Structure of new mixed conducting alternate copolymers

The studied materials are used as electrodes in solid-state batteries and e lectrochromic devices. They are constituted of alternating redox aromatic d i-imides and polyethylene oxide (PEO) ion-conducting segments whose length is controlled, Their electroactive properties should be partly correlated w ith structural features. It is shown that, concerning the semi-crystalline samples, the ratio of lengths between their two components is driving the o verall conformation of chains and thus, the way the system is crystallizing towards different condensed phases. This paper is dealing with the modelin g and description of these 3-dimensional structures.
