Mechanical properties of supracrystals(a)(a)Contribution to the Focus Issue Self-assemblies of Inorganic and Organic Nanomaterials edited by Marie-Paule Pileni.

Abstract

The mechanical properties of three-dimensional self-assembled nanocrystals, as so-called supracrystals, are correlated with: i) the type of terminate groups of coating agents used to stabilize the nanocrystals; ii) their interactions with the nanocrystal surface atoms; iii) the nanocrystal morphology; iv) the interparticle distance between nanocrystals; v) translational and orientational ordering of atomic lattice planes of nanocrystals. The Young moduli evolve from a few MPa to GPa by controlling the various factors mentioned above.
