摘要：

We report the analysis of comb-like polymers by solid-state NMR. The polymers were previously evaluated as solid-polymer-electrolytes (SPE) for lithium-polymer-metal batteries that have suitable ionic conductivity at 60 degrees C. We propose to develop a correlation between C-13 solid-state NMR measurements and phase segregation. C-13 solid-state NMR is a perfect tool for differentiating polymer phases with fast or slow motions. Li-7 was used to monitor the motion of lithium ions in the polymer, and activation energies were calculated.
