Characterization of Single-Walled Carbon Nanotubes
ثبت نشده
چکیده
Carbon nanotubes (CNTs) belong to the family of synthetic carbon allotropes and are characterized by a network of sp2 hybridized carbon atoms. The one dimensional (1D) carbon nanotubes can thus be queued between their zero dimensional relatives fullerenes and the two dimensional (2D) relative graphene. The structure of nanotubes has first been described as helical microtubules of graphitic carbon in 1991 by Iijima, who generated the novel material by an arc discharge evaporation process originally designed for the production of fullerenes.1 CNTs are theoretically constructed by rolling up a graphene sheet into a cylinder with the hexagonal rings joining seamlessly.

Synthesis 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 کاملA PARAMETRIC STUDY ON THE GROWTH OF SINGLE-WALLED CARBON NANOTUBES OVER CO-MO/MGO NANOCATALYST IN A FLUIDIZED BED REACTOR BY CCVD METHOD
Single-walled carbon nanotubes (SWNTs) with high yield and quality were synthesized using chemical vapor deposition (CVD) over Co-Mo/ MgO nanocatalyst in a fluidized bed reactor. Different parameters such as temperature, the ratio of hydrocarbon source to hydrogen, the flow rate of gas, growth time, the size of catalyst particles, heating rate, and the kind of hydrocarbon source were examined t...
متن کاملLinkage of doxycycline onto functionalized multi-walled carbon nanotube and morphological characterization
In this paper functionalized multiwall carbon nanotubes (FMWCNT) were modified using doxycycline, containing reactable nitrogen, which can attach chemically to functionalized MWCNT. The synthesized nano compounds were characterized by Fourier transform infrared spectroscopy (FT-IR) and Raman spectroscopy. These spectrums proved the existence of nitrogen atoms of amide functional groups. The mor...
متن کاملRadius Dependence of Hydrogen Storage Inside Single Walled Carbon Nanotubes in an Array
In this study, we have investigated radius dependence of hydrogen storage within armchair (n,n) single walled carbon nanotubes (SWCNT) in a square arrays. To this aim, we have employed equilibrium molecular dynamics (MD) simulation. Our simulations results reveal that radius of carbon nanotubes are an important and influent factor in hydrogen distribution inside carbon nanotubes and consequentl...
