| Abstract Scope |
Supercrystalline nanocomposites have emerged within the broader fields of hybrid and nanoarchitected materials. They consist of inorganic nanoparticles, functionalized with organic ligands and arranged into periodic structures, reminiscent of atomic crystals. The combination of nano-building blocks and their periodic arrangement leads to emergent functional properties, with applications in optoelectronics, magnetic devices, catalysis, and more. A remarkable example is the fabrication of bulk superparamagnetic materials. A major obstacle towards their exploitation into devices is the lack of information on their mechanical behavior, accompanied by poor mechanical properties. An important step forward has been made by crosslinking the organic phase that interfaces the nanoparticles. This covalent network alters the deformation behavior of the nanocomposites, as multiscale ex- and in-situ studies show. Many analogies with atomic crystals emerge, even if length-scale and interactions between building blocks vary significantly. Future directions towards supercrystals with tunable behavior are outlined. |
