Liquid Phase Exfoliation

Liquid phase exfoliation is a process used to produce thin layers of materials, such as graphene, from bulk substances like graphite. It involves dispersing the bulk material into a suitable liquid and then applying energy—often through sonication or agitation—to separate the layers. The liquid helps stabilize and keep these layers apart, preventing them from re-stacking. This method allows for large-scale production of nanosheets in a controlled manner, making advanced materials more accessible for various applications like electronics, composites, and sensors.
