“…Notably, the MMT modification to the O-MMT results in a shift of 2θ from higher to lower values, accompanied by enhancement of the interlayer distance for the O-MMT, ( d = 18.6 Å) relative to pure MMT form ( d = 12.1 Å), which can be described using Bragg’s equation and confirms the induction of silane within MMT spaces.

High-temperature proton-exchange membrane fuel cells (HT-PEMFCs) have indeed emerged as highly efficient devices for energy conversion with numerous applications, ranging from portable electronics to transportation. The development of advanced electrolyte materials is imperative to enhance the PEMFCs' stability and performance. Herein, we use sulfonated polyvinyl chloride (SPVC) and 2,5-benzimidazole-modified montmorillonite (AB-MMT) to create a series of novel composite electrolytes for PEMFC via a solution-casting method. PVC, well known for its excellent film-forming properties, is combined with modified MMT, a natural inorganic clay with a high surface area and ion-exchange capability (IEC). The composite polymer electrolyte membranes (PEMs) are further doped with phosphoric acid (PA) at varying concentrations. The structural, morphological, and electrochemical properties of prepared PEMs are systematically analyzed using FTIR, XRD, SEM, and impedance spectroscopies. The effect of PA on PEMs in terms of water uptake, mechanical and chemical stability, and ionic conductivity is also analyzed. The synergy between SPVC and AB-MMT creates a favorable microenvironment for ion transport within the membrane, contributing to enhanced PEMFC performance. The experimental results demonstrate that 10SBZMP exhibits a substantial increase in ionic conductivity, i.e., 0.069 at 150 °C and RH 98% with a power density of 0.252 W/cm 2 . The development of advanced materials like these paves the way for more efficient and reliable fuel-cell technologies, contributing to the sustainable energy landscape of the future.

“…Our research focuses on using CNP-filled poly(vinyl chloride)(PVC) nanocomposites (PVC)/CNPs) as interfacial electron transfer layers in SC-PMSs [21,22]. We chose PVC as the host matrix material because of its many valuable properties, such as low cost, good processability, chemical stability, and low flammability [23]. PVC is an electrically insulating polymer (with a film conductivity on the order of 10 −14 S/m) [24].…”

Polymer nanocomposites filled with carbon nanoparticles (CNPs) are a hot topic in materials science. This article discusses the current research on the use of these materials as interfacial electron transfer films for solid contact potentiometric membrane sensors (SC-PMSs). The results of a comparative study of plasticized poly (vinyl chloride) (pPVC) matrices modified with single-walled carbon nanotubes (SWCNTs), fullerenes-C60, and their hybrid ensemble (SWCNTs-C60) are reported. The morphological characteristics and electrical conductivity of the prepared nanostructured composite films are reported. It was found that the specific electrical conductivity of the pPVC/SWCNTs-C60 polymer film was higher than that of pPVC filled with individual nanocomponents. The effectiveness of this composite material as an electron transfer film in a new potentiometric membrane sensor for detecting phenylpyruvic acid (in anionic form) was demonstrated. Screening for this metabolic product of phenylalanine in body fluids is of significant diagnostic interest in phenylketonuria (dementia), viral hepatitis, and alcoholism. The developed sensor showed a stable and fast Nernstian response for phenylpyruvate ions in aqueous solutions over the wide linear concentration range of 5 × 10−7–1 × 10−3 M, with a detection limit of 10−7.2 M.
