AI Article Synopsis
- Graphene materials are valuable due to their extraordinary properties, but their production is challenging.
- This research explores a plasma-based technique that exfoliates and modifies graphite flakes using shock waves and chemical species at a liquid surface.
- The resulting process reduced the thickness of graphite by 20% and produced a unique structure with minimal defects, offering a promising new approach to creating functionalized graphenic materials.
Article Abstract
Graphene materials exhibit extraordinary properties, but are difficult to produce. The present work describes the possibility of using a plasma process to exfoliate and functionalize graphite flakes. An impulse plasma phase is generated at a liquid surface to produce chemical species and shock waves in order to modify the reactive liquid as well as the graphite flakes. With this process, industrial graphite was treated. 20% thickness diminution was observed, and the formation of a random turbostratic structure. The exfoliation occurs with small amount of functionalization of the surface. Even after treatment, the graphite flakes present a low defect density compared with other treated graphite obtained by more conventional chemical treatments. This process is a new way to exfoliate graphite and to produce functionalized graphenic materials.
