SYNTHESIS OF CARBON NANOTUBES AND THEIR USE IN PHENOLIC COMPOSITES

Abstract

Carbon nanotube is a fascinating material having outstanding properties have inspired the researchers to adopt their properties for application point of view. In this study firstly carbon nanotubes have been synthesized by dc arc discharge technique. The parameters such as pressure inside the chamber, amount of the catalysts and the amount of the catalyst Fe were tried to optimize to get higher yield. Carbon nanotubes were obtained by the same technique on chamber deposits. Carbon nanotubes synthesized by above technique have been characterized by scanning electron microscopy, X-ray diffraction, and TGA. The outstanding mechanical properties of carbon nanotubes have also attracted researcher to adopt CNTs as reinforcement for composites. In this study carbon nanotubes were reinforced with phenolic resin in 0 and 2% volume fraction. The Composite samples prepared in this study were of dog bone shape with volume of 1 cc3 approximate. The mechanical properties, tensile strengt...
