The effect of graphene oxide content on the photocatalytic activity of (ZnCdS/MnFe2O4/GO) nanocomposite

Novel ternary Zinc cadmium sulfate/Manganese ferrite/Graphene oxide (ZnCdS/MnFe2O4/GO) nanocomposites were synthesized via a hydrothermal process in this study, with a focus on optimizing the graphene oxide (GO) content. Characterization techniques such as X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), UV–visible spectroscopy, photoluminescence (PL) spectroscopy, and N2 physisorption were employed. The investigation revealed that nanocomposites with 3 wt% GO content exhibited superior adsorption capacity and visible-light photocatalytic activity for the removal of Methylene blue (MB) from wastewater. The ZnCdS/MnFe2O4/GO 3 % composite demonstrated exceptional stability and efficiency, achieving nearly 96 % MB removal within 220 min. Moreover, the ZnCdS/MnFe2O4/GO 3 % nanocomposites displayed promising reusability with sustained photocatalytic activity over multiple degradation-regeneration cycles. These findings highlight the potential of ternary GO/ZnCdS/MnFe2O4 nanocomposites as effective photocatalysts for the practical remediation of organic pollutants in wastewater systems.

Effect of GO content on microstructure and mechanical properties of Ti6Al4V coating reinforced artificial joint.

In this study, we have innovatively proposed a method of in-situ synthesized TiC hard phase to improve the surface mechanical properties of artificial joint materials (Ti6Al4V). In order to explore the optimum graphene oxide (GO) addition, GO/Ti6Al4V composite powders with different proportions (0, 0.5, 1.0, and 1.5 wt.%) were prepared. The homogeneously dispersed GO/Ti6Al4V composite powder was prepared on Ti6Al4V substrate by laser cladding technology. The microstructure, phase composition, and mechanical behavior of GO/Ti6Al4V composite coatings were studied by scanning electron microscope (SEM), optical microscope (OM), energy dispersive spectrometer (EDS), tribometer, hardness tester, and surface profiler. The results showed that the addition of GO could significantly improve the mechanical properties of TC4 substrate. During the preparation of the coating, the grain size of in-situ TiC phase was nanoscale and was distributed between acicular martensite, which played a critical role in enhancing the mechanical properties of the coating. The TiC phase distributed between acicular martensite refine the grain size of phase and improve the cutting resistance of the coating. Nevertheless, excessive GO decreased the fluidity of the molten pool, and micro holes tended to generate in the coating, which had a negative impact on the mechanical properties of the coating. At the GO content of 0.5 wt.%, the microhardness of the GO/Ti6Al4V coating was 1.325 times that of pure Ti6Al4V. Under the friction environment of simulated body fluid solution, the average friction coefficient was approximately 0.307 and the wear rate decreased to 3.5 × 10-7 mm3/N · m.

Experimental and theoretical investigation of mechanical and rheological properties of compatibilized XNBR/NR/GO nanocomposites

In this research, nanocomposites based on carboxylated nitrile rubber (XNBR)/natural rubber (NR) with different concentrations of graphene oxide (GO) were prepared by melt mixing method. The role of XNBR-grafted maleic anhydride (XNBR-g-GMA) as a compatibilizer and the effect of GO content on the morphological, mechanical, rheological, and vulcanization properties were evaluated. It was observed that with increasing the concentration of GO, the scorch and vulcanization time decreased, while the torque of the samples increased. Morphological studies illustrated that by raising the concentration of GO in the presence of a compatibilizer, the fracture surface of nanocomposites became rougher and the average size of dispersed phase decreased. In addition, the presence of XNBR-g-GMA compatibilizer improved the uniform dispersion of GO within the XNBR/XNBR-g-GMA/NR matrix. The mechanical properties of nanocomposites showed the best results for XNBR/NR with a ratio of 75/25. Theoretical studies on the mechanical and rheological properties of nanocomposites performed by Mori-Tanaka and Carreau-Yasuda models and illustrated a good agreement with experimental data.

Strengthened corrosion control of biodegradable poly(trimethylene carbonate) coating on bioabsorbable Mg alloy by introducing graphene oxide

Corrosion control of bioabsorbable Mg alloy stents is an attractive topic in recent years. Biodegradable polymer modification is a potential anti-corrosion method, but cannot achieve the desired corrosion protection due to the high water permeability of biodegradable polymers. In this study, a strengthened corrosion control strategy is proposed: Graphene oxide (GO) was introduced into a poly(trimethylene carbonate) (PTMC) coating to improve its anti-corrosion performance. GO/PTMC composite coatings with different GO contents were applied to AZ31b Mg alloy surfaces, and the effect of GO content (0, 0.2, 1, 3, 6, and 10 wt%) on surface characteristics, corrosion resistance, and in vitro biosafety was investigated. The results showed that the increase of GO content in the PTMC coating (<6 wt%) could improve its corrosion resistance by prolonging the permeation path of solution. Meanwhile, the addition of GO (<6 wt%) had little negative effects on cytocompatibility and hemocompatibility. However, when the addition of GO exceeded 6 wt%, GO aggregated on the coating surface, resulting in the formation of new defects and a rapid decrease in corrosion resistance. The optimized sample (GO content: 6 wt%) had the highest impedance modulus of 8.9 × 107 Ω·cm2 at 0.1 Hz and good in vitro biocompatibility, which shows great potential for application in vascular stents.

Fabrication and characterization of graphene oxide and glass fiber‐based hybrid epoxy composites

AbstractThis work aims to develop and characterize graphene oxide (GO) and glass fiber (GF)‐based hybrid epoxy composites. Graphite oxide was synthesized by improved Hummers' method, and it was uniformly dispersed in ethanol by ultra‐sonication to form GO suspension. Later, GO and GF‐based hybrid epoxy composites were prepared by hand layup method followed by curing under compression to develop composite sheets accordingly to the ASTM standards (D3039 &amp; D6110‐18). Fourier transform infrared spectra of the neat and the GF‐based hybrid epoxy composites confirmed the formation of improved interface between GO/epoxy and silane coating present on GF surface, which is well validated with the given reaction schematic. Scanning electron microscope and elemental mapping results corroborate our point that the GO filled the voids and empty spaces and lessened the water absorption properties of the composite which is much needed for the application of composites at high altitudes and marine environment. Effect of GO content on mechanical properties of prepared composites was studied by varying the GO content from 0.1 to 1.2 wt%. Mechanical characterization of GO and GF‐based hybrid epoxy composites were carried out by tensile and impact testing. Ultimate tensile strength, impact strength and elongation were increased by ~20%, ~41%, and ~19%, respectively, at 0.4 wt% addition of composition. The avg. delamination factor for this composition (0.4 wt% of GO) reduced as compared to neat epoxy and other wt% compositions for 6‐, 5‐, 4‐, &amp; 3‐mm drill bit sizes.

La0.75Sr0.25Cr0.5Mn0.5O3/Graphene Oxide-Based Composite Electrodes for Energy Storage Applications

This study aims to produce La0.75Sr0.25Cr0.5Mn0.5O3 (LSCM)/graphene oxide (GO)-based composite electrode for energy storage applications. Perovskite was synthesized by solution combustion method. Graphene was synthesized by improved Hummers’ method. Synthesized active material was coated on porous Ni foam by vacuum centrifuge mixing. Effect of GO content on specific capacitance (Csp) of LSCM was studied by varying GO content from 1-7 wt. %. As synthesized perovskite and GO were characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy and Fourier transform infrared spectroscopy. Electrochemical characterization was carried out by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in 3 M KOH. Electrochemical characterization revealed that LSCM electrode showed maximum Csp of 751 Fg-1 at 1 mVs-1. By increasing GO content from 1 wt. % to 3 wt. % and 5 wt. %, Csp was increased to 930 Fg-1, 1137 Fg-1 and 1223 Fg-1 respectively. Further evaluation of CV results revealed that predominant charge storage mechanism of electrodes was Faradic in nature which exhibited distinct redox peaks. EIS revealed that LSCM-5%GO electrode showed lowest charge transfer resistance among other electrodes. Furthermore, LSCM-5%GO electrode showed 93 % charge retention after 3000 charge-discharge cycles.

Synergistic strengthening effect of titanium matrix composites reinforced by graphene oxide and carbon nanotubes

Titanium matrix composites reinforced by graphene oxide (GO) and carbon nanotube (CNT) were successfully prepared by hot-pressing sintering. The effect of GO content on dispersion and particle size of CNT was analysed. In addition, the microstructure, phase structure and mechanical properties of Ti/GO-CNT composites were characterized, and the synergistic strengthening mechanism was investigated. The results show that dispersion of CNT can be significantly improved by adding GO. TiC particles with size of 100–200 nm are formed in situ between matrix and reinforcements. CNT and GO still partly keep an integrated structure after sintering. A significant synergetic effect was observed between GO and CNT that improved the mechanical properties of the composite. The maximum hardness and yield strength of the composite were 771.5 HV and 1387.1 MPa, which is 150% and 74% higher than that of pure Ti when the GO/CNT ratio is 5:1. The synergistic strength enhancement reaches a maximum when GO/CNT ratio is 1:1.

Effect of graphene oxide content on morphology and topography of polysulfone‐based mixed matrix membrane for permeability and selectivity of carbon dioxide and methane

AbstractIn this work, mixed matrix membranes based on polysulfone containing different contents of graphene oxide were prepared using a phase inversion process. The morphological, and structural properties as well as surface features of the samples were investigated by means of field‐emission scanning electron microscopy, infrared and x‐ray diffraction spectroscopies, as well as atomic force microscopy. The gas permeation/selectivity behavior of graphene oxide‐loaded polysulfone samples was studied using pure carbon dioxide, and methane. Morphological images depicted that the addition of graphene oxide to polysulfone in the presence of isopropyl alcohol as non‐solvent was reduced the numbers of finger‐like macro‐voids, and caused to the formation of teardrop‐like structures. Besides the x‐ray patterns and Fourier transform infrared spectra confirmed the graphene oxide nano‐plates and polysulfone with no chemical interactions, the atomic force microscopic patterns demonstrated a decrease in the average roughness of samples’ surface from 21.85 nm for plain polysulfone membrane to 5.02 nm for ones containing 2 weight percentages of graphene oxide as the optimum sample. Finally, a significant enhancement for the selectivity of carbon dioxide/methane with the value of 38.08 has been observed by the sample which was approximately 22‐fold more than that of plain polysulfone.

Effect of graphene oxide content on the tensile properties and swelling ratio of chitosan/xanthan gum/graphene oxide hydrogel films

In this study, chitosan (CS)/xanthan gum (XA)/graphene oxide (GO) nanocomposite hydrogels were prepared to enhance mechanical properties of CS/XA hydrogels. The hydrogels were characterized by Fourier-transform infrared spectroscopy (FT-IR) spectra, wide-angle X-ray diffraction (WXAD) patterns, thermogravimetric analysis, and universal testing machine. The swelling ratio of dried CS/XA and CS/XA/GO films were also measured in deionized water at 37 °C. The effect of GO content on the tensile properties and swelling ratio of CS/XA/GO hydrogel films were investigated. With addition of GO, tensile strength and modulus of CS/XA hydrogel films were improved without significant decrease of elongation at break, while the swelling ratio of CS/XA/GO films decreased with increasing GO contents.

Thermal, Mechanical Properties and Rheological Behavior of Poly(Propylene Carbonate)/Poly(Ethylene Glycol)/Graphene Oxide Nanocomposites

Graphene oxide (GO) is an efficient nanofiller for polymers and a good dispersion of GO in polymer matrix is most important to enhance properties. Poly(propylene carbonate) (PPC)/GO nanocomposite was prepared by a method with solution blending and melt mixing for improvement of GO dispersion. First, GO was prepared using an improved Hummers method. In the solution blending, GO was well dispersed in water and another low molecular weight polymer, poly(ethylene glycol) (PEG), was also dispersed in water, as a dispersion medium for next melt mixing of PPC and GO. Then PPC and PEG/GO was melt-mixed in a HAAKE mixer. The dispersion of GO in PPC matrix and effect of GO content on properties of PPC/PEG/GO nanocomposites was investigated. Results show that tensile strength of nanocomposites with the content of 0.5 wt% GO increased from 17.51 MPa (pure PPC) to 21.61 MPa and elongation at break can be kept high. The complex viscosity, storage and loss modulus is the highest for nanocomposites with the content of 0.5 wt% GO. This illustrated that a lower content of GO can improve the properties of PPC, owing to the good dispersion of GO in PPC matrix. Based on dispersion of GO and chemical structure of PPC, PEG, and GO, the reinforcement mechanism of GO in PPC was analyzed.

Preparation and Characterization of Grafted Natural Rubber/Graphene Oxide Nanocomposites

Vinyltriethoxysilane (VTES) was grafted onto natural rubber (NR) in latex form, using potassium persulfate (KPS) as initiator. The VTES grafted NR (NR-g-VTES) was then further reinforced with graphene oxide (GO) by a mechanical mixing method with different GO loadings to get the rubber composite (GO/NR-g-VTES). The NR-g-VTES was characterized and confirmed by attenuated total teflectance-Fourier transforms infrared spectroscopy (ATR-FTIR). The effect of GO content on the curing characteristics and resulting mechanical properties of the GO/NR-g-VTES were studied and compared with neat NR filled with GO (NR/GO). The maximum and minimum torque and the tensile and tear strength of the NR-g-VTES/GO composites were higher than that of NR/GO. The samples containing low GO concentration showed maximum torque and tensile and tear strength. Dynamic mechanical analysis showed that the interaction between GO and NR-g-VTES was better than that of the GO-reinforced NR.

One-step Solvothermal Synthesis of rGO/TiO2 Nanocomposite for Efficient Solar Photocatalytic Degradation of Methylene Blue Dye

Background: The discharge of effluents from the textile and dyeing industries has been a worldwide concern. Although reduced graphene oxide/titanium dioxide (rGO/TiO2) nanocomposite is a potential candidate for wastewater treatment, the influence of graphene oxide (GO) content on its physico-chemical characteristics and its subsequent photocatalytic capabilities in degrading the organic contaminants has not been well established. Objective: The primary objective of this study was to assess the use of rGO/TiO2 nanocomposites with various GO contents for the removal of toxic methylene blue (MB) dye from aqueous solution. Method: In the present study, rGO/TiO2 nanocomposites were fabricated using various GO contents through a one-step solvothermal method. The effect of GO content on the nanocomposite formation was investigated by using field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. The resulting nanocomposites were evaluated against MB degradation under artificial solar light illumination. Results: Based on the photocatalytic results, the highest removal percentage of MB was achieved by 0.15rGO/TiO2, which was about 1.7 times higher than that of 0.01rGO/TiO2. Conclusion: The enhanced removal efficiency of MB by the nanocomposite with the highest GO content (0.15 g) was attributed to the increased active adsorption sites, which greatly promoted the π- π interaction between the aromatic rings of MB dye and the graphitic skeleton of rGO, as well as the electrostatic interaction between the cationic center of MB molecules and the residual oxygen functionalities of rGO.

Effect of percentage of graphene oxide on phase transition of water induced shape memory behavior of PVA-go-PEG hydrogel

Since supramechanical hydrogel was reported, hydrogel has been becoming a popular material to construct specialty features or functions. In this paper, a functional hydrogel made of poly (vinyl alcohol)/graphene-oxide/polyethylene-glycol (PVA-go-PEG) was investigated for the percentage effect of graphene-oxide (GO) on the phase transition of water induced shape memory ability. Experimentally, the hydrogel showed high shape fixed ability at below −5 °C and high shape recovered ratio at above 5 °C for GO content of 0.6%, 0.9% and 1.2%. The temperature range from −5 to 5 °C gives rise to a fixation and recovery dynamics of hydrogel for each GO content, thus the state of aqueous molecules inside hydrogel dominates the dynamic behavior. Characterizations from XRD, FTIR and NMR indicated that the crystalline phase in polymers and the generated hydrogen bonds between GO nanoparticles and macromolecules play key role of netpoints for maintaining hydrogel shape intact. DSC and XRD measured spectra revealed that the phase transition of aqueous molecules in the hydrogel act as switch in the shape memory program. A model for such shape memory mechanism was proposed to explain the effect of GO content on the phase transition of water induced shape memory behavior for the prepared hydrogel. This study inspires to explore high strength and adaptability of hydrogels in application areas of temperature conversion conditions.

Chitosan/graphene oxide mixed matrix membrane with enhanced water permeability for high-salinity water desalination by pervaporation

Pervaporation is a promising technology for water desalination. In this work, graphene oxide (GO) was incorporated into chitosan (CS) to fabricate mixed matrix membranes (MMMs) to explore the enhancement of water permeability for high-salinity water desalination and to understand the transport mechanism in the MMMs. The effect of GO content on the morphology, wettability and desalination performance of the membranes as well as the thermodynamic and kinetic behavior of water and salt permeation in the membranes were investigated. The MMMs have rougher and more hydrophilic surface, dense structure and improved mechanical stability owing to the good chemical compatibility of GO with CS matrix. The apparent activation energy results indicate the advantage of the MMMs in desalinating high-salinity water. The enhanced permeate flux of 30.0 kg/m2·h was obtained in desalinating 5 wt% aqueous NaCl solution at 81 °C with 1 wt% GO content and 99.99% of salt rejection was achieved. The solubility and diffusivity of H2O and NaCl in the MMMs demonstrate a trade-off effect on the water permeability and water/salt selectivity with increasing of GO content. The NaCl diffusion coefficient in the membranes was lower than that of H2O by two orders of magnitude, contributing to the high selectivity of the membrane.

Mechanically viscoelastic nanoreinforced hybrid hydrogels composed of polyacrylamide, sodium carboxymethylcellulose, graphene oxide, and cellulose nanocrystals

Polyacrylamide-sodium carboxymethylcellulose (PMC) hybrid hydrogels reinforced with graphene oxide (GO) and/or cellulose nanocrystals (CNCs) were prepared via in situ free-radical polymerization. In this work, GO nanosheets were freshly synthesized by modified Hummer’s method alongwith the aqueous suspension of CNCs by acid-hydrolysis. In addition, the effect of GO content (1.5 wt%) and CNCs (from 2.5 wt% to 10.0 wt%) was investigated in these quaternary hydrogels. The results showed good pseudo-plastic behavior, self-healing ability, mechanical performance, and shape-recovery behavior of the hybrid hydrogels reinforced with GO and CNCs content. PMC-GO1.5/CNCs10.0 hybrid hydrogel showed 110.5 kPa as compressive strength and stiffness value of 887.7 N/m (at 30% strain). Moreover, the synergistic effect of both GO and CNCs as nanoreinforcements in hydrogels provides a new point of view for the preparation of hybrid hydrogels having exceptional structural and mechanical properties. As-obtained hybrid hydrogels may have potential application in tissue engineering for tunable mechanical properties.

In-situ synthesis of visible-light responsive Ag2O/graphene oxide nanocomposites and effect of graphene oxide content on its photocatalytic activity

Ag2O/graphene oxide nanocomposites, as efficient photocatalysts, were prepared by an in situ method using AgNO3 and graphene oxide as reactants under controlled atmosphere. Graphene oxide is synthesised via an eco-friendly method, and the Ag2O nanoparticles displaying elongated spherical morphology are randomly distributed on the surface of GO. The as-synthesised nanocomposites were characterised by different characterisation techniques. The results proved that the concentration of graphene oxide in starting solution displayed an important role in photocatalytic performance of Ag2O/graphene oxide nanocomposites. The nanocomposite materials were found to exhibit very improved photocatalytic activity for degrading methylene blue (MB) and Rhodamine B (Rh-B) under visible light irradiation. The photocatalytic activities of the composite were higher than that of P25 (a commercial TiO2 as a benchmark photocatalyst). The significantly improved photocatalytic activity of the nanocomposites could be attributed to the high charge separation and suppressed recombination of photogenerated electron-hole pairs due to GO. The effects of reaction parameters such as pH and the effect of different scavengers on the photocatalytic activity of the composite were studied.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/Graphene Oxide Nanocomposite Films: Thermomechanical Properties, Oxygen Transmission Rates, and Hydrolytic Degradation

In this study, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)/graphene oxide (GO) nanocomposite films containing various content of GO were prepared using solution casting method. The effect of GO content on Young`s modulus and dispersion of GO in PHBV matrix was investigated. Also, the thermomechanical properties, oxygen transmission rates and hydrolytic degradation of PHBV/GO nanocomposite films were studied. The addition of GO into PHBV improves the Young`s modulus and decreases thermal expansion coefficient. The improvement can be mainly attributed to good dispersion of GO and interfacial interactions between PHBV and GO. Furthermore, PHBV/GO nanocomposite films show good oxygen barrier properties. PHBV/GO nanocomposites show lower hydrolytic degradation rates with increasing content of GO.

PH-controlled drug release of radiation synthesized graphene oxide/(acrylic acid-co-sodium alginate) interpenetrating network

Hydrogel biocomposites containing a combination of graphene oxide (GO) and natural polymer-based copolymer of sodium alginate (Alg) and acrylic acid (AAc) were prepared by radiation-induced copolymerization and crosslinking. FTIR, XRD, and AFM analyses revealed the successful preparation of single-layered graphene oxide sheets. FTIR and TGA data confirmed the incorporation of GO within the (AAc-co-Alg) copolymer hydrogel. The effect of GO content, as interpenetrating network, on the swelling behavior of (AAc-co-Alg) copolymer hydrogel was investigated. The results of the pH-dependent swelling showed the presence of GO within the prepared hydrogel improve the ability of the GO/(AAc-co-Alg) nanocomposite hydrogel to bypass the acidity of the simulated stomach medium (pH 1) without significant swelling and regulate it for longer period in simulated intestine medium (pH 7). Moreover, the swelling kinetics showed that all the samples under investigation possess Fickian at pH 1 and non-Fickian at pH 7. The evaluation of the prepared GO/(AAc-co-Alg) nanocomposite hydrogel as drug carrier was carried out in either simulated stomach and intestine media using cefadroxil as a model drug. The drug release profile came in a good agreement with swelling results which recommend the GO/(AAc-co-Alg) nanocomposite hydrogel as potential targeted drug delivery system.

Novel carboxymethyl chitosan-graphene oxide hybrid particles for drug delivery.

We describe an electrostatic droplet generation method to prepare a novel carboxymethyl chitosan-graphene oxide hybrid particles for delivery purpose. Under an adjustable electrostatic field, graphene oxide and carboxymethyl chitosan mixed solution was sprayed as uniform micro-droplets, which were solidified as particles in CaCl2 solution. Such hybrid particles are wished to have excellent stability in saline solution, and better delivery properties than pristine carboxymethyl chitosan particles. The effects of micro-droplets generation conditions on particles formation were systematically investigated. At conditions of 40 mg/ml of carboxymethyl chitosan, 2 mg/ml of graphene oxide, 3 ml/h of feed speed, electrostatic field parameters was 9 kV and 20 cm, uniformly sized carboxymethyl chitosan-graphene oxide particles in the diameter range of 250-300 μm was successfully prepared. In NaCl saline, these particles could maintain stable for at least a week, while pristine carboxymethyl chitosan particles quickly collapsed within an hour. The results of loading experiments showed that carboxymethyl chitosan-graphene oxide particles could effectively adsorb gatifloxacin, ofloxacin, bovine serum albumin, lysozyme, doxorubicin hydrochloride. And gatifloxacin was chosen as a model drug to study the exact effect of graphene oxide content on the loading and release properties. In 40:2 group, the highest loading capacity of 0.45 ± 0.19 mg/mg was achieved, and also a good sustained release was available. Above all, we believed that carboxymethyl chitosan-graphene oxide particles as a versatile carrier, has great potential in Medicine and Pharmacy.

Physico-mechanical properties of a microwave-irradiated kenaf carbamate/graphene oxide membrane

Cellulose carbamate (CC) prepared using microwave irradiation was reinforced with graphene oxide (GO) to fabricate homogeneous and highly ordered CC–GO membranes using a simple solution-mixing method. The effect of GO content on the properties of the membranes was investigated. Atomic force microscope and transmission electron microscope images indicated that the self-synthesized GO nanosheets exhibited exfoliated layers within the CC. X-ray diffraction results confirmed the crystalline structure of cellulose I and cellulose II in the CC pulp and CC–GO membranes, respectively. Increasing the GO content from 0 to 4 wt% resulted in a slight decrement in the crystallinity index. The membrane containing 4 wt% GO possessed a tensile modulus and strength higher by approximately 525 and 93 %, respectively, compared to the neat CC. Thermogravimetric analysis proved that the GO promoted higher thermal stability and carbon yields. The 3D homogeneous porous structures of the CC–GO membranes were viewed under a field emission scanning electron microscope. These improvements in the membrane properties were confirmed by Fourier transform infrared spectroscopy and are attributed to the strong and effective interactions between CC and GO.
