Thecombinationofthephosphazinebackbone (to yield low glass transition temperature and mobility) with oligo ether side chains (to provide complexation to drive the System thermodynamically, towards the elastomeric conductor) was a triumph of imagination and créative solid-state materials. Shriver's most récent investigation—of polymer-mixed conductors in which both electronic charge and ionic charge are transferred—présents one of the most challenging problems in understanding how charge transport occurs in disordered sysIMIÏÏISI tems with mixed conductivity.
