Characterization and Conductivities of Polyphosphazene-Iodine Complexes
Abstract
The preparation of ionically conducting solids is of broad fundamental interest. These materials have applications in solid-state electrochemical devices. Polymer-based complexes possess several advantages over semi-crystalline solids, and these advantages include ease of chemical modification and processability. Recent work has shown that high bulk conductivities at ambient temperature can be obtained for etheric polymer complexes that contain polyiodides. Iodine forms charge-transfer complexes with a wide variety of polymers, or it may disproportionate to form polyiodides. Also, conjugated polymers such as polyacetylene become electronically conducting following reaction with many oxidizing agents, including I2. However, a number of monomers and non-conjugated polymers also form stable, highly conductive complexes with iodine. Examples include poly(vinylpyridine) and poly(alkylsulfides).
