Title
(EN) ELECTROCHEMICALLY DEGRADABLE POLYMERS
(FR) POLYMÈRES ÉLECTROCHIMIQUEMENT DÉGRADABLES
Abstract
(EN) The present invention discloses polymeric materials that incorporate a modified quinone core structure, which serves as a cross-linking agent or a monomeric unit within the polymer. These polymers can be efficiently degraded through electrochemical reduction. Moreover, the polymer's degradation rate can be tuned by making predictable structural changes. The disclosed polymer compositions can be used to produce electrochemically degradable commodities such as adhesives, concrete and the like.
(FR) La présente invention concerne des matières polymériques qui incorporent une structure de cœur quinone modifiée, qui sert d'agent de réticulation ou d'unité monomérique à l'intérieur du polymère. Ces polymères peuvent être dégradés de façon efficace par une réduction électrochimique. De plus, la vitesse de dégradation du polymère peut être adaptée par la réalisation de changements structuraux prédictibles. Les compositions de polymère selon l'invention peuvent être utilisées pour fabriquer des produits de base électrochimiquement dégradables tels que des adhésifs, du ciment et similaires.
