Mechanical andLiquid- Phase Exfoliation

Exfoliation methods breaks graphite into graphane layers using mechanical force (np., sonication) or chemical intercalation. Liquid-faxe exfoliation produces graphane disepens that can be mixed with polimers, resins, or metals to create nano composites. While exfoliated grafoliate often has more defectes than CVD material, it is cheaper and more esily dispersed, making it appropriable for bulk composite produciton.
