“…As the graphene planes and DMSO come close to each other, the π bonding occurs between carbon and DMSO in the perpendicular direction. With an increase in temperature, DMSO evaporates between graphene planes; thus, the planes condense and get closer to each other, leading to charge transportation [27,39]. It is seen that an increase in the graphene content reduces the surface resistance, while it increases the thermal stability of the composite cotton [49].…”

Efficient energy storage is becoming a serious niche area nowadays due to exponential growth in energy consumption. Different approaches have been developed and implemented to improve the performance of the devices, in which improving conductivity is a major issue. In the present work, cotton fabric was converted into a conductive material by incorporating graphene, using the Layer-by-Layer (LBL) method, followed by heating at 100 °C. The electrical conductivity of the cotton using different concentrations of graphene was studied. The graphene-coated cotton, at the 17th layer, with a concentration of 168.36 wt.% resulted in a surface resistance of 0.644 Ω/sq and retained the maximum resistance even after two months. Scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy analysis (EDX) were employed to comprehend the surface morphology and elemental compositions. Fourier transform infrared (FTIR) spectroscopy, UV-vis absorption, and X-ray diffraction (XRD) were used to determine the structural analysis, which revealed a good dispersion of graphene in the cotton samples obtained through dimethyl sulfoxide (DMSO) doping, which reduced the ripple of the cotton. The cotton fabric treated with graphene was thermally stable, as shown through thermal analysis. From the results obtained, it is evident that graphene-treated cotton fabric materials show tremendous potential for use in smart textiles and also as protective clothing.

“…They help to reduce the side effects of dendritic growth on sodium (Na) anode and their inert nature minimizes leakage problems. Furthermore, SPEs also have advantages in terms of decreased contact resistance, increased mechanical strength, flexibility, adaptability, lightweight design, and cost-effectiveness [2][3][4][5][6]. SPEs perform the dual function of separators and electrolytes.…”

This paper focuses on the preparation, characterization and dielectric studies of the flexible and free-standing solid polymer electrolyte membranes based on PEO + PVDF-HFP complexed with NaPF6 by the solution casting technique. The X-ray diffraction, Differential scanning calorimetry techniques were employed to analyse the structural properties and melting temperatures of the prepared solid polymer electrolyte membranes. In this study, we have explored the impact of polymer blending. The weight percentages of PEO and PVDF-HFP were systematically varied, while keeping the NaPF6 weight percentage constant. The impedance spectra of the prepared solid polymer electrolyte membranes are recorded using the N4L-PSM1735 Impedance Analysis Interface across a frequency range spanning from 1 Hz to 30 MHz. The obtained impedance spectroscopy data facilitated the determination of bulk resistance (R b ) and enabled an in-depth exploration of the dielectric and electrical modulus characteristics of the prepared solid polymer electrolyte membranes. Ionic conductivity values are derived through the analysis of bulk resistance (R b ) measurements. The most notable ionic conductivity value of 5.418x10−7 S/cm at room temperature was achieved with the solid polymer electrolyte membrane 70wt%PEO+30wt%PVDF-HFP+3wt%NaPF6. In this study, the solid polymer electrolyte membrane comprising 70wt%PEO, 30wt%PVDF-HFP, and 3wt%NaPF6 emerged as the optimum conducting composition.

“…Its excellent processability and film-forming ability make PVA films easy to fabricate by casting or blow extrusion. − To enhance the thermal and barrier properties of PVA, nanoparticles are often employed. Nanotechnology, which involves engineering materials with at least one dimension in the nano range (10–100 nm), offers a way to gain new characteristics attributed to nanometer dimensions. One of the best and fastest routes to apply nanotechnology is by creating nanocomposites.…”

Poly(vinyl alcohol) (PVA), a naturally occurring and rapidly decomposing polymer, has gained significant attention in recent studies for its potential use in pollution preventive materials. Its costeffectiveness and ease of availability as well as simple processing make it a suitable material for various applications. However, the only concern about PVA's applicability to various applications is its hydrophilic nature. To address this limitation, PVA-based nanocomposites can be created by incorporating inorganic fillers such as graphene (G). Graphene is a two-dimensional carbon crystal with a single atom-layer structure and has become a popular choice as a nanomaterial due to its outstanding properties. In this study, we present a simple and environmentally friendly solution processing technique to fabricate PVA and graphene-based nanocomposite films. The resulting composite films showed noticeable improvement in barrier properties against moisture, oxygen, heat, and mechanical failures. The improvement of the characteristic properties is attributed to the uniform dispersion of graphene in the PVA matrix as shown in the SEM image. The addition of graphene leads to a decrease in water vapor transmission rate (WVTR) by 79% and around 90% for the oxygen transmission rate (OTR) as compared to pristine PVA films. Notably, incorporating just 0.5 vol % of graphene results in an OTR value of as low as 0.7 cm m −2 day −1 bar −1 , making it highly suitable packaging applications. The films also exhibit remarkable flexibility and retained almost the same WVTR values even after going through tough bending cycles of more than 2000 at a bending radius of 2.5 cm. Overall, PVA/G nanocomposite films offer promising potential for PVA/G composite films for various attractive pollution prevention (such as corrosion resistant coatings) and packaging applications.
