Vertically Aligned Pearl-like Carbon Nanotube Arrays for Fiber Spinning

摘要

Due to their unique structure and physical properties and numerous potential applications, carbon nanotubes have been extensively studied recently and are expected to attract more attention in the future. Morphology control of carbon nanotubes represents one of the most explored directions. Except for the normal linear structure, nanotubes with morphologies of ring, rocket, branch, cone, bulb, star, cup-stacked-type, bamboo, and helix have been widely investigated. Here we first report another new type of nanotubes with a pearl-like morphology. This unique morphology enables nanotubes with much improved fiber spinability.
