Gewöhnlich werden als natürliche Minerale Smektite, Talk, Karbonate, Glimmer, Silica oder Kaolinit/Halloysit eingesetzt, wobei durch diverse Aufbereitungsverfahren die Kornverfeinerung (bis ca. 100 nm) erreicht bzw. durch Desagglomeration/Exfoliation, insbesondere ausgewählter Tonminerale, die Nanoskalierung erzielt wird.Usually are natural minerals smectites, talc, carbonates, Mica, silica or kaolinite / halloysite are used, passing through various processing methods grain refinement (up to approx. 100 nm) achieved or by deagglomeration / exfoliation, in particular selected Clay minerals, the nanoscale is achieved.
Diese natürlichen Nanopartikel stehen als preisgünstige funktionelle Fülleralternativen zu synthetischen Nanopartikeln (Kohlenstoff-Nanotubes-CNT, Nano-Metallpartikel – wie Silber oder Titanoxid) für diverse Anwendungen zur Verfügung.These Natural nanoparticles are considered cheap functional filler alternatives to synthetic nanoparticles (Carbon nanotube CNT, nano-metal particles - like silver or titanium oxide) for various applications.
Neben der äußeren nanoskalierten Morphologie weisen einige der natürlichen Minerale nanoskalierte innere Porenräume aus, die für diverse Anwendungen (z. B. drug delivery) von Interesse sind. Dies betrifft Diatomite, Zeolithe und Halloysite, wobei die Durchmesser der Nanoporen zwischen 0,3 und ca. 20 nm schwanken.Next the outer nanoscale morphology point some of the natural minerals have nano-scaled internal pore spaces out for various applications (eg drug delivery) are of interest. This concerns diatomites, zeolites and halloysites, wherein the diameters of the nanopores fluctuate between 0.3 and about 20 nm.

Aufgabe der ErfindungObject of the invention
Die Aufgabe der Erfindung bestand darin die im Stand der Technik genannten Nachteile der Nanopartikel zu beseitigen und damit neue Anwendungsmöglichkeiten bereitzustellen.The The object of the invention was that mentioned in the prior art Disadvantages of nanoparticles eliminate and thus new applications provide.
Lösung der AufgabeSolution of the task
Die Aufgabe wurde gemäß den Merkmalen der Patentansprüche gelöst. Erfindungsgemäß wurden ausgewählte natürliche Mineralprodukte mit nanoskaligen Eigenschaften (Primärmorphologie und Nanoporen) hergestellt, die durch Behandlung mit Plasmen, vorzugsweise Niedertemperaturplasmen, erhalten wurden.The Task has been in accordance with the features of the claims solved. Selected according to the invention natural mineral products with nanoscale properties (Primary morphology and nanopores) produced by Treatment with plasmas, preferably low temperature plasmas were.
Überraschenderweise hat sich herausgestellt, dass dabei eine Zerstörung der Kristallstruktur und eingelagerter Wassermoleküle nicht eintritt, die natürliche mikrobiologische Keimbelastung reduziert wird und die Dispergierbarkeit in diversen Matrixsystemen durch Hydrophilierung, Hydrophobierung oder Beschichtung verbessert wird.Surprisingly has been found to be a destruction of the Crystal structure and embedded water molecules not occurs, the natural microbial germ load is reduced and the dispersibility in various matrix systems improved by hydrophilization, hydrophobing or coating becomes.
Damit ist einerseits eine optimale Anpassung an die Matrix in Verbund- und Schichtsystemen möglich, was mit höherem Füllungsgrad und besserer Haftung und Dispergierbarkeit verbunden ist und andererseits kann eine verbesserte Spurenelementdotierung (z. B. In, Se) oder Wirkstoffdotierung erfolgen, was für spezielle Life-Science-Produkte (Kosmetik, Medizinprodukte, Pharmaka, Tierarzneimittel und Medizinalfutter) bedeutsam ist.In order to On the one hand, optimal adaptation to the matrix in composite and layer systems possible, what with higher degree of filling and better adhesion and dispersibility, and on the other hand can be an improved trace element doping (eg In, Se) or Drug doping done, which is special for life science products (Cosmetics, medical devices, pharmaceuticals, veterinary drugs and medicated feed) is significant.
Die erfindungsgemäßen plasmamodifizierten natürlichen Minerale mit nanoskaligen Eigenschaften, wie Halloysit, eignen sich für den Einbau in Verbund- und Schichtsysteme. Halloysit besitzt ein hohes Aspektverhältnis und ist damit für den Aufbau von netzartigen Strukturen geeignet. Weiterhin besitzen die Halloysit-Partikel eine röhrenförmige Morphologie. Damit können im Nanoporenraum, z. B. pharmazeutische Wirkstoffe oder Spurenelemente angelagert werden, die dann nach der Aufnahme in den menschlichen oder tierischen Körper verzögert wieder freigesetzt werden. Voraussetzung für die Verwendung des Halloysits in diesen Anwendungen ist eine Plasmabehandlung, die einerseits eine vollständige und homogene Oberflächenmodifizierung (Sauerstoff- oder Stickstoff-Funktionalisierung und Beschichtung mit kohlenstoffhaltigen Schichten) realisiert und andererseits zu keinen Veränderungen in der Struktur und der Form der Partikel fuhrt. Erst durch einen derartig oberflächenbehandelten Halloysit kann optimal in einer Matrix dispergiert werden bzw. es können Wirkstoffe oder Spurenelemente angelagert werden. Für eine derartige Oberflächenbehandlung wurde ein Plasmaverfahren bereitgestellt, bei dem Halloysitpulver z. B. als Haufwerk mit einer Schichtdicke von mindestens 5 mm auf einer Schale oder in einer Trommel liegt und durch mechanische Aktivierung ständig bewegt wird, so dass die einzelnen Teilchen nur zeitweise mit dem Plasma in Berührung kommen. Dadurch wird gewährleistet, dass der Energieeintrag auf die einzelnen Teilchen nicht kontinuierlich, sondern diskontinuierlich erfolgt und somit eine Schädigung vermieden werden kann. Zusätzlich kann hierfür auch ein gepulstes Plasma eingesetzt werden.The plasma-modified natural minerals according to the invention with nanoscale properties, such as halloysite, are suitable for incorporation in composite and layer systems. Halloysite has a high aspect ratio and is therefore suitable for the construction of net-like structures. Furthermore, the halloysite particles have a tubular morphology. This can be in the nanopore space, z. As pharmaceutical agents or trace elements are attached, which are then released after being absorbed into the human or animal body delayed. A prerequisite for the use of the halloysite in these applications is a plasma treatment, which realizes on the one hand a complete and homogeneous surface modification (oxygen or nitrogen functionalization and coating with carbonaceous layers) and on the other hand leads to no changes in the structure and shape of the particles. Only by such a surface-treated Halloysit can be optimally dispersed in a matrix or it can be added active ingredients or trace elements. For such a surface treatment, a plasma process was provided in which Halloysitpulver z. B. as a debris with a layer thickness of at least 5 mm on a dish or in a drum and is constantly moved by mechanical activation, so that the individual particles come into contact only temporarily with the plasma. This ensures that the energy input to the individual particles is not continuous, but discontinuous and thus damage can be avoided. In addition, a pulsed plasma can also be used for this purpose.
Die Erfindung soll anhand eines Beispiels näher beschrieben werden, ohne sie auf dieses Beispiel zu begrenzen.The Invention will be described in more detail by way of example without limiting it to this example.
