Research interests

Supramolecular Chemistry

Current research

We use the reversibility of macromolecular chemistry interactions to develop new materials:

  • Formation of Janus nanocylinders and nanoparticles
  • Supramolecular polymers for self-healing
  • Supramolecular polymers for adhesion
  • Additives for bitumen reinforcement

Recent results

We have developed a method for synthesizing molecules carrying directional and complementary associative groups in order to form Janus nanocylinders (Figure 1). With this general method of synthesis and by using different types of monomers it is possible to obtain Janus nanocylinders with modular properties.

Nature Commun. 2020, 11, 4760

The presence of associative stickers within low Tg polymers makes it possible to introduce nano-structuration and to modulate the dynamics of the chains. Thus, by introducing an additive into an industrial thermoplastic elastomer matrix, it is possible to provide self-healing properties
