摘要:
This disclosure includes a process that unexpectedly can produce very inexpensive graphene, functionalized graphenes, and a new compound called graphenol in particulate or dispersions in solvents. The process can also produce graphene layers on metallic and nonmetallic substrates. Further, the graphenol, functionalized graphenes, and graphene can be utilized to form nanocomposites that yield property improvements exceeding anything reported previously.
