Abstract

H2O2auf Druck hin: Die makroskopisch reversible Verformung von Polymeren in Kontakt mit Wasser ergibt genug H2O2 für chemische Synthesen im kleinen Maßstab. Die Menge an mechanisch synthetisiertem H2O2 nimmt bei Vergrößerung der Polymer-Wasser-Grenzfläche zu; in weichen, porösen Polymer-„Schwämmen“ ist ein Wirkungsgrad von 30 % für die Umwandlung von mechanischer in chemische Energie erreichbar.
