Proton exchange membranes (PEMs) require high proton conductivity, stability, and durability for fuel cell applications. This study reports the synthesis of N-(2-acrylamido-2-methylpropane sulfonyl) chitosan (CSB) via Schiff base functionalization with 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and the…
View detailsThis work examined the effects of four plasticizers, glycerol (GLY), potassium phosphate (PHOS), polyethylene glycol (PEG), and soy lecithin (SL), on the structural, surface, thermal, optical, and mechanical properties of polyhydroxybutyrate (PHB) films. FTIR spectra demonstrated…
View detailsThis work presents the in-situ synthesis of zinc oxide (ZnO) nanoparticles in an oxidized polyvinyl alcohol (OPVA) matrix, which greatly enhances the final nanocomposites optical, mechanical, and proton conductive properties. Zinc acetate was used as a…
View detailsA novel solid biopolymer electrolyte (SBPE) hybrid was developed by directly linking oxidized polyvinyl alcohol (OPVA) with carboxymethyl cellulose (CMC) via ester formation. The CMC used in this study had a degree of substitution (DS) of…
View detailsThe scalable production of high-quality copper oxide (CuO) thin films remains challenging for semiconductor and gas sensor applications. This study presents an optimized aerosol droplet method (AMD) that enhances film uniformity and crystallinity through improved substrate…
View detailsAlternative proton exchange membranes (PEMs) with high proton conductivity must be fabricated at reasonable costs to qualify as commercially used proton-exchange membrane fuel cells (PEMFCs).
View detailsChitosan (CS) is a naturally occurring biopolymer that is readily accessible and widely used in various industrial applications. However, its low proton conductivity, particularly at elevated temperatures, poses challenges for its application as a proton exchange…
View detailsSulfonated poly (ether ether ketone) (SPEEK) has received substantial attention for its potential to improve the electrochemical behavior and thermomechanical capabilities of direct methanol fuel cells. This study examines how the integration by solution casting of…
View detailsOS (olive stones) are a type of lingo-cellulosic biomass that is generated as a by-product in the olive oil industry. In this investigation, the EC (extracted cellulose) from the olive stones was modified with CTAB (cetyl…
