Abstract Scope Supercrystalline nanocomposites are a new category of particulate-based materials. They consist of inorganic nanoparticles functionalized with organic ligands and organized into periodic structures. Such nanoarchitectures are fostered for a wide range of applications, spanning through optoelectronics, plasmonics, batteries and solar cells. However, supercrystalline nanocomposites are typically produced in 2D or 3D micro-sized domains. This work presents a new processing routine, capable of yielding bulk macroscale supercrystalline materials. Such a routine is adaptable to a multiplicity of materials systems, and, together with upscaling, leads to a greatly enhanced combination of mechanical properties (modulus, hardness, strength and fracture toughness are increased 1-2 orders of magnitude). The mechanisms underlying such properties boost are identified and correlated to structure and processing parameters. Additionally, by applying this processing routine to an iron oxide-based system, the option of tuning the magnetic behavior of the nanocomposites is integrated, up to the development of a bulk superparamagnetic material.
