Polymer electrolyte membrane (PEM) composed of polymer or blend is a vital element in PEM fuel cell that allows proton transport and serves as barrier between oxygen. Understanding the microscopic phase behavior blends very crucial to design alternative cost-effective proton-conducting materials. In this study, mesoscale morphologies Nafion/poly(1-vinyl-1,2,4-triazole) (Nafion-PVTri) Nafion/pol...

Composite polymer electrolyte (CPE) membranes, comprising poly (vinylidene fluoride) (PVdF)/poly (methyl methacrylate) (PMMA), BaTiO3 as ceramic filler and LiBF4 as the lithium salt were prepared using a solution casting technique. The prepared membranes were subjected to XRD, FT-IR, impedance spectroscopy and thermal stability studies. The incorporation of nanofiller greatly enhanced the ionic...

The rheological response of blends obtained from quaternized polysulfone and polyvinyl alcohol in N-methyl-2pyrrolidone as against structural peculiarity of polymers from the blend, composition of polymer mixtures, as well as the types of interactions were investigated. Results show that the variation of polyvinyl alcohol composition in the studied system determines changes of the rheological p...

Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...
