2D materials for flexible electronics: synthesis and electrochemical characterization

The discovery of mechanical exfoliation, first demonstrated in 2004 for graphene, paved the way to create other materials with only two dimensions. Since then, more techniques such as chemical exfoliation were developed and existing ones improved to tailor 2D materials with different shapes, sizes, and compositions to match for example the requirements of flexible electronics.

In our group, we work on developing novel approaches for synthesizing nanoparticles with a thickness of only a few atomic layers. Particularly, we focus on the synthesis of transition metal sulfides and their exfoliation while employing only green, sustainable, and scalable protocols. Moreover, we aim at producing nanoparticles with a controlled thickness and a preferably high aspect-ratio while ending up with a stable and agglomeration-free suspension of particles. The characterization of the particles is then conducted using X-ray scattering methods, Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM).
