Résumé (anglais)

The transfer of extraordinary properties of sp2-nanocarbons (NCs) from nano- to macro-scale is challenging due to the non-trivial control over their morphology and surface physicochemistry (1). The fundamental properties of NCs as a function of dimensionality from 0D to 3D remain incompletely understood, often with contradictory reports about their affinities and reactivities, hindering potential applications (2). At the same time, physicochemical modifications of 0D quantum dots (CQDs), 1D carbon nanotubes (CNTs), and 2D graphene/graphenoids enabling their individualization, frequently requiring development of functional 3D networks based on non-compromised morphology, are essential for their enhanced interfacial, electrical, thermal, mechanical, catalytic, and biological characteristics (Figure).

The proposed transformations, encompassing tunable covalent and non-covalent functionalizations, yielded NCs of superior properties. Specifically, concerning the ‘properties-by-design’ approach, we have designed and synthesized and/or manufactured: textronics for Holter electrocardiography (3), conductive (4) and superhydrophobic (5) coatings, high-performance heat transfer fluids (6), phase change materials (7), magnetic drug delivery systems (8), superlubricants (9), only-carbon 1D and 2D emulsifiers (10), and hybrid catalytic systems (11).
