Poly-Electrolyte Polymer Brushes
It is shown using the mean field theory of Miklavic Marcelja that it should be possible for osmotic pressure due to the counterions associated with the two polyelectrolyte polymer brush coated surfaces (in the absence of excess salt) to support a reasonable load (i.e., about 105Pa)with the brushes held sufficiently far apart to prevent entanglement of polymers belonging to the two brushes, thus...
متن کاملConductivity and Structural Studies of Plasticized Polyacrylonitrile (PAN) – Lithium Triflate Polymer Electrolyte Films
The effect of different plasticizers on the properties of PAN– polymer electrolytes has been studied. Propylene carbonate (PC) and ethylene carbonate (EC) having different values of donor numbers, dielectric constant and viscosity have been used as plasticizers. The highest room temperature conductivity for the film in the PAN– system was 3.04 × 10-4 S cm-1. The highest room temperature conduct...
متن کاملEffect of interface on surface morphology and proton conduction of polymer electrolyte thin films.
To understand the relationship between surface morphology and proton conduction of polymer electrolyte thin films, perfluorinated ionomer Nafion® thin films were prepared on different substrates such as glassy carbon (GC), hydrophilic-GC (H-GC), and platinum (Pt) as models for the ionomer film within a catalyst layer. Atomic force microscopy coupled with an electrochemical (e-AFM) technique rev...
متن کاملSimultaneous measurements of conductivity and thickness for polymer electrolyte films: a simulation study
Planar cells provide an attractive alternative to traditional cylindrical cells for polymer electrolyte conductivity measurement as they not only allow sample quantity minimisation but also equilibration with vapour. They are also a key component in the parallel screening of combinatorially synthesised arrays of samples. A finite element simulation technique is used to calculate the complex cel...
متن کاملSupporting information Free Standing Graphene Oxide Paper: New Polymer Electrolyte for Polymer Electrolyte Fuel Cells
Graphite oxide was synthesized from natural flake graphite by the modified Hummers method. In brief, 200 mg of Graphite particles were immersed in Concentrated sulfuric acid (46 ml) and KMnO4 (6 g) was added slowly in small quantities in which temperature was maintained between the 0 and 5 c using an ice bath, after the complete oxidation of KMnO4, the mixture was heated to 37 c and kept at thi...
