Abstract
This work reports on our earnest effort to develop a pulsed laser ablation deposition system for the production of carbon nanotubes (CNTs). The correct condition such as the pressure, ablation time, power of laser will result in different struc tures and morphology of the tubes. A T-shaped stainless steel chamber was designed. Nd:YAG laser with 532 nm wavelength, 10.54W output power and pulsed width of 5-7 ns was used to ablate a pel let form graphite for 30 minutes. The morphology and the structural properties of the tubes were stu died. The results were compared with graphite pelle t filled with 10 weight % of Nickel as catalyst. It w as found that an Argon environment with the Ni catalyst result in the formation of a web-like carb on nanotubes. XRD profile and TEM image confirmed the formation of CNTs.
Highlights
The carbon nanotubes (CNTs) peak in the diffraction patterns deposited on the glass substrate is broad as a result of the nano-size particles
The effects of various processing conditions on the growth yield of carbon nanotubes (CNTs) was Carbon nanotubes emerged recently as unique extensively studied by many researchers[3,5,7,8]
This work reports our earnest effort to develop a plastics are in EMI/RFI shielding, which has uses, in pulsed laser deposition (PLD) system
Summary
The CNTs peak in the diffraction patterns deposited on the glass substrate is broad as a result of the nano-size particles. SEM image shows the formation of cauliflower-liked carbon, cones and ridges on the side of the diameter of the rotated target ablated by 10.54W laser power with 4 torr argon gas pressure.
