Abstract:
Carbon nanotube (CNT) bundles into ropes/ribbons were synthesized by expensive methods, arc discharge and chemical vapour deposition (CVD) using transition metal catalysts e.g., Co, Ni, Fe and Mo [1,2]. We produced CNT ribbons by pyrolysis of a sustainable waste material. Different geometrical structures, e.g.; knotted and twisted, U- and spiral-shaped CNT ribbons were observed in the images of scanning and transmission electron microscopy. The widths of the CNT ribbons measured varied in the ranges 18 ~ 80 nm. X-ray photoelectron spectroscopy analysis showed five types of carbon binding peaks, C–C/C–H (~77%), C–O–H (~9%), –C–O–C (~5%), C=O (~5%) and –O–C=O (~3%). The ratio of intensities of G and D bands, IG/ID was 1.61 analysed by Raman Spectroscopy. CNT ribbons grown on the surface of catalyst have potential for the fabrication of high-strength composite materials with polymer and metal.
