6 1 Schematic Representation Of The Synthesis Of Carbon Nanotube Grown Download Scientific 6.1 schematic representation of the synthesis of carbon nanotube grown on si composite yarns. (a) first carbon nanotube films are drawn from cnt arrays. Cnt growth by cvd method in its simplest form. the process involves passing a hydrocarbon vapor (typically 15–60 min) through a tubular reactor in which a catalyst material is present at sufficiently high temperatur. (600–1200°c) to decompose the hydrocarbon. cnts grow on the catalyst in the reactor, which are collect.

Schematic Representation Of Carbon Nanotube Structures 4 Download Scientific Diagram This paper gives an overview of different approaches to synthesize cnts and then focuses on the floating catalyst method to form cnt sheets. a method is also described in this paper to modify the properties of macroscale carbon nanotube sheets produced by the floating catalyst method. Hematic diagram of this method is given in figure 1.6. soot containing the nanotubes is collected from the water cooled copper collector at the end of the apparatus, from the walls of the quartz tube. In this study, the green synthesis method of creating carbon nanotubes (cnts) was effectively applied. burnt coconut shells were used as the carbon source, while plant extract was used as the catalyst. Synthesis of carbon nanotubes by chemical vapor deposition over patterned catalyst arrays leads to nanotubes grown from specific sites on surfaces. the growth directions of the nanotubes can be controlled by van der waals self assembly forces and applied electric fields.

Preparation of capsules followed the established process o lbl deposition onto microparticles (figure 1). in the first step, carbon nanotubes are suspended in water and adsorbed onto polyelectrolyte multilayer (pem) capsules. Schematic representation of these synthesis processes is shown in figure 2. iijima (iijima, 1991) used the arc discharge method for production of cnts. the process involved condensation of carbon atoms generated from evaporation of a solid carbon source. The electrodes are momentarily brought into contact and an arc is struck. the synthesis is carried out at low pressure (30 130 torr or 500 torr) in controlled atmosphere composed of inert and or reactant gas. the distance between the electrodes is reduced until the flowing of a current (50–150 a).
