Carbon nanotube in different shapes

TLDR

Carbon nanotubes, whose crystalline hexagonal structure can be altered by defects to produce varied morphologies, have been extensively studied and are known to exhibit shape‑dependent properties with diverse applications. This review examines the growth‑induced morphologies of carbon nanotubes and their potential applications. The authors survey the growth processes that produce various CNT shapes, describing their morphologies and application prospects.

Abstract

Carbon nanotubes (CNTs) have been well studied theoretically and experimentally. Perfect CNTs have a crystalline structure formed by hexagonal network; defects cause the tubule to curve. CNTs with different tubule morphologies have their own special properties and potential applications. So far, many different shapes, such as straight, waved, coiled, and branched, are predicted, observed, and target synthesized. This article reviews CNTs in different shapes formed during growth, their morphologies and their possible applications.
