Morphology of Ion-Containing Polymers: Correlations Between Structure, Dynamics, and Ion Conduction
Ion-containing polymers are of intense interest for applications in energy storage and conversion devices. The conductivities of these polymers are determined by both the ion mobility and the total number of mobile charge carriers, which in turn depend on the chemical structure and morphology. To rationally design ioncontaining polymers with high conductivity, a comprehensive understanding of t...
متن کاملMetal ion binding by pyridylethyl-containing polymers: experimental and theoretical study.
Binding of Cu(2+), Ni(2+) and Ag(+) ions to polyallylamine (PAA), polyethylenimine (PEI), poly(N-2-(2-pyridyl)ethylallylamine) (PEPAA), poly(N-2-(2-pyridyl)ethylethylenimine) (PEPEI), and N-2-(2-pyridyl)ethylchitosan (PEC) has been investigated using batch sorption experiments, spectrophotometric titration, ESR, and XPS to elucidate how the structure of polymer precursors affects the ion bindin...

Hydration and Proton Conductivity of Ionomers: The Model Case of Sulfonated Aromatic Polymers
*Correspondence: Philippe Knauth, Aix Marseille Université, Campus St Jérôme, 13397 Marseille, France e-mail: [email protected] The hydration of proton-conducting ionomers is described in terms of a simplified model, where only osmotic and elastic contributions to the Gibbs free energy of hydration are considered. Although only two physically meaningful parameters are used – the defor...
متن کاملDynamics of telechelic ionomers. Can polymers diffuse large distances without relaxing stress ?
We consider dynamics of entangled telechelic ionomers in the limit of strong association, where there are no free chain ends. Stress relaxation occu~s in such a system by an exchange between pairs of chain ends in the associated state. For complete relaxation of stress, an exchange went must take place on every entanglement strand. However, diffusion can occur on an arbitrarily shorter time sca...
