Novel polycaprolactone-based biomimetic grafts enriched with graphene oxide and cerium oxide: Exploring improved osteogenic potential

In bone tissue engineering, the development of advanced biomaterials is crucial to address the challenges associated with the treatment and regeneration of bone defects. This study presents a novel polymeric nanocomposite consisting of Polycaprolactone (PCL) integrated with graphene oxide (GO) and cerium oxide (CeO2) nanoparticles, aiming to comprehensively explore its multifaceted potential for bone tissue engineering applications. The physicochemical properties of the composite films were analyzed. Biodegradation studies showed superior degradability to pure PCL due to added hydrophilic features and increased nanofiller-induced surface porosity. The remarkable improvement in mechanical stability is attributed to the uniform dispersion of nanofillers. Assessments of surface wettability, demonstrate a noteworthy shift towards heightened hydrophilicity, rendering a more conducive environment for biomolecules. The hybrid polymer nanocomposite exhibits remarkable hemocompatibility, antibacterial properties, antioxidant activity, and excels in facilitating apatite deposition and promoting osteogenic differentiation. Biomineralization investigations and ARS assay underscore the nanocomposite's exceptional ability to promote apatite deposition, a pivotal mineral in bone formation, owing to the altered surface properties introduced by the nanofillers. The ALP findings imply that the PCL-GO-CeO2 nanocomposite actively supports and accelerates the process of osteogenic differentiation in MSCs, indicating its potential utility in bone tissue engineering. Additionally, cell culture studies conducted on HOS and rBMSC cell lines validate the nanocomposite's excellent cell viability, attachment, and proliferation, affirming its biocompatibility and potential for bone tissue engineering. Collectively, these findings establish PCL-GO-CeO2 nanocomposite as a favourable option for enhancing bone regeneration.

Artificial Intelligence prediction and optimization of the mechanical strength of modified Natural Fibre/MWCNT polymer nanocomposite

Artificial Intelligence (AI), techniques like artificial neural networks (ANN), and machine learning have been used to solve a variety of engineering problems. In this study, Multiwall Carbon Nanotube (MWCNT) and Natural Fibres (NF) from plantain (Musa Paradisiaca) fiber (PF), were utilized to prepare a reinforced hybrid polymer nanocomposite for advanced composite applications. A chemical solution containing potassium permanganate (KMnO4) in acetone (C3H6O) was applied to modify the fibers to alter their surface and improve adhesion and interaction between the PF/polymer matrix. To predict and optimize the tensile strength (TS) of the prepared PF/MWCNT hybrid nanocomposite (PFMNC), the ANN model with hyper-parameter optimization in a single-layer-perceptron architecture of 3-5-1 was used with 5 neurons in the hidden layer, and Box-Behnken Design (BBD) was utilized. Scanning electron microscope (SEM) micrographs demonstrate that KMnO4 modification has impacted the TS of the hybridized nanocomposite. Mechanical Test results show that these variables impacted the TS of the PFMNC as shown by analysis of variance (ANOVA) with R2 = 0.9986. The expected findings were nearly identical to the experimental results. The model predicted an optimal tensile strength of 46.1563 Mpa. To substantiate the reliability of the empirical experimental investigation, TS analysis was performed at predicted optimal settings. TS results showed an average strength of 45.4401 Mpa. About 98.45 % of the projected tensile strength is accounted for by the model. The present study has demonstrated the effectiveness of the ANN-BBD modeling technique in achieving the appropriate mechanical property values quickly, reducing production costs, and preserving resources.

Modification of thermal and electrical characteristics of hybrid polymer nanocomposites through gamma irradiation for advanced applications

In this article, we present a straightforward in-situ approach for producing Ag NPs incorporated in graphene oxide (GO) blended with glutaraldehyde (GA) cross-linked polyvinyl alcohol (PVA) matrix. Samples are γ-irradiated by doses of 2, 5, and 10 kGy and in comparison with the pristine films, the thermal conductivity (‘k’) and effusivity are measured. ‘k’ decreases with irradiation doses up to 5 kGy and further increase in the dosage results increase in ‘k’. We performed FDTD modeling to verify the effect of polarization and periodicity on the absorptivity and emissivity spectra that are correlated to the ‘k’ and effusivity, empirically. Hence, we can confess that the structural properties of the prepared hybrid nanocomposite are manipulated by γ-irradiation. This attests that the PVA/GO-Ag/GA nanocomposite is radiation-sensitive and could be employed for thermal management systems. Moreover, their strong electrical insulation, as the measured dc conductivity of the γ-irradiated samples is found to be in the range of 2.66 × 10−8–4.319 × 10−7 Sm−1, which is below the percolation threshold of 1.0 × 10−6 Sm−1, demonstrates that they are excellent candidates for the use of thermal management materials. The low ‘k’ values allow us to use this promising material as thermal insulating substrates in microsensors and microsystems. They are also great choices for usage as wire and cable insulation in nuclear reactors due to their superior electrical insulation.Graphical

Utilizing multicriteria decision‐making approach for material selection in hybrid polymer nanocomposites for energy‐harvesting applications

AbstractFlexible and cost‐effective poly(vinylidene fluoride) (PVDF)‐based composites having excellent piezo performance are quite interesting for developing actuators, sensors, and nanogenerators. In this work, a hybrid PVDF‐based nanocomposite consisting of a fixed quantity of titanium dioxide (TiO2) and varying quantities of reduced graphene oxide (rGO) for increased mechanical and piezoelectric performance is reported for the first time. Compared to pure PVDF, there is a significant enhancement in mechanical properties for hybrid nanocomposites. The highest piezoelectric voltage as well as current values of 10.2 V and 0.78 μA are recorded for a hybrid nanocomposite containing 1 wt% of rGO for continuous finger‐tapping operation. A multicriteria decision‐making (MCDM)‐based material selection and optimization technique called TODIM is applied, and a sensitivity study is carried out to select the best material for mechanical energy harvesting applications. A hybrid nanocomposite based on PVDF‐TiO2 with 1% rGO loading is the most suitable material according to the TODIM (an acronym in Portuguese for Interactive Multicriteria Decision Making) approach.Highlights PVDF‐TiO2‐rGO nanocomposites are fabricated by solvent casting. TODIM optimization technique is applied for the best material selection among samples. Material ranking consistency shows the reliability of the TODIM method. Conductive rGO increases interfacial polarization, resulting in enhanced ε values. An increment of 88% and 104% in tensile strength and elastic modulus, respectively.

Mechanical characterization of bamboo and glass fiber hybrid composite material

Natural fibers are appealing due to its inexpensive price, small weight, and high specific modulus, renewable nature, as well as biodegradability. Bamboo fibers is one of the most promising natural fibers (along with jute, sisal, bamboo, coir, banana, and others) owing to its low cost, light weight, quick growing cycle, and wide availability. The goal of this paper is to look into fibers orientation reinforced hybrid polymer nano composites that combine BAMBOO/E-GLASS and epoxy polymer in the ratios of E-glass fibre80 percent +bamboo 20 percent, E-glass Fibre70 percent +bamboo 30 percent, and E-glass Fibre60 percent +bamboo 40 percent of volume. The mechanical characteristics will be calculated by performing tests on the specimen's tension, hardness, and flexural qualities in line with ASTM standards. Finally, the values are verified when the testing results have been obtained.

Preparation and characterization of down converting poly (vinyl alcohol)/ PANI@CuS hybrid nanocomposites for optoelectronic application

A new avenue for modifying the physical and chemical characteristics of the semiconducting polymers is opened by the incorporation of conducting polymers coated with inorganic nanoparticles into the semiconducting host polymers. For the manufacture of polyaniline (PANI) composites containing copper sulfide (PANI@CuS) and subsequent introduction to polyvinyl alcohol (PVA), an in-suite polymerization process was used. In the current study, PVA/PANI@CuS hybrid nanocomposites (NCs) were prepared using an environmentally friendly solution casting technique with PANI@CuS concentrations of 0, 1, 2, 3 and 4 ​wt%. To assess their morphological, electrical, optical, and surface characteristics, the prepared polymer hybrid nanocomposites were put through a variety of analytical techniques. The molecular connection between CuS, PANI, and PVA is visible thanks to X-ray diffraction and FT-IR investigations. The refractive index rises from 1.40 to 1.73 while the band gap in the UV–Visible decreases from 6.17 to 3.43, providing information on the optical characteristics. Additionally, photoluminescence spectra exhibit a 150 ​nm Stokes shift towards higher wavelengths, opening up additional opportunities for photovoltaic applications. The electrical characteristics were examined using a scanning electron microscope (SEM), and it was discovered that the conduction mechanism adheres to the Poole-Frenkel effect. The obtained findings demonstrate that the addition of PANI@CuS significantly improves the host polymer matrix's opto-electronic characteristics.

Optimization of mechanical properties of multiscale hybrid polymer nanocomposites: A combination of experimental and machine learning techniques

Machine learning (ML) models provide fast and accurate predictions of material properties at a low computational cost. Herein, the mechanical properties of multiscale poly(3-hydroxybutyrate) (P3HB)-based nanocomposites reinforced with different concentrations of multiwalled carbon nanotubes (MWCNTs), WS2 nanosheets and sepiolite (SEP) nanoclay have been predicted. The nanocomposites were prepared via solution casting. SEM images revealed that the three nanofillers were homogenously and randomly dispersed into the matrix. A synergistic reinforcement effect was attained, resulting in an unprecedented stiffness improvement of 132% upon addition of 1:2:2 wt% SEP:MWCNTs:WS2. Conversely, the increments in strength were only moderates (up to 13.4%). A beneficial effect in the matrix ductility was also found due to the presence of both nanofillers. Four ML approaches, Recurrent Neural Network (RNN), RNN with Levenberg's algorithm (RNN-LV), decision tree (DT) and Random Forest (RF), were applied. The correlation coefficient (R2), mean absolute error (MAE) and mean square error (MSE) were used as statistical indicators to compare their performance. The best-performing model for the Young's modulus was RNN-LV with 3 hidden layers and 50 neurons in each layer, while for the tensile strength was the RF model using a combination of 100 estimators and a maximum depth of 100. An RNN model with 3 hidden layers was the most suitable to predict the elongation at break and impact strength, with 90 and 50 neurons in each layer, respectively. The highest correlation (R2 of 1 and 0.9203 for the training and test set, respectively) and the smallest errors (MSE of 0.13 and MAE of 0.31) were obtained for the prediction of the elongation at break. The developed models represent a powerful tool for the optimization of the mechanical properties in multiscale hybrid polymer nanocomposites, saving time and resources in the experimental characterization process.

Evaluation of Physicochemical Properties of a Hydroxyapatite Polymer Nanocomposite for Use in Fused Filament Fabrication.

Over the last decade, there has been an increasing interest in the use of bioceramics for biomedical purposes. Bioceramics, specifically those made of calcium phosphate, are commonly used in dental and orthopaedic applications. In this context, hydroxyapatite (HA) is considered a viable option for hard tissue engineering applications given its compositional similarity to bioapatite. However, owing to their poor mechanobiology and biodegradability, traditional HA-based composites have limited utilisation possibilities in bone, cartilage and dental applications. Therefore, the efficiency of nano HA (nHA) has been explored to address these limitations. nHA has shown excellent remineralising effects on initial enamel lesions and is widely used as an additive for improving existing dental materials. Furthermore, three-dimensional printing (3DP) or fused deposition modelling that can be used for creating dental and hard tissue scaffolds tailored to each patient's specific anatomy has attracted considerable interest. However, the materials used for producing hard tissue with 3DP are still limited. Therefore, the current study aimed to develop a hybrid polymer nanocomposite composed of nHA, nanoclay (NC) and polylactic acid (PLA) that was suitable for 3DP. The nHA polymer nanocomposites were extruded into filaments and their physiochemical properties were evaluated. The results showed that the addition of nHA and NC to the PLA matrix significantly increased the water absorption and contact angle. In addition, the hardness increased from 1.04 to 1.25 times with the incorporation of nHA. In sum, the nHA-NC-reinforced PLA could be used as 3DP filaments to generate bone and dental scaffolds, and further studies are needed on the biocompatibility of this material.

Mechanical Interlocking Approaches to the Prediction of Mechanical and Tribological Behavior of Natural Fiber-Reinforced Polymer Hybrid Nanocomposites or Automotive Applications

Polymer matrix composites synthesized with biodegradable natural fiber obtain a predominant structure with specific properties at a low-processing cost. The unique characteristics of polymer matrix composites were magnetized in automotive parts like top roof, panel, and seat frame applications. American Society for Testing and Materials (ASTM) G99 analyzed the wear characteristics of synthesized composites through a pin-on-disc wear tester with an EN32 steel disc. The epoxy hybrid composites have been synthesized via a conventional casting process assisted with a mechanical interlock technique to obtain a predominant structure with specific properties at a low-processing cost. The advanced composite contained different jute weights (50, 25, 50, and 75 g) and coconut coir (50, 70, 45, and 20 g) hybridized with graphite particles. ASTM D2240, D638, and D790 standards evaluated the fabricated composite hardness, tensile, and flexural strength. The Sample 4 hybrid composite found maximum hardness, tensile, and flexural strength of 27.41 ± 0.99 Hv, 51.69 ± 1.01MPa, and 55.94 ± 0.78 MPa, respectively. Sample 4 offered good wear resistance of their volumetric wear rate of 0.043 cm3 on 40 N average load at 0.25 m/s sliding speed. It is increased by 12% compared to Sample 1 at 40 N applied load on 2.5 m/s sliding speed.

Composition controllable multifunctionality of PVDF/PMMA/BaTiO3/OMMT based ternary and quaternary hybrid polymer nanocomposites

State-of-the-art engineered multifunctional nanocomposites composed of different polymer matrices and functional nanomaterials are in high industrial demand for advances in all-solid-state flexible device technologies. Within this framework, the host matrices of poly(vinylidene fluoride) (PVDF) and its blend with poly(methyl methacrylate) (PMMA), and the barium titanate (BaTiO3) and organo-modified montmorillonite (OMMT) clay mixed nanomaterial dispersed ternary PVDF/x wt% (BaTiO3+OMMT) and quaternary (PVDF+PMMA)/x wt% (BaTiO3+OMMT) hybrid polymer nanocomposites (HPNCs) are prepared through ultrasonicated homogenized solution casting method. The XRD patterns and FTIR transmittance spectra confirmed the composition dependent crystal phases of the PVDF and the heterogeneous polymer-polymer and polymer-nanomaterial interactions in these HPNC materials. The DSC measurements explained a huge alteration in the PVDF crystallite melting temperatures and also the degree of crystallinity of different HPNC materials. The UV–Vis absorbance of these hybrid materials depends strongly on their composition design and demonstrated dual energy band gaps attributed to host polymer matrices and the nanofillers. The dielectric permittivity dispersion in the broadband frequency range of 20 Hz − 1 GHz explains the contribution of several polarizations and relaxation processes in these complex composites, at 27 °C. Appreciably high dielectric permittivity (4 to 7) in the 20 Hz − 1 MHz range and low permittivity at the ultra high radio frequencies confirmed the promising nanodielectric characteristics of these hybrid materials. The interesting structure-property relationship, tunable energy band gaps, a wide range of composition controllable dielectric permittivity, and frequency dependent electrical conductivity revealed the usefulness of these HPNCs in making flexible-type innovative optoelectronic, capacitive energy storage, and microelectronic devices.

Optical characterization of PVDF/PMMA/OMMT hybrid polymer nanocomposite films for futuristic optoelectronic devices

Hybrid polymer nanocomposite (HPNC) films based on poly(vinylidene fluoride) (PVDF)/poly(methyl methacrylate) (PMMA) blend (80/20 wt/wt%) host matrix and organo-modified montmorillonite (OMMT) nanoclay filler (concentrations 0.0, 2.5, 5.0, and 10 wt%) are prepared by the homogenized solution casting method. The X-ray diffraction (XRD) and scanning electron microscopic (SEM) studies revealed the formation of intercalated and exfoliated OMMT structures in the prepared composites. The detailed optical characterization of these HPNC films is carried out with measurements of absorbance spectra by employing a dual beam ultraviolet-visible (UV-Vis) spectrophotometer of wavelength range 200–800 nm. The varying amounts of dispersed OMMT into the PVDF/PMMA blend matrix leads to a gradual decrease in the direct energy band gap of the host matrix from 5.12 eV to 4.54 eV and also shows semiconductive characteristics of 3.83 eV wide band gap at higher nanofiller concentrations. The band gap values of these HPNC films are compared and discussed with other composites of different polymer blend matrices dispersed with a variety of nanofillers. The increase of OMMT concentrations enhanced the range of refractive index (1.85–2.65), extinction coefficient (1.14–10.69 × 10–4), optical range dielectric permittivity (3.44–7.07), and optical conductivity (1.32–17.14 × 1011 s−1) of these HPNC films, at a fixed wavelength of 500 nm, which further changes largely with the alteration in wavelength of incident photons. The nanofiller concentration controllable optical parameters of these PVDF/PMMA/OMMT based HPNCs reveal that they could be promising performance and multipurpose optical materials in the advances of futuristic flexible-type optoelectronic devices.

Enhancement of the hardness and impact strength of epoxy-based metal oxide nanocomposites through hybridization

In this study, hybrid polymer nanocomposites were produced by combining epoxy (EP) with varying amounts of zirconia (ZrO[Formula: see text] and yttria (Y2O[Formula: see text] nanoparticles (NPs), reinforced with multi-walled carbon nanotube (MWCNT) and glass fiber (GF). The objective of this study is to develop and examine the performance of EP nanocomposites through hybridization; for this purpose, hardness and impact tests were conducted in accordance with American Society for Testing and Materials (ASTM) standards. Different sets were produced to investigate the effect of used fillers, including EP/ZrO2, EP/Y2O3, EP/MWCNT, EP/GF, EP/ZrO2/Y2O3, EP/MWCNT/ZrO2/Y2O3, and EP/MWCNT/GF/ZrO2/Y2O3. All findings were compared with the net EP sample. The results showed that the EP nanocomposite samples with low NPs content exhibit much higher mechanical performance than net EP. Furthermore, the additions of MWCNT and GF separately at 0.1 and 0.06[Formula: see text]wt.% have increased the impact strength, respectively, to 165.2% and 338.8%, compared with pure EP. As a result, the presence of MWCNTs and GF in the EP-based nanocomposite matrix could make the product both stronger and tougher.

Hybrid gold/graphene oxide reinforced polycaprolactone nanocomposite for biomedical applications

Biocompatible nanohybrids, with multiple functionalities, incorporated into a polymeric system aid the design of bioresorbable nanocomposites for biomedical applications. Herein, we report the effectual inclusion of graphene oxide anchored with gold nanostructures (GO-Au) into polycaprolactone (PCL) matrix with distinguished Physico-chemical and biological characteristics. Successful adhesion of the synthesized, multi-shaped Au NPs over graphene sheet surface was confirmed by the results obtained from SEM, HR-TEM, EDAX, XRD, XPS, F-TIR, and Raman techniques. In addition, the optical attributes of the nanohybrid were explored by employing the UV–vis and PL spectral techniques. The hemolysis test conducted for the nanohybrid further confirms its biocompatibility. Subsequently, the introduction of these hybrid nanostructures to the PCL system revealed a giant enrichment in the hydrophilicity, mechanical stability as well as antibacterial activity of the polymeric nanocomposite. Further, notable biodegradation, biomineralization, ALP activity, cell viability, and cell adhesive nature of the hybrid polymer nanocomposite show its potential role in bone tissue engineering. Thus, the current work presents a strategic design for fabricating a bioresorbable nanocomposite with substantial influence on bioactivity which makes them a suitable candidate for biomedical applications, particularly for bone tissue engineering.

Exploring Effects of Graphene and Carbon Nanotubes on Rheology and Flow Instability for Designing Printable Polymer Nanocomposites.

Nowadays, a strong demand exists for printable materials with multifunctionality and proper rheological properties to overcome the limitations to deposit layer-by-layer in additive extrusion. The present study discusses rheological properties related to the microstructure of hybrid poly (lactic) acid (PLA) nanocomposites filled with graphene nanoplatelets (GNP) and multiwall carbon nanotubes (MWCNT) to produce multifunctional filament for 3D printing. The alignment and slip effects of 2D-nanoplatelets in the shear-thinning flow are compared with the strong reinforcement effects of entangled 1D-nanotubes, which govern the printability of nanocomposites at high filler contents. The mechanism of reinforcement is related to the network connectivity of nanofillers and interfacial interactions. The measured shear stress by a plate-plate rheometer of PLA, 1.5% and 9% GNP/PLA and MWCNT/PLA shows an instability for high shear rates, which is expressed as shear banding. A rheological complex model consisting of the Herschel-Bulkley model and banding stress is proposed for all considered materials. On this basis, the flow in the nozzle tube of a 3D printer is studied by a simple analytical model. The flow region is separated into three different regions in the tube, which match their boundaries. The present model gives an insight into the flow structure and better explains the reasons for printing enhancement. Experimental and modeling parameters are explored in designing printable hybrid polymer nanocomposites with added functionality.

Thermal and dielectric properties of PVDF/PEO/SiO2 nanodielectrics for flexible radioelectronic device technologies

Hybrid polymer nanocomposites (HPNCs) are innovative multifunctional materials, which are developed and intensively studied for their uses in the rapid evolution of flexible and lightweight device technologies. Accordingly, to contribute in this area, thermal properties of the crystal phases and the broadband radio frequencies dielectric dispersion and relaxation behaviour of the HPNC films based on poly(vinylidene fluoride) (PVDF)/poly(ethylene oxide) (PEO)/silica (SiO2) are formulated and studied by employing differential scanning calorimeter (DSC) and impedance/material analyzer (IMA). DSC thermograms of these semicrystalline HPNCs explained the wide range alteration in the crystals melting temperature of PVDF (153–167 ​°C) and PEO (59–72 ​°C) and the total degree of crystallinity (4–87%) with varying compositional ratio over the entire range of the PVDF/PEO blend host matrix and the dispersed amount of amorphous SiO2 nanomaterial up to 15 ​wt%. The dielectric dispersion behaviour of these HPNCs, at 20 ​°C, confirmed a non-linear decrease in permittivity with the increase of applied radio wave electric field frequency from 1 ​MHz to 1 ​GHz, which lies in the range of 6 to 2. At a fixed frequency, dielectric permittivity values exhibited an uneven variation with the increase of SiO2 amount and also the modification in the composition of polymer blend matrix in these composites. The analysis of dielectric loss spectra and relaxation processes revealed that these are low loss dielectrics and the presence of SiO2 nanoparticles in the polymer blend matrix impedes the chain segmental dynamics and the dipole reorientation. The electrical conductivity of these HPNCs enhanced in the range of 10−8 to 10−4 ​S/cm with the increase in frequency but it changed anomalously when the constituent amounts of the formulated composites are varied. The polymer crystals thermal properties and the dielectric and electrical conductivity dispersion behaviour of these materials are demonstrated with the consideration of polymer-polymer and polymer-nanoparticle hybrid interfaces and interactions. The experimental results evidenced the behaviour of PVDF/PEO/SiO2 films as tunable nanodielectrics with their compositions and could be used as insulator and dielectric substrate materials in the advances of flexible radioelectronics and energy storage devices.

Dielectric and electromagnetic interference shielding properties of nano‐silicon carbide/montmorillonite and graphene nanoplatelets filled polyvinylidene fluoride/poly(3,4‐ethylenedioxythiophene)‐block‐poly(ethylene glycol) blend nanocomposites

AbstractHerein, hybrid polymer nanocomposite films comprising polyvinylidene fluoride (PVDF) and poly(3,4‐ethylenedioxythiophene)‐block‐poly(ethylene glycol) (PEDOT‐block‐PEG) as matrices and silicon carbide nanoparticles (SiC NPs), montmorillonite (MMT) nanoclay, and graphene nanoplatelets (GNPs) as nanofillers were fabricated by solution casting. The structural, morphological, and thermal characteristics of the nanocomposite films were assessed using Fourier transform infrared spectroscopy (FTIR), x‐ray diffraction (XRD), scanning electron microscope (SEM), thermogravimetric analyzer (TGA), and differential scanning calorimetry (DSC). The SEM results show the homogeneous distribution of nanofillers within the polymer matrix. The dielectric behavior and electromagnetic interference shielding efficiency (EMI SE) of the nanocomposites were also analyzed. The maximum dielectric constant (ε) and dielectric loss (tan δ) obtained are 47.77 and 12.08, respectively, at lower frequency (50 Hz, 150°C). The maximum EMI SE was observed to be 16.8 dB in the Ku‐band region (12–18 GHz) for the nanocomposites with 20 wt% SiC, 8 wt% MMT, and 2 wt% GNPs loading. The EMI shielding was found to be absorption dominant and originated from the formation of a conductive network between hybrid nanofillers within the PVDF/PEDOT‐block‐PEG blend thereby improving the EMI SE values. These results suggest that PVDF/PEDOT‐block‐PEG/SiC/MMT/GNPs nanocomposites can be used as an efficient EMI shielding material.
