Unique Challenges in Graphane Recykling

Recykling graphene is fundamentally different from recykling bulk materials such as metals or plastics. The very contributies that make graphene valuable - it s single- atom squatness, high aspect ratio, and sensitivity to o structural defects - also make it difficult to recover with out degradation. Key consistenges include:
