Carbon nanotube initiated formation of carbon nanoscrolls
نویسندگان
چکیده
The unique topology and exceptional properties of carbon nanoscrolls CNSs have inspired unconventional nanodevice concepts, yet the fabrication of CNSs remains rather challenging. Using molecular dynamics simulations, we demonstrate the spontaneous formation of a CNS from graphene on a substrate, initiated by a carbon nanotube CNT . The rolling of graphene into a CNS is modulated by the CNT size, the carbon–carbon interlayer adhesion, and the graphene–substrate interaction. A phase diagram emerging from the simulations can offer quantitative guideline toward a feasible and robust physical approach to fabricating CNSs. © 2010 American Institute of Physics. doi:10.1063/1.3479050

Ultrafast nano-oscillators based on interlayer-bridged carbon nanoscrolls
We demonstrate a viable approach to fabricating ultrafast axial nano-oscillators based on carbon nanoscrolls (CNSs) using molecular dynamics simulations. Initiated by a single-walled carbon nanotube (CNT), a monolayer graphene can continuously scroll into a CNS with the CNT housed inside. The CNT inside the CNS can oscillate along axial direction at a natural frequency of tens of gigahertz. We ...
متن کاملA simple mechanical technique to obtain carbon nanoscrolls from graphite nanoplatelets
A simple approach for the bulk production of carbon nanoscrolls (CNSs) is described. This method is based on the application of shear-friction forces to convert graphite nanoplatelets into carbon nanoscrolls using a bi-axially oriented polypropylene (BOPP) surface. The combined action of shear and friction forces causes the exfoliation of graphite nanoplatelets and the simultaneous roll-up of g...
متن کاملSynthesis and characterization of functionalized single - walled carbon nanotube/ chitosan/polyaniline nanocomposite
In this work the synthesis of polyaniline/chitosan/functionalized single- walled carbon nanotube nanocomposite is carried out. For this purpose single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. In other step, aniline monomers and chitosan were polymerized in the presence of Iron (III) chloride to sy...

متن کاملInsights into carbon nanotube nucleation: Cap formation governed by catalyst interfacial step flow
In order to accommodate an increasing demand for carbon nanotubes (CNTs) with desirable characteristics one has to understand the origin of helicity of their structures. Here, through in situ microscopy we demonstrate that the nucleation of a carbon nanotube is initiated by the formation of the carbon cap. Nucleation begins with the formation of a graphene embryo that is bound between opposite ...
