Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung eines Polymerkomposits, umfassend elektrisch leitfähige Nanopartikel sowie eine Polymermatrix,die ein oder mehrere Polymere enthält,wobei das Verfahren die folgenden Schritte aufweist: (1) Bereitstellen von Agglomeraten (10) der elektrisch leitfähigen Partikel; (2) Einpacken der Agglomerate (10) in eine flexible, semipermeable Membran (20), so dass die Agglomerate (10) vollständig umhüllt wird; (3) Tränken der aus Schritt (2) erhaltenen eingepackten Agglomerate (10) mit einem oder mehreren Polymeren, das/die vorzugsweise gelöst in ein oder mehreren Lösungsmitteln vorliegen; (4) Pressen und bevorzugterweise anschließendes Aushärten, insbesondere unter Druck, der aus Schritt (3) erhaltenen Agglomerate (10); und (5) Zweckmäßigerweise entfernen der Membran (20) unter Erhalt des Polymerkomposits. Gegenstand der Erfindung sind auch die mit dem Verfahren erhaltenen Polymerkomposite sowie eine Vorrichtung zur Durchführung des Verfahrens. Die hergestellten Polymerkomposite liefern einen besonders hohen Füllgrad an Nanopartikeln und damit eine überaus hohe elektrische Leitfähigkeit der mit Nanopartikeln ausgerüsteten Polymere.
(EN)
The invention relates to a process for the production of a polymer composite, comprising electrically conductive nanoparticles, and also a polymer matrix which contains one or more polymers, where the process has the following steps: (1) provision of agglomerates (10) of the electrically conductive particles; (2) packing the agglomerates (10) into a flexible, semipermeable membrane (20) in such a way that the agglomerates (10) are entirely enclosed; (3) saturation of the packed agglomerates (10) obtained from step (2) with one or more polymers preferably dissolved in one or more solvents; (4) pressing and preferably subsequent hardening, more particularly under pressure, of the agglomerates (10) obtained from step (3); and (5) advantageously removing the membrane (20) to give the polymer composite. The invention also relates to the polymer composites obtained by the process and to a device for carrying out the process. The resultant polymer composites provide a particularly high nanoparticle fill level and thus provide extremely high electrical conductivity of the polymers equipped with nanoparticles.

L'invention concerne un procédé de fabrication d'un composite polymère comprenant des nanoparticules électroconductrices ainsi qu'une matrice polymère qui contient un ou plusieurs polymères, le procédé comprenant les étapes suivantes: (1) préparer des agglomérats (10) des particules électroconductrices; (2) emballer les agglomérats (10) dans une membrane (20) flexible et semi-perméable de telle manière que les agglomérats (10) soient totalement enveloppés; (3) imprégner les agglomérats (10) emballés obtenus à l'étape (2) avec un ou plusieurs polymères qui est/sont de préférence dissous dans un ou plusieurs solvants; (4) presser et de préférence durcir ensuite, en particulier sous pression, les agglomérats (10) obtenus à l'étape (3); et (5) éliminer avantageusement la membrane (20) et obtenir le composite polymère. L'invention concerne également les composites polymères obtenus à l'aide du procédé ainsi qu'un dispositif pour mettre en œuvre le procédé. Les composites polymères fabriqués fournissent un degré de remplissage en nanoparticules particulièrement élevé et donc une conductibilité électrique très élevée des polymères équipés de nanoparticules.
