Structure of new mixed conducting alternate copolymers

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