Abstract
(EN)
Disclosed is a ferroelectric material (12) and methods for its use in capacitors. The ferroelectric material (12) comprises a polymer blend comprising a ferroelectric polymer (12a) and a dielectric polymer (12b) having a low dielectric constant. The dielectric polymer (12b) can phase separate from the ferroelectric polymer (12a) such that a plurality of separated regions (12b) are formed within the ferroelectric polymer (12a). The ferroelectric material (12) is disposed between two electrodes (11) and (13). The plurality of regions (12b) act as charge-trap regions to store charge and prevent charge carriers to move freely throughout the ferroelectric polymer (12a).

L'invention concerne un matériau ferroélectrique (12) et des procédés pour son utilisation dans des condensateurs. Le matériau ferroélectrique (12) comprend un mélange de polymères comprenant un polymère ferroélectrique (12a) et un polymère diélectrique (12b) ayant une faible constante diélectrique. Le polymère diélectrique (12b) peut se séparer en phases du polymère ferroélectrique (12a) de telle sorte qu'une pluralité de régions séparées (12b) sont formées à l'intérieur du polymère ferroélectrique (12a). Le matériau ferroélectrique (12) est disposé entre deux électrodes (11) et (13). La pluralité de régions (12b) servent de régions de piégeage de charge pour stocker la charge, et empêchent les porteurs de charge de se déplacer librement à travers le polymère ferroélectrique (12a).
