Abstract

Nanoflakes, one type of supramolecules that consist of alternating inorganic layers separated by organic moieties, are demonstrated as a good candidate for energy absorption as a thin film. When a bulky molecule is inserted between those layered structures, both modulus and specific energy absorption were increased 12- and 9-fold, to 12.5 GPa and 275 J/g. Extensive interlayer glide during mechanical loadings could have rendered such a strong plastic deformation, suggesting promise in protecting engineered structures or human bodies against external impact with minimal added weight or volume. © 2010 WILEY-VCH Verlag GmbH & Co.
