication systems such as attenuators, phase shifters and antennas. A review of the state-of-the-art microwave passive components based on graphene in terahertz and microwaves is also provided. The integration of a number of components on a transmitter receiver system requires functional materials of nanometric scale. The use of innovative nanomaterials for designing state of the art microwave components is not new. The signature property of monolayer graphene that can be exploited for tunable microwave components is its electronically tunable resistance. This property is valid for dimensions as large as mm/cm to as small as micro and nanometers keeping a constant aspect ratio. The big challenge in research on future communication systems is to cost effectively design, implement and measure such proposed components. To this aim, in this thesis few layer graphene is deployed in the design of tunable attenuators, phase shifter and antenna. The advantage of using FLG is its cost effectiveness, technological simplicity and eco friendliness unlike most nanomaterials. A new design of tunable graphene attenuator was proposed based on shunt grounded vias connected to FLG flakes and a microstrip line. The grounded vias were symmetrically placed on each side of the microstrip line with two ports. The design, even though of not very high structural complexity resulted in superior functionality both in terms of dynamic range of insertion loss and the reflective insertion loss. The number of vias were then increased for improved functionality. With the increase in the number of vias, emerging structural parameters were optimized for higher insertion loss and improved mismatch. Simulations were performed for the optimization while fabrication of prototype and measurements were performed which were in good agreement to the simulated results. For the final case of eight vias connected to FLG, a total of more than 65 dB insertion loss was measured with reflective insertion loss as low as 2dB. Phase Shifter being a vital component of a communication system was also made incorporating FLG flakes. The tunable FLG resistance was converted to tunable reactance by the help of a stub composed of tapered line connected to FLG and a shorted stub. The various lengths and widths of the line were optimized so as to provide maximum shift in reactance when the change in FLG resistance would occur by an applied DC bias voltage. Subsequently, the optimized stub with variable reactance was connected to a two-port 50 Ω transmission line, the transmission on which would cause a phase shift by an applied DC voltage across the FLG. The maximum phase shift obtained was 43 degree with an additional insertion loss of 3 dB. The concept can be applied to a number of such units connected in cascade since the insertion loss is not very high. A combination of the phase shifter and attenuator can be used in the design of a tunable modulator based on a combination of amplitude and phase variation. The concept of the phase shifter was applied to a frequency reconfigurable patch antenna. FLG accompanied by a shorted stub optimized for maximum reactance change were deployed in a microstrip antenna. A total shift in the radiating frequency of 450 MHz was measured at an applied DC bias voltage of 5V with limited gain degradation.

Abstract:

In last decade, “Nanofillers” have been explored extensively in rubber compounds to improve dynamic-mechanical properties. Three classes of nanofillers: Clay minerals, Carbon nanoTubes and Graphitic nanofillers have been often used. Most recently, an attention towards “graphene” as nanofiller was reported due to its exceptional mechanical, thermal and electrical properties. In present Ph.D. thesis, different types of commercially available “few layer graphene” were explored in both apolar and polar diene rubbers. These nanofillers were dispersed with melt mixing technique which is most suitable technology for industrial applications, such as for tires. Structural-morphological characteristics of the nanofillers were made with SEM, TEM, XRD and static adsorption isotherms. Features such as shape anisotropy, number of graphene layers in a stack, BET surface area, surface activity and porosity of nanofillers were obtained. Optical microscopy was employed to obtain filler dispersion index and estimation of filler’s aggregates, agglomerates. Dynamic mechanical properties of the rubber compounds were made with rheometric curves for scorch and curing time, rheological properties through RPA (strain sweep and frequency sweep) for viscoelastic properties and filler networking, stress-strain for tensile strength and multi-hysteresis cycles for energy dissipation, dynamic mechanical thermal analysis for high and low temperature properties, hardness of compound for processing features and tear strength tests for compound durability. The electrical properties of rubber compounds were investigated via dielectric AC conductivity and permittivity tests. Epoxidation of diene rubbers (low rate, <10%) was obtained to investigate the effects of presence of epoxy functional groups along polymer chains on filler networking, polymer-filler interactions, filler dispersion and dynamic mechanical properties of rubber compounds. Quantitative analysis of epoxidation, rate of epoxidation and its influence on rubber matrix (such as change in glass transition temperature) was investigated through 1NMR and DSC tests. Under multi-hysteresis stress-strain cycles, it was found that a stable filler networking can reduce hysteresis losses.

Abstract:

Few-layer graphene sheets were produced from graphite oxide (GO) chemical and thermal reduction. For the chemical reduction of GO as reducing agents were used hydrazine hydrate, hydroxylammonium chloride, sodium borohydride and sodium sulfite. The reduced material was characterized by elemental analysis, thermo-gravimetric analysis, scanning electron microscopy, X-ray diffraction, Fourier transform infrared and Raman spectroscopy. A comparison of the deoxygenation efficiency of graphene oxide suspension by different method or reductants has been made, revealing that the highest degree of reduction was achieved by thermal reduction and using hydrazine hydrate and hydroxylammonium chloride as a reducing agents.

Abstract:

This thesis reports, for the ﬁrst time, measurements of optical properties of graphene as a function of layer number up to 700 layers. Optical reﬂection, optical transmission and atomic force microscopy was performed on graphene exfoliated on glass. Universal optical conductance of graphene arising from pi−pi^* interband transitions was used to identify and count up to 9 layer graphene samples with optical reﬂection microscopy alone. The optical properties of graphene are best described by refractive index of 1.88−1.59i at 550 nm up to 90 layers. For thicker graphene ﬂakes, we present a model for calculating conductance due to sigma−sigma^* transitions. Incorporating both transitions, we ﬁnd a refractive index of 2.70−1.11i at 550 nm, which shows good agreement to 250−700 layer graphene ﬂakes.
Cette thèse rapporte, pour la première fois, des mesures des propriétés optiques du graphene en fonction du nombre de couches et ce allant jusqu'à 700 couches. La réflexion et la transmission optique ainsi que la microscopie par force atomique ont été utilisés sur du graphene déposé sur de la vitre. La conductance optique universelle du graphene provenant des transitions entre les bandes pi-pi^* a été utilisée afin de compter jusqu'à 9 couches de graphene avec seulement la microscopie à réflexion optique. Les propriétés optiques du graphene sont bien décrites par un index de réfraction de 1.88-1.59i à 550 nm et ce jusqu'à 90 couches. Pour des échantillons plus épais, nous présentons un modèle servant à calculer la conductance causée par les transitions entre les bandes sigma-sigma^*. En incorporant les deux transitions, nous trouvons un index de 2.70-1.11i à 550 nm, ce qui démontre un bon accord avec les échantillons de graphene de 250-700 couches.

Single layer graphene is a nearly transparent two-dimensional honeycomb sp2 hybridized carbon lattice, and has received immense attention for its potential application in next-generation electronic devices, composite materials, and energy storage devices. This attention is a result of its desirable and intriguing electrical, mechanical, and chemical properties. However, mass production of high-quality, solution-processable graphene via a simple low-cost method remains a major challenge. Recently, electrochemical exfoliation of graphite has attracted attention as an easy, fast, and environmentally friendly approach to the production of high-quality graphene. This route solution phase approach complements the original micromechanical cleavage production of high quality graphite samples and also involved a chemically activated intermediate state that facilitates functionalization. In this thesis we demonstrate a highly efficient electrochemical exfoliation of graphite in organic solvent containing tetraalkylammonium salts, avoiding oxidation of graphene and the associated defect generation encountered with the broadly used Hummer's method. The expansion and charging of the graphite by intercalation of cations facilitates the functionalization of the graphene basal surfaces. Electrochemically enhanced diazonium functionalization of the expanded graphite was performed. The exfoliated graphene platelets were analyzed by Raman spectroscopy, to quantify defect states and the degree of exfoliation. Additional microscopy techniques provided additional insight into the chemical state and structure of the graphene sheets.

Abstract:

We characterized the thermoacoustic and photoacoustic properties of large-area, few-layer graphene by pulsed microwave and optical excitations. Due to its high electric conductivity and low heat capacity per unit area, graphene lends itself to excellent microwave and optical energy absorption and acoustic signal emanation due to the thermoacoustic effect. When exposed to pulsed microwave or optical radiation, distinct thermoacoustic and photoacoustic signals generated by the few-layer graphene are obtained due to microwave and laser absorption of the graphene, respectively. Clear thermoacoustic and photoacoustic images of large-area graphene sample are achieved. A numerical model is developed and the simulated results are in good accordance with the measured ones. This characterization work may find applications in ultrasound generator and detectors for microwave and optical radiation. It may also become an alternative characterization approach for graphene and other types of two-dimensional materials. (C) 2016 AIP Publishing LLC.

Abstract:

Using the linearized Boltzmann transport equation and perturbation theory, we analyze the reduction in the intrinsic thermal conductivity of few-layer graphene sheets accounting for all possible three-phonon scattering events. Even with weak coupling between layers, a significant reduction in the thermal conductivity of the out-of-plane acoustic modes is apparent. The main effect of this weak coupling is to open many new three-phonon scattering channels that are otherwise absent in graphene. The highly restrictive selection rule that leads to a high thermal conductivity of ZA phonons in single-layer graphene is only weakly broken with the addition of multiple layers, and ZA phonons still dominate thermal conductivity. We also find that the decrease in thermal conductivity is mainly caused by decreased contributions of the higher-order overtones of the fundamental out-of-plane acoustic mode. Moreover, the extent of reduction is largest when going from single to bilayer graphene and saturates for four layers. The results compare remarkably well over the entire temperature range with measurements of of graphene and graphite.
