Název v původním jazyce

Dielectric spectroscopy of methacrylate polymers with pendant carbazole groups

Popis výsledku v původním jazyce

The thermal and electrical properties of methacrylate polymers with a charge transporting pendant carbazole ring were studied by varying the functional side groups. Dielectric spectroscopy indicates that as the distance between polymer backbone and pendant carbazole functional groups is increased, the rotation flexibility of the carbazole moiety is enhanced. Similar effect can be achieved by adding bulky functional groups on carbazole moiety. This is shown by decrease of activation energy and temperature for the onset of ring motion and resulted in polymer-based memristors using mechanism of conformation changes. These polymers exhibited memristive electrical characteristics (I–V), such as pinched hysteresis loop in the AC field when measured between 1–100 Hz.
