Stärker als Stahl

Forscher spinnen ultrafeste Zellulosefäden an DESYs Röntgenlichtquelle PETRA III

(PresseBox) (Hamburg, )
Ein schwedisch-deutsches Forscherteam hat bei DESY erfolgreich ein neues Verfahren zur Produktion extrem starker Zellulosefäden getestet. Die innovative Methode flechtet ultrafestes Garn aus nanometerkleinen Zellulose-Fasern, indem diese alle parallel ausgerichtet werden. Die Wissenschaftler präsentieren die Prozedur im Fachjournal "Nature Communications".

Zellulose ist der Hauptbestandteil der pflanzlichen Zellwand und formt dort winzigen Fädchen, die sogenannten Fibrillen. "Gemessen am Gewicht sind unsere Fäden stärker als Stahl und Aluminium", erläutert Hauptautor Prof. Fredrik Lundell vom Wallenberg-Holzwissenschaftszentrum an der Königlichen Technischen Hochschule KTH in Stockholm. "Die echte Herausforderung ist allerdings, daraus Biomaterialien mit hoher Steifigkeit zu machen, die beispielsweise für Rotorblätter von Windkrafträdern eswzfxp mkgkgw tjinqtd.
