GRaphene-based nAnocomposites via DynamIc covalENT chemistry for energy storage (GRADIENT)


Complexity in molecular assemblies emerges from the integration, via self-organisation, of different molecular components displaying specific functionalities at the macroscopic level not necessarily present at the level of the individual components. These complex systems offer a wealth of solutions and opportunities towards the generation of new materials with unique electrical properties.

In the field of energy storage, graphene is particularly appealing owing to its excellent electrical, mechanical, and thermal properties. Complex hybrid nanostructures obtained upon covalent assembly of functional molecular building blocks on graphene sheets hold great promise for such applications. Therefore, it is essential to understand and achieve full control over the architecture vs. function relationship in such complex systems.

GRADIENT targets at using for the first time dynamic covalent chemistry approaches on graphene to generate, under thermodynamic control, 2D and 3D functional nanocomposites based on chemically modified graphene as active components for electronics and energy storage applications such as supercapacitors and lithium storage.

By using the large portfolio of state-of-the-art techniques available in our laboratories for self-assembly at surfaces and interfaces as well as multiscale (in time and space) characterization, we will unravel the complex relationship between molecular nanostructure and electronic properties of graphene nanocomposites ultimately influencing the device performance. The work in GRADIENT will focus on:

  • The controlled engineering of 2D/3D graphene-based nanocomposites by use of dynamic covalent chemistry;
  • The study of the compositional, structural and electronic properties of 2D/3D graphene-based nanocomposites;
  • The fabrication of field-effect transistors, supercapacitors and Li-ion batteries based on 2D/3D graphene nanocomposites.
