Title (EN) WATER-BASED PRODUCTION OF METAL-OXIDE AND METAL NANOFIBERS
(FR) FABRICATION À BASE D'EAU DE NANOFIBRES D'OXYDE DE MÉTAL ET DE MÉTAL
(DE) WASSERBASIERTE HERSTELLUNG VON METALLOXID- UND METALL-NANOFASERN
Abstract:
(EN) The invention relates to a method for producing metal-oxide fibers or metal fibers having a diameter in the range of 0.1 to 999 nm by electrospinning a solution containing one or more polymers, one or more metallic salts, one or more complexing agents, and a solvent, comprising the following steps: (a) providing a solution containing one or more polymers, one or more metallic salts, one or more complexing agents, and a solvent, wherein the solution has a water content of at least 50 wt%, (b) electrospinning the solution, and (c) removing the polymer.
(FR) L'invention concerne un procédé de fabrication de fibres d'oxyde de métal ou de fibres de métal présentant un diamètre de l'ordre de 0,1 à 999 nm par électrofilage d'une solution contenant un ou plusieurs polymères, un ou plusieurs sels métalliques, un ou plusieurs agents complexants ainsi qu'un solvant. Le procédé comprend les étapes suivantes : (a) préparation d'une solution contenant un ou plusieurs polymères, un ou plusieurs sels métalliques, un ou plusieurs agents complexants ainsi qu'un solvant, ladite solution présentant une teneur en eau d'au moins 50 % en poids, (b) électrofilage de la solution et (c) élimination du polymère.
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung von Metalloxidfasern bzw. Metallfasern mit einem Durchmesser im Bereich von 0,1 bis 999 nm durch Elektrospinnen einer Lösung enthaltend ein oder mehrere Polymer(e), ein oder mehrere Metallsalz(e), einen oder mehrere Komplexbildner sowie ein Lösungsmittel umfassend die Schritte: (a) Bereitstellen einer Lösung enthaltend ein oder mehrere Polymer(e), ein oder mehrere Metallsalz(e), einen oder mehrere Komplexbildner sowie ein Lösungsmittel, wobei die Lösung einen Wassergehalt von mindestens 50 Gew.-% aufweist, (b) Elektrospinnen der Lösung und (c) Entfernen des Polymers.
