Theoretical Study of Addition Reaction of Carbene and Zigzag Single-walled Carbon Nanotube
The reaction mechanism between (H2C) and (7, 0), zigzag single-walled carbon nanotubes(ZSWCNTs) on two different orientation of C-C have been studied by semi empirical AM!method. The activation barriers of (H2C) adding to (7, 0) ZSWCNT are computed and compared.The effects of diameters of zigzag SWCNT on their binding energies were studied
متن کاملEffect of Nanotube Functionalization on the Properties of Single-Walled Carbon Nanotube/Polyurethane Composites
A commercially available aliphatic thermoplastic polyurethane formulated with a methylene bis(cyclohexyl) diisocyanate hard segment and a poly(tetramethylene oxide) soft segment and chain-extended with 1,4-butanediol was dissolved in dimethylformamide and mixed with dispersed single-walled carbon nanotubes. The properties of composites made with unfunctionalized nanotubes were compared with the...
متن کاملPressure-induced transition in magnetoresistance of single-walled carbon nanotubes.
We applied hydrostatic pressure (up to 10 GPa) to single-walled carbon nanotube bundles at low temperature (down to 2 K) to measure their magnetoresistance (MR) in a field up to 12 T. We found a pressure-induced transition in MR from positive to negative in the high-field regime. The onset of the transition occurs at approximately 1.5 GPa, which correlates closely with the tube shape transition...
متن کاملFunctionalization of the Single-walled Carbon Nanotubes by Sulfur Dioxide and Electric Field Effect, a Theoretical Study on the Mechanism
In this study, kinetics and mechanism of the sulfur dioxide adsorption on the single-walled carbon nanotubes (CNT) are investigated. Three single-walled carbon nanotubes, including the armchair (6,6), chiral (6,5) and zigzag (6,0) CNTs were chosen as the models and the different orientations of SO2 molecule relative to the CNT axis were considered. The B3LYP functional within the 6-3...
متن کاملبررسی اثر کرنش محوری بر روی ترابرد جریان در نانولوله کربنی دسته صندلی محدود (6 ،6)
In this paper, the uniaxial strain effect on the electronic properties of (6,6) finite armchair carbon nanotube was investigated by using the Green function technique and Landure-Buttiker formula. It was found that, in (6,6) finite carbon nanotube with 3q and 3q+1 length, where q is a certain integer, the current was induced by the application of a suitable tensile strain and compressive stra...
