| CN's | |
| There are many carbon nanostructures (CN’s) and most likely graphene and diamond are still the most interesting due to its physical properties. Synthesis of CN’s is made via diverse methods including vapor deposition, exfoliation (graphene) or the use of high pressure and temperature (diamond). Thus it is interesting to investigate a purely mechanical, simple and room temperature procedure to synthesize CN’s. This investigation deals with the products of mechanically milling carbon soot at room temperature that has rendered a different C allotrope herein identified as morphed graphene. Identification of a new allotrope is quite complicated due to the wide variety of known carbon phases and the pronounce effects of even subtle morphology changes as in the twisted layer graphene. Nevertheless different forms of evidence have been shown that lead to conclude that the product of the synthesis procedure in use (mechanical milling) indeed delivers a new allotrope [1]. Starting with carbon soot, milling develops a variety of phases ranging from graphene (single, double-layered) to diamond. Similar phases have been previously proposed from theoretical considerations and numerical calculations [2]. In this work, medium dose electron microscopy is used to an in-depth characterization of the product phases and especially this newly found allotrope known as Rh6 and Rh6-II having a pure sp2 bonding. | |
