SYNTHESIS OF CARBON NANOTUBES USING PALM OIL BY THERMAL CVD METHOD

Abstract

Carbon nanotubes (CNTs) are a new class of materials that have wonderful novel and useful properties. The estimated increase in manufacture makes carbon nanotube more exposing to human being. CNT has a very wide application in electronics due to increasing resistivity of copper with scaling of transistor. Due to the rising demands of current density requirements are needed to identify new wiring solutions for nanometer scale VLSI technologies. Metallic carbon nanotubes have the property that can potentially used the challenges faced by copper and hence extend the lifetime of electrical interconnects. CNTs are also useful in many biomedical applications, and hence their biocompatibility, biodistribution needs to be carefully assessed. Different types of CNTs can be produced in different ways. Most common technique used are arc discharge, laser ablation, CVD and flame synthesis. CNT produced by this method have impurity hence we need to purify it. Purification techniques are oxidation, acid treatment, annealing, sonication, filtering and funcationalisation technique. Economically large scale production and purification techniques still have to be developed.
