Ge, Lei and Chen, Jiuling and Chen, Jun and Zhu, Zhonghua and Rudolph, Victor (2012) Study on the controllable scale-up growth of vertically-aligned carbon nanotube arrays. Journal of Nanoscience and Nanotechnology, 12 (3). pp. 2722-2732. ISSN 1533-4880

Abstract

Vertically aligned carbon nanotubes (VA-CNTs) with high purity have been grown on quartz substrate via the gas phase catalytic chemical vapour deposition (CVD) by using ferrocene as the catalyst source and camphor as the carbon source. The effects of catalyst concentration, flow rate and water assistance on the morphology and structure of VA-CNTs are investigated by SEM, TEM, Raman and XPS characterizations. Under the optimized CVD conditions with modest ferrocene concentration and flow rate, dense and well VA-CNT arrays have been obtained. The water concentration should be controlled to improve CNTs alignment and impurity without damaging the walls of CNTs.
