Radial Breathing Mode Frequency of Multi-Walled Carbon Nanotube Via Multiple-Elastic Thin Shell Theory
نویسندگان
چکیده مقاله:
In this paper, the radial breathing mode (RBM) frequencies of multi-walled carbon nanotubes (MWCNTs) are obtained based on the multiple-elastic thin shell model. For this purpose, MWCNT is considered as a multiple concentric elastic thin cylindrical shells, which are coupled through van der Waals (vdW) forces between two adjacent tubes. Lennard-Jones potential is used to calculate the vdW forces between adjacent tubes. The RBM frequencies of MWCNTs predicted by the present shell model are in excellent agreement with the available experimental and atomistic results with relative errors less than 2.5%. The results emphasize the utility of multiple-elastic thin shell theory for modelling the RBM vibrational behaviour of MWCNTs.

متن کاملValidation of Shell Theory for Modeling the Radial Breathing Mode of a Single-Walled Carbon Nanotube (RESEARCH NOTE)
In this paper, the radial breathing mode (RBM) frequency of single-walled carbon nanotube (SWCNT) is studied based on the thin shell theory. For this purpose, SWCNT is considered as an elastic thin cylindrical shell. The dynamic equation of RBM is derived using the Hamilton’s principle. An analytical solution of the RBM frequency of SWCNT is obtained. The advantage of this formulation is that i...

In this paper, an elastic shell model is presented for postbuckling prediction of a long thinwalledcylindrical shell under axial compression. The Ritz method is applied to solve the governingequilibrium equation of a cylindrical shell model based on the von-Karman type nonlinear differentialequations. The postbuckling equilibrium path is obtained using the energy method for a long thin-walledcy...
متن کاملAnomaly in the radial breathing mode of resonant Raman scattering from vertically aligned single-walled carbon nanotube films
Polarization-dependent resonance Raman spectra of a single-walled carbon nanotube (SWNT) array were measured such that the polarization of the scattered light was selected either parallel or perpendicular to that of the incident light. For the parallel configuration, radial breathing mode (RBM) peaks exhibited two different polarization dependencies. One group (dominated by a peak at 203 cm-1) ...
متن کاملQuantum-coupled radial-breathing oscillations in double-walled carbon nanotubes.
Van der Waals-coupled materials, ranging from multilayers of graphene and MoS(2) to superlattices of nanoparticles, exhibit rich emerging behaviour owing to quantum coupling between individual nanoscale constituents. Double-walled carbon nanotubes provide a model system for studying such quantum coupling mediated by van der Waals interactions, because each constituent single-walled nanotube can...
متن کاملThe Effects of Functionalized Multi-walled Carbon Nanotube on Mechanical Properties of Multi-walled Carbon Nanotube/Epoxy Composites
The mechanical properties of the multi-walled carbon nanotube (MWCNT)/epoxy composites affected by carboxyl and amino functionalized MWCNT are investigated. Tensile tests of the specimens were carried out to obtain mechanical properties of MWCNT/epoxy composites for various weight-percents (wt %) of MWCNTs. In order to properly predict the mechanical properties of MWCNT reinforced epoxy composi...
