Title
(DE) MATERIALIEN MIT STEUERBAREM VERNETZUNGSGRAD
(EN) MATERIALS HAVING CONTROLABLE DEGREE OF CROSSLINKING
(FR) MATÉRIAUX AYANT UN DEGRÉ DE RÉTICULATION CONTROLABLE
Abstract
(DE) Die vorliegende Erfindung betrifft neuartige Materialien, die mittels zwei unterschiedlicher Vernetzungsmechanismen vernetzt werden können, wobei es sich bei dem ersten Vernetzungsmechanismus um eine irreversible Vernetzung handelt. Bei dem zweiten Vernetzungsmechanismus handelt es sich um einen thermoreversiblen Mechanismus. Durch diese thermoreversible Veränderung der Netzbogenlänge können Eigenschaften des vernetzen Materials entscheidend verändert und gesteuert werden, dies beinhaltet u.a. Flexibilität, Elastizität und weitere mechanische Eigenschaften, aber auch chemische Eigenschaften, die Gasund Dampfpermeabilität und Speichervermögen des Netzwerks. Auf diese Weise könnten z.B. Energieträger wie Brennstoffe gespeichert werden.
(EN) The present invention relates to novel materials which can be crosslinked by means of two different crosslinking mechanisms, where the first crosslinking mechanism is an irreversible crosslinking. The second crosslinking mechanism is a thermoreversible mechanism. Properties of the crosslinked material, including, inter alia, flexibility, elasticity and further mechanical properties but also chemical properties, the gas and vapour permeability and storage capacity of the network, can be decisively changed and controlled by means of this thermoreversible change in the internode distance. Energy carriers such as fuels, for example, could be stored in this way.
(FR) L'invention concerne de nouveaux matériaux qui peuvent être réticulés à l'aide de deux mécanismes de réticulation différents, s'agissant dans le cas du premier mécanisme de réticulation d'une réticulation irréversible. Dans le cas du deuxième mécanisme de réticulation, il s'agit d'un mécanisme thermoréversible. Grâce à cette modification thermoréversible de la longueur de chaîne du réseau, on peut modifier radicalement les propriétés du matériau réticulé et les déterminer, ceci comprenant entre autres la flexibilité, l'élasticité et d'autres propriétés mécaniques, mais également les propriétés chimiques, la perméabilité aux gaz et à la vapeur et les facultés de stockage du réseau. De cette façon, des porteurs d'énergie comme des carburants pourraient être stockés.
