Investigations on the mechanisms of ionic conductivity in PEO-PU/PAN semi-interpenetrating polymer network-salt complex polymer electrolytes: An impedance spectroscopy study

Article Abstract:

A comprehensive study on the correlated ion transport mechanisms contributing to the overall conductivity behavior in a new class of poly/(ethylene oxide)-polyurethane/polyacrylonitrile (PEO-PU/PAN) semi-interpenetrating polymer networks (semi-IPNs)-salt complex polymer electrolytes is presented. Analysis of the complex plane and spectroscopic plots indicates the presence of two microscopic phases corresponding to the PEO-PU and PAN domains.

Influence of ionic content in polyurethane ionomer solutions

Article Abstract:

The effect of an increase in the ionic content of the ionomer is explored. It is found that sufficiently high ionic content can cause dissolution of the ionomer as a whole, resulting in a different kind of solution behavior. Combined static and dynamic light scattering experiments are applied to model ionomers to better understand the solution structure that results in characteristic polyelectrolyte behavior.

Shear and dilational surface rheology of oppositely charged polyelectrolyte/surfactant microgels adsorbed at the air-water interface. Influence on foam stability

Article Abstract:

The surface dilational and shear properties of adsorbed layers of oppositely charged polymer-surfactant complexes at the air-water interface are measured using the oscillating drop method and the interfacial stress rheometer (ISR). The results reveal that the shear surface moduli G' and G" exhibit a maximum at a molar ratio of polymer monomers and surfactant in solution equal to one.
