Electronic and ionic charge carriers are added to crystallites first during electrochemical charging when the local environment of the polymer is optimized through side chain engineering. During these processes, polymer backbones planarize to form percolating networks for efficient charge transport. Surprisingly, the associated microstructural changes of the polymer are highly reversible when high densities are avoided. Intrigued? Read more about our article here.
Below you find a video about the electrochemical charging and discharging of the electrodes used to monitor the microstructure changes during electrochemical operation.
