A Competitive Study Using Electrospinning and Phase Inversion to Prepare Polymeric Membranes for Oil Removal.

Polyacrylonitrile (PAN) is a popular polymer that can be made into membranes using various techniques, such as electrospinning and phase inversion. Electrospinning is a novel technique that produces nonwoven nanofiber-based membranes with highly tunable properties. In this research, electrospun PAN nanofiber membranes with various concentrations (10, 12, and 14% PAN/dimethylformamide (DMF)) were prepared and compared to PAN cast membranes prepared by the phase inversion technique. All of the prepared membranes were tested for oil removal in a cross-flow filtration system. A comparison between these membranes' surface morphology, topography, wettability, and porosity was presented and analyzed. The results showed that increasing the concentration of the PAN precursor solution increases surface roughness, hydrophilicity, and porosity and, consequently, enhances the membrane performance. However, the PAN cast membranes showed a lower water flux when the precursor solution concentration increased. In general, the electrospun PAN membranes performed better in terms of water flux and oil rejection than the cast PAN membranes. The electrospun 14% PAN/DMF membrane gave a water flux of 250 LMH and a rejection of 97% compared to the cast 14% PAN/DMF membrane, which showed a water flux of 117 LMH and 94% oil rejection. This is mainly because the nanofibrous membrane showed higher porosity, higher hydrophilicity, and higher surface roughness compared to the cast PAN membranes at the same polymer concentration. The porosity of the electrospun PAN membrane was 96%, while it was 58% for the cast 14% PAN/DMF membrane.

Lignin particles as green pore-forming agents for the fabrication of microporous polysulfone membranes

Templating polymeric membranes with micro-nano-scaled solid materials is an effective method to simultaneously improve the water flux and retention ratio. However, the fabrication of a green, recyclable, and size-controlled template material remains a challenge. Here, a new green pore-forming agent, lignin particles (LP), was developed to prepare porous polysulfone (PSF) membranes via the phase inversion technique. A series of LP have uniform sizes from ~200 nm to ~1800 nm. The performances of the templated PSF membranes cast at different sizes and contents of LP were examined for their surface and crosssection morphologies. The LP-templated PSF membranes displayed a remarkable enhancement in flux, porosity, and moisture content. Particularly, the PSF membranes cast with LP from ~200 to 1800 nm broke the traditional trade-off to a certain degree, which possessed stable retentions of bovine serum albumin (> 85 %) and significantly improved water flux (174.275 to 254.775 L m−2 h−1). In addition, the LP pore-forming agent is low-cost and environmentally friendly as it was prepared from industrial by-products and can be easily recycled. Overall, this study shows that lignin particles are green pore-forming agents that can be used for the fabrication of porous polymeric membranes with improved performance for water treatment.

Non-Equilibrium Block Copolymer Self-Assembly Based Porous Membrane Formation Processes Employing Multicomponent Systems.

Porous polymer-derived membranes are useful for applications ranging from filtration and separation technologies to energy storage and conversion. Combining block copolymer (BCP) self-assembly with the industrially scalable, non-equilibrium phase inversion technique (SNIPS) yields membranes comprising periodically ordered top surface structures supported by asymmetric, hierarchical substructures that together overcome performance tradeoffs typically faced by materials derived from equilibrium approaches. This review first reports on recent advances in understanding the top surface structural evolution of a model SNIPS-derived system during standard membrane formation. Subsequently, the application of SNIPS to multicomponent systems is described, enabling pore size modulation, chemical modification, and transformation to non-polymeric materials classes without compromising the structural features that define SNIPS membranes. Perspectives on future directions of both single-component and multicomponent membrane materials are provided. This points to a rich and fertile ground for the study of fundamental as well as applied problems using non-equilibrium-derived asymmetric porous materials with tunable chemistry, composition, and structure.

Enhanced adsorptive removal of As(V) ions in aqueous solution using polyethersulfone ultrafiltration mixed matrix membranes impregnated with 3‐aminopropyltriethoxysilane modified magnetite Fe3O4 nanoparticles

AbstractThis study involves the fabrication of mixed matrix membranes (MMMs) for ultrafiltration, which contained 3‐aminopropyltriethoxysilane modified magnetite iron oxide nanoparticles (A‐Fe3O4 NPs), through a modified phase inversion technique. The physiochemical properties and surface morphologies of both the as‐synthesized A‐Fe3O4 NPs and fabricated MMMs were examined using advanced characterization techniques. The quasi‐spherical A‐Fe3O4 NPs had an average particle size of 12 nm and a Brunauer–Emmett–Teller surface area of 131.38 m2/g. Analysis by Fourier transform infrared and Raman spectroscopy confirmed the presence of NH2 and OH functional groups grafted onto the Fe3O4 NPs. The incorporation of higher loadings of A‐Fe3O4 NPs in the membrane matrix significantly improved the adsorptive ability and hydrophilicity of the adsorbent, leading to improved membrane water permeance, adsorption rate, and adsorption‐filtration properties. The water contact angle decreased from 70.7° to 63.2°, and the flux increased from 239.9 to 443.8 L/m2.h, while overall membrane porosity increased from 43.4% to 51.9%.

Evaluation of Crosslinking Degree on the Integral Membrane by using Rice Husk Ash (RHA)

Rice husk ash (RHA) is a waste product from the harvesting and processing of rice that contains a high quantity of silica, approximately 95% after combustion. Membrane technology is being developed to remove impurities like heavy metals and dyes as the natural environment deteriorates and water supplies become scarce. Many researchers and developers are now adopting this type of technology. However, it has various drawbacks such as being costly and easily being fouled during the separation process. Therefor e, matrix modification of the membrane should be carried out to mitigate these problems. The incorporation of fillers from biomass materials is one of the ways. This research aims to demonstrate the significant effect of incorporating the extracted silica from rice husk ash (RHA) in a polymer-based membrane from a blend of Polyvinyl alcohol/chitosan/polysulfone on the membrane characteristics and antifouling properties. The membranes were prepared by using a phase inversion technique by the incorporation of silica from rice husk ash (RHA) at various concentrations such as 5 wt.%, 7.5 wt.%, and 10 wt.% with a fixed amount of the polymer blends. The results showed that the integral membrane M4 with 10wt.% silica has the best hydrophilicity properties and possesses excellent antifouling properties, which were portrayed through the greater value of pure water flux (PWF) of 20.38 L/m2.h and the highest flux recovery ratio of 76.32%. This study has proven the potential utilization of ricehusk ash to enhance the membrane properties for industrial wastewater treatment.

Preparation and Characterization of Novel Membrane from Waste Polyethylene terephthalate and Bio-based Polymer

A large amount of post-consumer Polyethylene terephthalate (PET) bottle waste could be recycled for downstream products. In this work, used PET bottles were utilized as a raw material to develop environmentally-friendly ultrafiltration membranes by phase inversion technique. Poly(ethylene-2,5-furandicarboxylate) (PEF), prepared from a sustainable bio-based monomer, 2,5-furandicarboxylic acid (FDCA), was blended into rPET matrix to improve the mechanical properties of the membrane. Ethanol was also used as a non-solvent in a coagulation bath and polyethylene glycol (PEG) with a molecular weight of 400 Da was added as a hydrophilic additive. The effects of PEF and PEG incorporation to waste PET-based membranes have been thoroughly studied. The morphology of obtained membrane was investigated using Scanning Electron Microscopy (SEM). The membrane’s permeation and resistance were tested using a pressure-driven dead-end membrane module. The result revealed that adding PEF increased the roughness of the membrane surface, which lowered the flux recovery ratio and rejection performance. However, the filtration performance and the membrane resistance could be improved by adjusting the content of the PEG additive.

Separation of oil-water emulsion by cellulose acetate ultrafiltration membranes

ABSTRACT This study reports the separation of oil from water using cellulose acetate (CA) ultrafiltration (UF) membranes. The CA membranes were fabricated by varying bath temperatures such as 5 ± 2°C, 25 ± 2°C and 45 ± 2°C using the phase inversion technique and assess their performance based on the oil removal efficiency. Changing the coagulation bath temperature (CBT) at that stage of membrane formations affects the porosity, pore size, hydraulic resistance, morphological structure and performance of membranes. The obtained results revealed increased porosity and pore size and also decreased hydraulic resistance of the membranes as the CBT increases. Field Emission Scanning Electron Microscopy (FESEM) images indicate that a large number of surface pores are visibly found at the higher bath temperature. Atomic force Microscopy (AFM) images show increased average roughness (R a) of the membrane as the CBT of the membrane increases. The water flux and permeate flux of all the membranes tend to increase with an increase in CBT. From Chemical Oxygen Demand (COD) studies, the oil removal efficiency was maximum for the lower bath temperature membrane. The results indicate that conditions of the coagulation bath significantly affect the porous structure, morphology and performance of the membrane.

A TiO2 modified whisker mullite hollow fiber ceramic membrane for high-efficiency oil/water emulsions separation

Design and preparation of membranes with ultrahigh separation performance and antifouling property for oil-in-water (O/W) emulsions remains challenging. In this study, a high flux mullite/TiO2 ceramic composite membrane was prepared via multi-precipitation of TiO2 on a whisker mullite hollow fiber support synthesized by combining phase inversion and high-temperature sintering techniques. The results showed that the generated whisker mullite structure improved the permeation flux, and the micro-nano structured TiO2 functional layer endowed the membrane surface with superhydrophility and stability. The retention of the optimal composite membrane (M20T13) that was soaked in the titanium solution 20 times for 13 min each time for the O/W emulsions like n-hexane, toluene and engine oil maintained over 98 %, and the flux after 6 h filtration was 668.34 L·m−2·h−1, 487.25 L·m−2·h−1 and 258.66 L·m−2·h−1, respectively, much higher than that of the optimal substrate (F3A1, mass ratio of fly ash: Al2O3 = 3:1). Moreover, the flux recovery rate of M20T13 was much higher than that of F3A1 after chemical backwashing. This work manifests great potential in O/W treatment fields.

Electrical impedance spectroscopy for non-destructive detection of wetting, fouling and scaling in membrane distillation

Wetting, fouling, and scaling of hydrophobic membranes are significant constraints in membrane distillation (MD) technology. In recent research trends, novel membrane fabrication has been given utmost priority to address these constraints, majorly induced by the low surface tension chemicals like surfactants and dissolved organic matters present in the feed water. In this research, we fabricated a hydrophobic membrane using phase inversion technique with polyvinylidene fluoride (PVDF) polymer under an alcohol coagulation bath (ethanol). The wetting, fouling, and scaling of the membrane were monitored using electrochemical impedance spectroscopy (EIS) incorporated with direct contact membrane distillation (DCMD). The surface tension (52.14–27.5 mN m−1) of the synthetic brine water was reduced by adding surfactant, whereas model algal organic matters were dissolved to study the organic fouling. In the fabricated PVDF membrane, an asymmetric interconnected pore structure was obtained with a high hydrophobicity (water contact angle 146°). A narrow pore size distribution (∼0.43 μm), raised liquid entry pressure (∼1.3 bar), porosity (∼75 %), high surface roughness (1.06 μm), and low surface energy (∼28 mN m−1) were noticed with the same membrane. Hence, it qualified for DCMD application under different feed compositions. Different stages of pore wetting and their progress were assessed instantaneously by adopting EIS approach. Further, the permeate side conductivity was correlated with impedance measured during EIS. Advanced proficiency in distinguishing intrusion and different stages of wetting was illustrated.

Impact of Nanoclays on Polyvinylidene Fluoride Mixed Matrix Membranes for the Efficient Treatment of Oily Wastewater

Background: Membrane technology demonstrated a sustainable methodology for water reclamation from oily-wastewater, but it is prone to fouling during longer filtration runs. In this study, fouling resistant polyvinylidene fluoride (PVDF) mixed matrix membranes (MMMs) containing nanoclays such as halloysite (HT) and montmorillonite (MMT) were fabricated for the effective treatment of oily wastewater. Methods: Phase inversion technique was followed for the fabrication of HT-PVDF and MMT-PVDF MMMs. Physiochemical characterization and filtration experiments were studied to evaluate the influence of nanoclays on PVDF membrane performance. Results: Fourier transform infrared spectroscopy (FTIR) and morphology analyses indicated that both nanoclays are layered structured with abundant hydrophilic functional groups. The dispersions of HT and MMT were confirmed by surface morphology and topography analysis of PVDF MMMs. The hydrophilicity property was improved in HT-PVDF and MMT-PVDF MMMs, which was evident in the contact angle analysis. Among the membranes, MMT-PVDF MMMs held the higher water permeability of 2.59 x10-8 m/s.kPa. For oil-water filtration, HT-PVDF and MMT-PVDF MMMs displayed higher normalized flux with maximum rejection of more than 95%. Conclusion: Overall, MMT would be cost-effective nanofiller for the development of antifouling PVDF MMMs against oil-water filtration.

A Novel Strategy for Enhanced Sequestration of Protein-Bound Uremic Toxins Using Smart Hybrid Membranes.

Currently available hemodialysis (HD) membranes are unable to safely remove protein-bound uremic toxins (PBUTs), especially those bonded to human serum albumin (HSA). To overcome this issue, the prior administration of high doses of HSA competitive binders, such as ibuprofen (IBF), has been proposed as a complementary clinical protocol to increase HD efficiency. In this work, we designed and prepared novel hybrid membranes conjugated with IBF, thus avoiding its administration to end-stage renal disease (ESRD) patients. Two novel silicon precursors containing IBF were synthesized and, by the combination of a sol-gel reaction and the phase inversion technique, four monophasic hybrid integral asymmetric cellulose acetate/silica/IBF membranes in which silicon precursors are covalently bonded to the cellulose acetate polymer were produced. To prove IBF incorporation, methyl red dye was used as a model, thus allowing simple visual color control of the membrane fabrication and stability. These smart membranes may display a competitive behavior towards HSA, allowing the local displacement of PBUTs in future hemodialyzers.

Preparation of novel Polyvinylidene fluoride/boehmite composite membrane made using nonsolvent induced phase separation method for arsenate ion removal from water

AbstractPolyvinylidene fluoride/boehmite composite membranes with hydrophilic surfaces were prepared using the nonsolvent induced phase inversion technique (NIPS) method to remove arsenate ions from water. The nanoparticles were added with different boehmite filler content. The contact angle of the bare membrane is 850, and it is reduced to 530, imparting hydrophilicity due to the presence of boehmite nanoparticles. The mechanical characteristics of the membranes have significantly improved. The BET and SEM results have shown that the average pore diameter gets reduced with boehmite addition, and surface area increases. Additionally, the use of nanoparticles enhanced the membranes' thermal stability. The nanofiltration unit is used to filter the arsenic‐contaminated water. The transmembrane pressure of ~4 bar is applied to all the membranes, and arsenic rejection; the flux of the membranes was calculated. The membrane has shown the highest rejection of 55% with a flux of 3.5659 L/m2.h.

Development of Novel Fouling-Resistant Hollow Fibre Nanocomposite Membrane Augmented with Iron Oxide Nanoparticles for Efficient Rejection of Bisphenol A from Water: Fouling, Permeability, and Mechanism Studies

Recently, frequent discharge of water-ladened emerging organic pollutants such as Bisphenol A has elicited serious concern due to its pernicious effects on public health and the ecological environment. In this study, hematite nanoparticles (Fe2O3) were synthesized via the sol–gel auto-combustion technique and incorporated as a nanofiller to fabricate a PVDF-PEG nanocomposite hollow fibre membrane with enhanced antifouling properties. A series of membranes comprising various loadings (1.0–2.0 wt%) of Fe2O3 NPs were fabricated through the phase inversion technique and thoroughly analyzed. The developed Fe2O3-membrane fibres were thoroughly characterized. The performance of the membrane fibres was investigated through permeation flux, BPA rejection, as well as antifouling characteristics. Based on the results obtained, the resultant nanocomposite membrane fibres exhibited superior performance in comparison with the pristine fibre. Also, the nanocomposite membrane with 1.5 wt%-Fe2O3 NPs exhibited remarkable performance with − 43.7 mV, 56.3º, 191.85 L/m2 h, 86.7%, and 12% of negatively charged zeta potential, least contact angle, water permeation flux, BPA rejection, and minimum weight loss, respectively. Besides, the 1.5 wt-Fe2O3 NPs nanocomposite membrane demonstrated superior antifouling performance after the third filtration, accomplishing a higher percent of FRR (77.35%) along with RFR of 21.29%, respectively. Hence, based on the performance of the fabricated hollow-fibre membranes loaded with Fe2O3 NPs, efficient antifouling membranes was achieved which can be suitably applied in the purification of industrial wastewater.

Synergistic effects on BiFeO3 based cellulose acetate composite and efficient photocatalytic activities for wastewater treatment application

A photocatalyst composite film comprising cellulose acetate (CA)-supported bismuth ferrite (CA-BFO) was successfully fabricated using a phase-inversion technique. The composite was used to assess the removal efficiency for a mixture of crystal violet (CV) and indigo carmine (IC) dyes under direct sunlight. The effects of pH, amount of adsorbent, initial dye concentration, and contact time were investigated. The results indicated that the optimum pH for the removal of both cationic and anionic dyes was 6.0. The best catalyst loading of 0.04 g/L of BiFeO3 distributed in the cellulose acetate membrane could degrade up to 100 ppm of mixed dyes and remain efficient over a wide pH range. The results were consistent with those of single dye removal, with the composite exhibiting preferential adsorption to anionic dyes, IC and having a higher photocatalytic affinity for cationic dyes, CV. Thus, a synergistic mode of CV and IC dye removal by adsorption and photodegradation was proposed. Moreover, the composite approach is a promising alternative for the co-existence of cationic and anionic dye removal from wastewater because of its high efficiency and separation convenience.

Cellulose Acetate Membranes: Fouling Types and Antifouling Strategies—A Brief Review

Cellulose acetate (CA) is a semisynthetic, biodegradable polymer. Due to its characteristics, CA has several applications, including water membranes, filament-forming matrices, biomedical nanocomposites, household tools, and photographic films. This review deals with topics related to the CA membranes, which are prepared using different techniques, such as the phase inversion technique. CA membranes are considered very important since they can be used as microfiltration membranes (MF), ultrafiltration membranes (UF), nanofiltration membranes (NF), reverse osmosis (RO) membranes, and forward osmosis (FO) membranes. Membrane fouling results from the accumulation of materials that the membrane rejects on the surface or in the membrane’s pores, lowering the membrane’s flux and rejection rates. There are various forms of CA membrane fouling, for instance, organic, inorganic, particulate fouling, and biofouling. In this review, strategies used for CA membrane antifouling are discussed and summarized into four main techniques: feed solution pretreatment, cleaning of the membrane surface, membrane surface modification, which can be applied using either nanoparticles, polymer reactions, surface grafting, or surface topography, and surface coating.

Hybrid Inorganic Organic PSF/Hap Dual-Layer Hollow Fibre Membrane for the Treatment of Lead Contaminated Water

Lead (Pb) exposure can be harmful to public health, especially through drinking water. One of the promising treatment methods for lead contaminated water is the adsorption-filtration method. To ensure the cost-effectiveness of the process, naturally derived adsorbent shall be utilised. In this study, hydroxyapatite particles, Ca10(PO4)6(OH)2 (HAP) derived from waste cockle shell, were incorporated into the outer layer of polysulfone/HAP (PSf/HAP) dual-layer hollow fibre (DLHF) membrane to enhance the removal of lead from the water source due to its hydrophilic nature and excellent adsorption capacity. The PSf/HAP DLHF membranes at different HAP loadings in the outer layer (0, 10, 20, 30 and 40 wt%) were fabricated via the co-extrusion phase inversion technique. The performance of the DLHF membranes was evaluated in terms of pure water flux, permeability and adsorption capacity towards lead. The results indicated that the HAP was successfully incorporated into the outer layer of the membrane, as visibly confirmed by microscopic analysis. The trend was towards an increase in pure water flux, permeability and lead adsorption capacity as the HAP loading increased to the optimum loading of 30 wt%. The optimized DLHF membrane displayed a reduced water contact angle by 95%, indicating its improved surface hydrophilicity, which positively affects the pure water flux and permeability of the membrane. Furthermore, the DLHF membrane possessed the highest lead adsorption capacity, 141.2 mg/g. The development of a hybrid inorganic-organic DLHF membrane via the incorporation of the naturally derived HAP in the outer layer is a cost-effective approach to treat lead contaminated water.

Verification of Estimated Output Signal-to-Noise Ratios From a Phase Inversion Technique Using a Simulated Hearing Aid.

The signal-to-noise ratio (SNR) for speech presented in background noise may vary after being processed by digital hearing aids with nonlinear signal processing algorithms, such as wide dynamic range compression (WDRC). A phase inversion technique has been previously developed to assess the output SNR of hearing aids. However, systematic validations of this technique have not been conducted. This study aims to validate the phase inversion technique. A simulated hearing aid with multichannel WDRC was implemented, from which the output SNRs, computed via shadow filtering, for connected speech in background noise were directly computed. The agreement between the shadow filter output SNRs and those estimated using the phase inversion technique for the same stimuli was utilized to validate the phase inversion technique. The background noise was 2- or 20-talker babble noise, and the speech stimuli were presented at SNRs of -10 to +10 dB at the input of the simulated hearing aid. The simulated hearing aid was configured to provide amplification for four representative audiograms, and the WDRC was set to be fast or slow acting. To investigate the effects of additive noise, independent of the presented noise stimulus, on the phase inversion estimated output SNR, the same simulated hearing aid was implemented with an additive Gaussian noise at its input (45 and 60 dB SPL). Results showed that the phase inversion technique could either overestimate or underestimate output SNR, depending on the test condition; the estimation errors tended to coincide with temporal landmarks, such as natural pauses between consecutive sentences or fricatives; and increasing the simulated noise led to poorer estimates of output SNR. Results imply that the accuracy of the phase inversion technique is dependent on the test conditions. Thus, the phase inversion technique should be used with caution, and its validity should be evaluated further.

Evaluation of physical stability of whey protein-stabilized red palm oil emulsion by monitoring the changes of droplets characteristics

The physical stability of a whey protein (WP)-stabilized red palm oil (RPO) emulsion as affected by the type and concentration of WP used was evaluated by monitoring the changes in its droplet characteristics after storage and accelerated testing. Emulsions containing 30% (v/v) RPO were stabilized by WP isolate 90 (WPI), WP concentrate 80 (WPC80), or WP concentrate 76 (WPC76) at various concentrations (2.5–15% (w/v)) via emulsification employing a two-step rotor-stator homogenization combined with a phase inversion technique. Based on the results, changes in droplet characteristics did not always represent the visually observed stability of the emulsions. In this study, WPCs performed better than WPI in forming a stable RPO emulsion. Higher WP concentrations produced smaller emulsion droplet sizes with better emulsion stability when stored at varied temperatures (i.e., 30 °C, 45 °C, and 60 °C). However, when stored at 60 °C, all the emulsions produced were least stable. Based on the results, the 15% WPC76-stabilized emulsion showed the best stability. This study found that the droplet size characterization could not fully explain the stability of the emulsion, and the emulsion investigated destabilized through different dominant mechanisms when it was stored compared to when it was centrifuged. This study provides information needed for developing a stable WP-stabilized emulsion to be the RPO carrier system.

Cobalt-free SrFe1−xMoxO3-δ perovskite hollow fiber membranes for oxygen separation

SrFe0.95Mo0.05O3-δ (SFM5) perovskite hollow fiber (HF) membranes with a finger-like structure were fabricated by a phase inversion technique. The oxygen flux through SFM5 hollow fiber membrane was evaluated and reached 0.64 μmol/cm2 *s at T = 880 °C, which is 5 times higher than that of a disk SFM5 membrane (0.12 μmol/cm2 *s). A further increase in oxygen fluxes was attained by Ag deposition on the inner surface of SFM5 hollow fiber membrane. The oxygen flux of SFM5 HF membranes is governed by surface-exchange reactions on the permeate side. The equilibrium "3 − δ − lg pO2 − T" diagrams showed that doping of SF by molybdenum leads to a broadening of the cubic perovskite phase stability region.

Carboxylated Graphene Oxide (c-GO) Embedded ThermoPlastic Polyurethane (TPU) Mixed Matrix Membrane with Improved Physicochemical Characteristics.

Water is an important component of our life. However, the unavailability of fresh water and its contamination are emerging problems. The textile industries are the major suppliers of contamination of water, producing high concentrations of heavy metals and hazardous dyes posing serious health hazards. Several technologies for water purification are available in the market. Among them, the membrane technology is a highly advantageous and facile strategy to remediate wastewater. Herein, the distinguished combination of pore-forming agents, solvent, and nanoparticles has been used to achieve improved functioning of the polymeric composite membranes. To do so, graphene oxide (GO) was fabricated via Hummer's technique and GO functionalization using chloroacetic acid (c-GO) was performed. Thermoplastic polyurathane (TPU) membranes having different concentrations c-GO were made using the phase inversion technique. Scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FT-IR), and X-ray diffraction (XRD) was used to examine surface morphology, chemical functionalities on membranes surfaces, and crystallinity of membranes, respectively. The temperature-dependent behavior of c-GO composite membranes has been analyzed using DSC technique. The water contact angle measurements were performed for the estimation of hydrophilicity of the c-GO based TPU membrane. The improved water permeability of the composite membrane was observed with increasing the c-GO concentration in polymeric membranes. c-GO was observed as a potential candidate that enhanced membrane physicochemical properties. The proposed membranes can behave as efficient candidates in multiple domains of environmental remediation. Furthermore, the improved dye rejection characteristics of proposed composite membranes suggest that the membranes can be best suited for wastewater treatment as well.
