Synthesis of carbon nanotube arrays on quartz-based fibrous materials and their morphological characterization

Abstract

Abstract Carbon nanotubes (CNTs) were synthesized on quartz-based fibrous materials via chemical vapor deposition using camphor. Quartz wool with two different fiber diameters, and quartz filter paper were used as the substrate materials for the synthesis. Quartz wool produced a high yield of CNTs, and the arrays on the fibers had characteristic plate-shaped aligned structures. In addition, CNTs were grown on the quartz filter paper fibers; however, most of these CNTs were not aligned. The effects of the fiber diameter and interfiber distance of the substrate materials on the yield and morphology of the resulting CNTs are discussed.
