Study on Confined Water in Flexible Graphene/GO Nanochannels.

The structural evolution of flexible nanochannels within a 2D material membrane, influenced by the ingress of water molecules, plays a crucial role in the membrane's filtration and structural stability. However, the experimental observation of nanoscale water is challenging, and current studies mostly focus on rigid nanochannels. Further investigation on the nanoconfined water is urgently needed, considering the flexibility and deformation of the channel. In this work, MD simulations and theoretical analyses are conducted to investigate the water structure and thermodynamic properties when confined within both rigid and flexible graphene/graphene oxide (GO) nanochannels. In free rigid graphene nanochannels, the interlayer distance exhibits a quantized increase with the number of water molecules, along with sudden changes in entropy, potential energy, and free energy of the water molecules. Meanwhile, in flexible graphene nanochannels, the average interlayer space increases linearly with the number of water molecules. In free rigid GO nanochannels, with the increase of oxidation concentration, the quantized increase in the interlayer space gradually diminishes, accompanied by a decrease in both potential energy and free energy. This work provides insights into the configurational evolution of flexible nanochannels within water, offering guidance in fields such as desalination and mass transport of 2D material membranes.

Effect of temperature on interface debonding behavior of graphene/graphene-oxide on cement-based composites

Temperature effect easily affect the adhesion of graphene/graphene oxide (GO) on the cement-based composites originating from the weaker non-covalent bonding at the interface, leading to weakening of the cementitious composite properties. In this study, the interfacial debonding behavior of graphene/GO and cement-based composites was investigated for low to high temperatures (250∼550 K) using controlled molecular dynamics simulations. The maximum tensile force and work of adhesion both decrease with increasing temperature, and the value of GO is 5∼6 times that of graphene. Especially at the high temperature end, GO is still difficult to peel off (Fmax: 7.93×103 pN, Wmax:2129.60 Kcal/mol). Meanwhile, the insights into the distribution and concentration of functional groups have shown that high concentrations and edge functional groups can improve interface adhesion. Energy decomposition demonstrated that, compared to the Coulomb effect of charge and the prestress of surface wrinkles, the van der Waals effect plays a major role in interface adhesion. Entropy analysis further reveals the high temperature sensitivity of graphene and the low sensitivity of GO due to edge functional groups. We believe that the insight into the temperature effect of interface debonding behavior at nanoscale can provide theoretical support for the effective temperature working conditions of graphene/graphene-oxide on cement-based composites.

Potassium citrate mediated self-restacking of graphene oxide to highly-microporous carbon nanosheets for high-performances supercapacitor

Because of the superior hydrophilicity of graphene oxide (GO) originated from its rich oxygenic species, assembly of graphene GO to a porous carbons have long been a hot-topic, however, most of them focus on preventing the occurrence of restacking of GO so that an open-accessed nanostructure could be attained. Herein, at a just the opposite way, we developed a strategy using potassium citrate mediated evaporation induced self-restacking of GO to fabricate porous carbon nanosheets. The resultant products (PCG-x) owns a nanosheet morphology, richness in microporosity, abundant oxygenic functionalites (8.96–9.49 atom%), moderate surface area (683–833 m2/g) and high packing density. Systematically electrochemical investigation show that the resultant PCG-n fabricated with optimal potassium citrate/GO ratio based electrode and devices attains superior both gravimetric and volumetric supercapacitor performances to its counterparts of rGO and PCG based ones due to the features of high microporosity ratio, moderate oxygenic functionalities and high packing density. Concerning PCG-n based device, a considerable energy density of 33 Wh/kg@900 W/kg (34.7 Wh/L@945 W/L) was achieved, the value is higher than that of rGO, PCG and some recently reported carbon based supercapacitors, offering great potential for energy storage.

Selective Growth of MAPbBr3 Rounded Microcrystals on Micro-Patterned Single-Layer Graphene Oxide/Graphene Platforms with Enhanced Photo-Stability.

The synergistic combination of hybrid perovskites with graphene-related materials is leading to optoelectronic devices with enhanced performance and stability. Still, taking advantage of the solution processing of perovskite onto graphene is especially challenging. Here, MAPbBr3 perovskite is grown on single-layer graphene/graphene oxide (Gr/GO) patterns with 120 µm periodicity using a solution-processed method. MAPbBr3 rounded crystals are formed with sizes ranging from nanometers to microns, either forming continuous films or dispersed particles. A detailed morphological and structural study reveals a fully oriented perovskite and very different growth habits on the Gr/GO micro-patterns, which we relate to the substrate characteristics and the nucleation rate. A simple method for controlling the nucleation rate is proposed based on the concentration of the precursor solution and the number of deposited perovskite layers. The photoluminescence is analyzed in terms of the crystal size, strain, and structural changes observed. Notably, the growth on top of Gr/GO leads to a huge photostability of the MAPbBr3 compared with that on glass. Especially outstanding is that of the microcrystals, which endure light densities as high as 130 kW/cm2. These results allow for anticipating the design of integrated nanostructures and nanoengineered devices by growing high-stability perovskite directly on Gr/GO substrates.

Phase regeneration of star-16QAM using phase-sensitive amplification in graphene silicon-based organic hybrid waveguide

We theoretically demonstrate the phase regeneration of the star-16-quadrature-amplitude-modulation(star-16QAM) signal in a graphene-graphene oxide hybrid waveguide. The multi-order dispersion properties of this waveguide are tuned by graphene, where the near-zero-dispersion-point moves to right with increasing applied electrochemistry. The waveguide nonlinearity coefficient is 1.534×106/m/W and the dispersion is flat in the ultra-wide wavelength range of 1310 nm to 1860 nm by filling the waveguide with the high kerr coefficient organic material graphene oxide. The phase regeneration of the star-16QAM signal is achieved by using a dual-conjugate-pump degenerate four-wave mixing (FWM) technique, and the results show that the error-vector -magnitude (EVM) is reduced from 39.25% to 2.14%, the phase noise is effectively compressed.

Sensitive label-free detection of the biomarker phosphorylated tau−217 protein in Alzheimer's disease using a graphene-based solution-gated field effect transistor

Alzheimer's disease (AD) is generally diagnosed using advanced imaging, but recent research suggests early screening using biomarkers in peripheral blood is feasible; among them, plasma tau proteins phosphorylated at threonine 231, threonine 181, and threonine 217 (p-tau217) are potential targets. A recent study indicates that the p-tau217 protein is the most efficacious biomarker. However, a clinical study found a pg/ml threshold for AD screening beyond standard detection methods. A biosensor with high sensitivity and specificity p-tau217 detection has not yet been reported. In this study, we developed a label-free solution-gated field effect transistor (SGFET)-based biosensor featuring a graphene oxide/graphene (GO/G) layered composite. The top layer of bilayer graphene grown using chemical vapor deposition was functionalized with oxidative groups serving as active sites for forming covalent bonds with the biorecognition element (antibodies); the bottom G could act as a transducer to respond to the attachment of the target analytes onto the top GO conjugated with the biorecognition element via π−π interactions between the GO and G layers. With this unique atomically layered G composite, we obtained a good linear electrical response in the Dirac point shift to p-tau217 protein concentrations in the range of 10 fg/ml to 100 pg/ml. The biosensor exhibited a high sensitivity of 18.6 mV/decade with a high linearity of 0.991 in phosphate-buffered saline (PBS); in human serum albumin, it showed approximately 90% of the sensitivity (16.7 mV/decade) in PBS, demonstrating high specificity. High stability of the biosensor was also displayed in this study.

A chemiresistive biosensor for detection of cancer biomarker in biological fluids using CVD-grown bilayer graphene.

A chemiresistive biosensor is described for simple and selective detection of miRNA-21. We developed chemical vapor deposition (CVD) and low-damage plasma treatment (LDPT)-treated bilayer graphene composite of graphene oxide/graphene (GO/GR) for the determination of a reliable biomarker. We have successfully overcome the self-limiting growth mechanism by using CVD method to grow more than one layer of graphene on copper foil. In addition, LDPT can be used to form GO/GR structures for chemiresistive biosensor applications. Due to the direct formation of BLGR (bilayer graphene), the coupling between graphene layers is theoretically superior to that of stacked BLGR, which is also confirmed by the blue shift of the characteristic peak of graphene in Raman spectroscopy. The shift is about double compared with that of stacked BLGR. Based on the results, the limit of detection for the target miRNA-21 was calculated to be 5.20 fM and detection rage is calculated as 100 fM to 10 nM, which is obviously better performance. Compared with previous work, this chemiresistive biosensor has good selectivity, and stability towards detection of miRNA-21. The ability to detect miRNA-21 in different biological fluids was almost identical to that in pH 7.4 phosphate-buffered saline (PBS). Thus, the proposed bilayer GO/GR of modified chemiresistive biosensor may potentially be applied to detect cancer cells in clinical examinations.Graphical abstract Supplementary InformationThe online version contains supplementary material available at 10.1007/s00604-022-05463-7.

Approximately 1 nm-sized artificial tunnels in wrinkled graphene-graphene oxide composite membranes for efficient dye/dye separation and dye desalination

Efficient separation of solutes by nanofiltration membranes (NMs) is the key to the utilization of wastewater and sustainable economic development. However, the establishment of dense and narrow-dispersed artificial tunnels in NMs remains a challenge, leading to impractical water permeability and solutes selectivity for real-world applications. In this work, we construct approximately 1 nm-sized artificial tunnels within the GO-based membranes (GOMs) to balance the water permeation and nanofiltration performances, by intercalating the three-dimensional wrinkled graphene (WG) sheets with surface functional groups manipulated. Such peculiar nanotunneled structure in the WG/GO composite membrane, at the optimized WG/GO ratio of 1:2, is revealed by the selective filtration of large-sized PEG gel particles over sub-nm-sized counterparts, leading to a selective rejection of >1 nm-sized molecules (e.g. CV, CR, and TB) over sub-nm-sized impurities (e.g. NR, MB, NaCl, and Na2SO4) with excellent mechanical stability and anti-fouling property. More importantly, the dense nanotunneled structure enables the composite membrane with an increased water flux of 65.68 L m-2h−1 bar−1, which is ∼48 times enhanced compared to that of pure GOM. Our strategy enables the precise engineering of artificial nanotunnels within compact GOM for high-performance dye/dye separation and dye desalination applications.

Molecular dynamics simulation of the adsorption properties of graphene oxide/graphene composite for alkali metal ions

As one of the effective methods to remove heavy metals, graphene (G) composite adsorption technology is irreplaceable in water pollution control and water purification, but its adsorption mechanism is not clear. Materials Studio (MS) software was used to simulate the molecular dynamics of the interaction between graphene oxide/graphene (GO/G) composite and alkali metal ion (M+). Based on the calculation of the interaction energy, diffusion coefficient and radial distribution function (RDF), The adsorption law of GO/G on M+ was investigated and its mechanism was revealed. It provides a theoretical basis for the research and development of the adsorption performance of G composite electrode. The calculated results show that the interaction energy between different M+ and GO/G is negative, indicating that the interaction between them is mutual attraction. The energy of GO/G composites and the total energy of M+-GO/G increase with the increase of M+ radius. The larger the hydrated ion radius of M+ is, the larger the diffusion coefficient is. Cs+ diffusion coefficient is slightly lower than rubidium. According to RDF analysis, M+-GO and M+ − O (GO) both have bonding within 3.5 Å and non-bonding after 3.5 Å, and the non-bonding interaction of M+-GO is greater. However, the bonding interaction between M+-O(GO) is larger than the non-bonding interaction, indicating that there are bonding and non-bonding interactions in the system when GO/G composite adsorb M+. The interaction between M+ and GO surface is mainly provided by non-bonding interaction, while the interaction between M+ and O atoms of GO surface is mainly provided by bonding interaction.

Graphene oxide-graphene Van der Waals heterostructure transistor biosensor for SARS-CoV-2 protein detection.

The current outbreaking of the coronavirus SARS-CoV-2 pandemic threatens global health and has caused serious concern. Currently there is no specific drug against SARS-CoV-2, therefore, a fast and accurate diagnosis method is an urgent need for the diagnosis, timely treatment and infection control of COVID-19 pandemic. In this work, we developed a field effect transistor (FET) biosensor based on graphene oxide-graphene (GO/Gr) van der Waals heterostructure for selective and ultrasensitive SARS-CoV-2 proteins detection. The GO/Gr van der Waals heterostructure was in-situ formed in the microfluidic channel through π-π stacking. The developed biosensor is capable of SARS-CoV-2 proteins detection within 20 min in the large dynamic range from 10 fg/mL to 100 pg/mL with the limit of detection of as low as ∼8 fg/mL, which shows ∼3 × sensitivity enhancement compared with Gr-FET biosensor. The performance enhancement mechanism was studied based on the transistor-based biosensing theory and experimental results, which is mainly attributed to the enhanced SARS-CoV-2 capture antibody immobilization density due to the introduction of the GO layer on the graphene surface. The spiked SARS-CoV-2 protein samples in throat swab buffer solution were tested to confirm the practical application of the biosensor for SARS-CoV-2 proteins detection. The results indicated that the developed GO/Gr van der Waals heterostructure FET biosensor has strong selectivity and high sensitivity, providing a potential method for SARS-CoV-2 fast and accurate detection.

Electrochemical sensors for sulfamethoxazole detection based on graphene oxide/graphene layered composite on indium tin oxide substrate

BackgroundSulfamethoxazole (SMX) can produce many side effects in the human body and several hematological abnormalities. Therefore, the analytical determination of SMX in pharmaceutical formulations and biological fluids is essential. MethodsA biocompatible composite of graphene oxide/graphene (GO/G) layered structure was synthesized to develop electrochemical biosensors for SMX detection. Two layers of single-layer graphene grown by chemical vapor deposition were stacked and annealed to form bilayer graphene (BLG). The BLG was modified by a low-damage plasma treatment—atomic layer oxidation. The top graphene layer was modified to graphene oxide, while the bottom graphene layer was conserved to safeguard its conductive properties and form a layered composite on an indium tin oxide (ITO) substrate. Significant findingsThe GO/G layered composite on the ITO glass substrate, plasma-treated for 15 min exhibited optimized redox properties, with a relatively low charge-transfer resistance. At pH 6, the relationship between the oxidation peak current and the SMX concentration (0.1–50 μM) was linear with a sensitivity of 0.262 μA/μM. With the addition of cetylpyridinium chloride, the sensing performance of the GO/G-based electrochemical sensor was ameliorated to 0.529 μA/μM. The GO/G electrode also exhibited high selectivity and stability to SMX.

Role of hydrogen bonds in thermal conductance at the graphene oxide-H2O interface

Interfacial water has been estimated to mediate the thermal coupling at the interface between biological tissues and graphene/graphene oxide (GO)-based bio-nano devices, while the interfacial energy transfer is limited by the extreme thermal resistance between graphene and water due to the inherent vibration mismatch and the weak interaction. Oxygen-containing functional groups on the surface of GO form hydrogen bonds (H-bonds) with water, which enhances interfacial interaction and promotes thermal transport at the interface, thereby GO/water model is used to investigate the effects of H-bonds on the thermal boundary conductance (TBC). The results reveal that both the density and distribution of hydroxyl groups affect the interfacial H-bonds and further affect the thermal transport at interface. TBC increases initially with the increased H-bond density and then reaches a plateau when H-bond density reaches saturation. The homogeneously distributed hydroxyl groups form more H-bonds with water molecules than the clustered pattern, and results in more efficient interfacial thermal transfer. The variation of TBC with oxidation concentration can be explained by the mass density depletion length and the density of interfacial H-bonds. Our study highlighted the key role of H-bonds in regulating interfacial thermal transfer and provides theoretical basis and guiding methodology for thermal dissipation of graphene and GO-based bioelectronic devices.

Effect of Pulsed Light Irradiation on Patterning of Reduction Graphene Oxide-Graphene Oxide Interconnects for Power Devices

Reduction graphene oxide (r-GO) lines on graphene oxide (GO) films can be prepared by a photocatalytic reduction and photothermal reduction method. A mechanism of partial GO reduction by pulsed photon energy is identified for preparing patterned rGO-GO films. The photocatalytic reduction method efficiently reduces GO at low photon energies. The successful production of a patterned rGO-GO film without damage by the photo thermal reduction method is possible when an energy density of 6.0 or 6.5 J/m2 per pulse is applied to a thin GO film (thickness: 0.45 μm). The lowest resistance obtained for a photo-reduced rGO line is 0.9 kΩ sq−1. The GO-TiO2 pattern fabricated on the 0.23 μm GO-TiO2 composite sheet through the energy density of each pulse is 5.5 J/m2 for three pulses.

Graphite Foil Waste to Graphene: New Carbon Precursors for Synthesis of Graphene and its Oxides

In this paper, graphene oxide (GO) was obtained by oxidation of powdered graphite foil wastes (pGFW) at 0 - 40°C. Oxidizing reagents can easily penetrate the layers of graphite foil and thus, the intercalation or functionalization-oxidation processes may occur resulting in graphite oxide formation. The methods of synthesis of GO and its separation from the reaction mixture were partially corrected. GO was reduced, also, to the reduced graphene oxide (rGO) by using hydroiodic acid, ascorbic acid, zinc powder, hydrazine, and Alnus extract. Thermal treatment of GO powders and GO films, obtained from pGFW was implemented at 20-300° C in air and at 20-1000° C under argon flow and in a vacuum. At high-temperature treatment (1000°C) of GO graphene was obtained with a defective structure.

P-TiO2/GO heterojunction based VOC sensors: A new approach to amplify sensitivity in FET structure at optimized gate voltage

Graphene/graphene oxide (GO) field effect transistor (FET) is widely investigated for the mainstream electronics. On the other hand, GO and TiO2 nanocomposite is extensively reported for sensing and energy applications. In the current study, we developed p-type TiO2/GO hybrid channel based back gated FET sensors for the detection of volatile organic compounds (VOCs) of very low concentrations. High sensitivity at low concentration of VOC was achieved by high surface reactivity towards VOC by p-TiO2/GO heterojunctions and limited drain current at appropriate gate voltage near Dirac point. Ambipolar transport due to field effect is only observed in GO dominated nanocomposites where 1 vol% p-TiO2 and 99 vol% GO based FET exhibits best performance having 115% response in 100 ppm ethanol at 100 °C with VDS = 0.5 V, VGS = 0.7 V. The response is enlarged ~ 34 times at VGS = 0.7 V as compared to the VGS = 0 V extending the lower detection limit of ethanol up to 500 ppb.

E-Graphene: A Computational Platform for the Prediction of Graphene-Based Drug Delivery System by Quantum Genetic Algorithm and Cascade Protocol.

Graphene, as a novel category of carbon nanomaterials, has attracted a great attention in the field of drug delivery. Due to its large dual surface area, graphene can efficiently load drug molecules with high capacity via non-covalent interaction without chemical modification of the drugs. Hence, it ignites prevalent interests in developing a new graphene/graphene oxide (GO)-based drug delivery system (GDDS). However, current design of GDDS primarily depends on the prior experimental experience with the trial-and-error method. Thus, it is more appealing to theoretically predict possible GDDS candidates before experiments. Toward this end, we propose to fuse quantum genetic algorithm (QGA) and quantum mechanics (QM)/semi-empirical quantum mechanics (SQM)/force field (FF) to globally search the optimal binding interaction between the graphene/GO and drug in a given GDDS and develop a free computational platform “e-Graphene” to automatically predict/screen potential GDDS candidates. To make this platform more pragmatic for the rapid yet relatively accurate prediction, we further propose a cascade protocol via firstly conducting a fast QGA/FF calculation with fine QGA parameters and automatically passing the best chromosomes from QGA/FF to initialize a higher level QGA/SQM or QGA/QM calculation with coarse QGA parameters (e.g., small populations and short evolution generations). By harnessing this platform and protocol, systematic tests on a typical GDDS containing an anticancer drug SN38 illustrate that high fabrication rates of hydroxyl, epoxy, and carboxyl groups on a pristine graphene model will compromise the stability of GDDS, implying that an appropriate functionalization rate is crucial for the delicate balance between the stability and solubility/biocompatibility of GDDS. Moreover, automatic GDDS screen in the DrugBank database is performed and elicits four potential GDDS candidates with enhanced stability than the commonly tested GDDS containing SN38 from the computational point of view. We hope that this work can provide a useful program and protocol for experimental scientists to rationally design/screen promising GDDS candidates prior to experimental tests.

Interaction of double-stranded polynucleotide poly(A:U) with graphene/graphene oxide.

Hybrids formed by DNA/RNA and graphene family nanomaterials are considered as potentially useful multifunctional agents in biosensing and nanomedicine. In this work, we study the noncovalent interaction between double-stranded (ds) RNA, polyadenylic:polyuridylic acids (poly(A:U)) and graphene oxide/graphene (GO/Gr) using UV absorption spectroscopy and molecular dynamics (MD) simulations. RNA melting showed that relatively long ds-RNA is adsorbed onto GO (at an ionic strength of [Formula: see text]) at that a large fraction of RNA maintains the duplex structure. It was revealed that this fraction decreases over long time (during a few days), indicating a slow adsorption process of the long polymer. MD simulations showed that the adsorption of duplex (rA)[Formula: see text]: (rU)[Formula: see text] or (rA)[Formula: see text]: (rU)[Formula: see text] on graphene starts with the interaction between [Formula: see text]-systems of graphene and base pairs located at a duplex tail. In contrast to relatively long duplex (rA)[Formula: see text]: (rU)[Formula: see text] which keeps parallel arrangement along the graphene surface, the shorter one ((rA)[Formula: see text]: (rU)[Formula: see text]) always adopts a perpendicular orientation relative to graphene even in case of the initial parallel orientation. It was found out that (rA)[Formula: see text]: (rU)[Formula: see text] forms the stable hybrid with graphene keeping essential fraction of the duplex, while (rA)[Formula: see text]: (rU)[Formula: see text] demonstrates the duplex unzipping into two single strands with time. The interaction energies between adenine/uracil stacked with graphene as well between nucleotides in water environment were determined.

Poly(3,4-ethylenedioxythiophene): Poly(styrenesulfonate) coated three layer graphene-graphene oxide heterostructure for UV and IR detection

The present work emphasizes on the use of laser assisted reduction for the fabrication of freestanding three-layer graphene (3LG)-graphene oxide heterostructure (LRG). PEDOT:PSS due to its high spectral responsivity and electron blocking nature was deposited over LRG for better photon absorption, exciton generation and prevention of electron-hole recombination. Powder XRD and micro-Raman studies revealed the successful formation of LRG and PEDOT:PSS/LRG heterostructure. A superior photoresponse characteristics with an ultra-high gain exceeding 100%, responsivity and detectivity in the order of 102 AW−1 and 1010 Jones, respectively was observed under ultraviolet (365 nm) illumination for PEDOT:PSS/LRG. The superior performance was owed to the inhibition of charge carrier recombination by mid-gap state band in LRG. The fabricated films have a promising future in opto-electronic industry, sensing and environmental monitoring purposes.

Heterogeneous Ice Nucleation by Graphene Nanoparticles

Nanostructure, chemical composition and size distribution of aerosols have prime important effects on their efficiency in heterogeneous ice nucleation (HIN). The ice nucleation usually requires active sites in the aerosols in order to act as ice nuclei (IN). In this study, HIN and probable active sites of the graphene-graphene oxide nanoparticles (GGON), obtained from graphite oxide by low temperature thermal shock (LTTS), were investigated. Characteristics and size distribution of the GGON were identified using scanning electron microscope (SEM) and image processing of the results, Fourier transform infrared spectroscopy (FTIR), Raman spectra and X-ray diffraction (XRD) of their sheets. The FTIR spectra indicate stronger carbon-oxygen bonds in the samples obtained by LTTS. In addition, maximum size distribution of the GGON was ranged around 160–180 nm. After introducing these particles in the cloud chamber, HIN has occurred and ice crystals were formed. Size distribution of crystals were obtained from image processing of the plates, where covered by a thin layer of Formvar, showed the number of ice crystals in the GGON were increased as temperature increased from −20 °C to −10 °C. In addition, two possible mechanisms of asymmetry and deformation in ice crystals of the GGON were described.

Noncovalent interaction of single-walled carbon nanotubes with graphene/graphene oxide: Spectroscopy and theoretical characterizations

Abstract We present a study of noncovalent coupling of single-walled carbon nanotubes (SWNTs) with graphene/graphene oxide (GO) employing optical spectroscopy (UV–visible optical absorption, Raman spectroscopy), scanning microscopy, and theoretical calculations (molecular dynamics simulations, DFT calculations). The optical absorption of SWNT-GO aqueous solution reveals a transformation of bands corresponding to both SWNTs and GO that can be explained by the formation of nanohybrids of two systems. The spectra showed suppression of the intensities of the bands related to the electronic transitions between the first pair of Van Hove singularities in the electronic density of states of semiconducting SWNTs that was explained by the charge transfer from SWNTs to GO. The nanohybrids are not destroyed after deposition of SWNT-GO aqueous solution on a film. The analysis of Raman spectra of the SWNT-GO film reveals the charge transfer between the components. The strong coupling induces stress and causes structural deformations in the carbon nanostructures. The appearance of this effect is in good agreement with the performed calculations. This work provides new experimental and theoretical results on the energetics and structural characteristics of SWNT-GO nanohybrids which may be scientifically and practically significant as they can be used to elaborate solar cells, batteries, sensors, etc.
