Kühle Satelliten und biegsame Elektronik

Dünne Zwischenschichten stärken mehrschichtige Werkstoffe

(PresseBox) (Dübendorf, )
Superleicht, superflexibel, superisolierend: Um Satelliten vor Temperaturextremen zu schützen, kommt eine mit Aluminium beschichtete Polymerfolie zum Einsatz. Forschende der Empa Thun machen das Material durch den Einsatz einer hauchdünnen Zwischenschicht noch widerstandsfähiger. Auch flexible Elektronik und medizinische Sensoren könnten so verbessert werden.

Wer kennt es nicht, das archetypische Bild eines Satelliten: Zwei ausgestreckte Solar-«Flügel» und ein kompakter Körper, eingepackt in goldig oder silbrig schimmernde Folie. Genau mit dieser Folie beschäftigen sich Forschende aus dem Labor «Mechanics of Materials and Nanostructures» an der Empa in Thun. Ihre weite Verbreitung verrät es bereits: Die Folie ist für Satelliten und Raumsonden enorm wichtig.
