Microwave (MW) irradiation is often used in preparation of nanomaterials. Here, we investigate MW exfoliation patterns of intercalated fluorinated graphite (CF) depending on the nature of the "guest". The resulting highly exfoliated graphites (multi-layer graphenes) show advantageous characteristics, as compared to the products of convective heating.

The resulting materials were fully characterized using elemental analysis, infrared spectroscopy, Raman spectroscopy, thermogravimetric analysis, X-ray diffraction, scanning electron micrographs, and transmission electron microscopy. The findings reveal that benzimidazole rings were formed during the reaction, and the mass content of nitrogen in the obtained material varied from 12.

- The research describes a process for fluorinating few-layer graphene (FLG) using ClF3 at low temperatures to create a new derivative with a composition of C2F.
- Transmission electron microscopy (TEM) revealed that the product consists of transparent sheets with fewer than 10 layers, and spectroscopic analyses showed predominantly covalent C-F bonds without the "semi-ionic" bonds found in bulk fluorinated carbons.
- The study highlighted that FLG's structure prevents ClF3 intercalation, contrasting with bulk graphite, and established the need for over 12 layers for such intercalation, demonstrating significant differences in properties between FLG and graphite.
