“…Carbon nanocoils (CNCs) and micro-coiled carbon fibers have attracted significant attention in the field of carbon nanomaterials due to their unique helical morphologies and outstanding mechanical and electronic properties, and found applications as ultraviolet-ray absorbers, micro-antennas, micro/nano-tactile sensors, electromagnetic absorbers, nano-sized springs, magnetic beam generators, field emitters for flat panel displays, and electrochemical double-layer capacitors (EDLCs) [1][2][3][4][5]. EDLCs are energy devices with a high power density resulting from fast charge propagation between the negatively or positively charged plates and the ions in the electrolytic solution.…”

Abstract:Various types of coiled carbon filaments have been synthesized using chemical vapor deposition and other methods. These carbon filaments exhibit unique electrical and mechanical properties due to their versatile shapes and structures. To form coiled shapes, different types of catalyst compositions and reactive gases have been explored. Generally, coiled carbon filaments are classified by coil diameter and shape (e.g., microcoil and nanocoil). In this review, coiled carbon filaments are classified into three growth mechanism categories: (1) bidirectional double helical growth; (2) bidirectional twisted growth; and (3) tip single helical or twisted growth. Next, their synthesis methods and hypothetical growth mechanisms are discussed. Then, their electrical and mechanical properties are listed. Finally, potential applications and uses of coiled carbon filament are mentioned.

“…51 It was also observed that the use of metal promoters such as copper, chromium and tin, as well as alkali metals, aided the synthesis of the helices. 56,57 How these impact on the preparation conditions, growth mechanisms, structure and properties of helical carbon materials are still under intense investigation.…”

Materials made of carbon that can be synthesised and characterised at the nano level have become a mainstay in the nanotechnology arena. These carbon materials can have a remarkable range of morphologies. They can have structures that are either hollow or filled and can take many shapes, as evidenced by the well-documented families of fullerenes and carbon nanotubes. However, these are but two of the shapes that carbon can form at the nano level. In this review we outline the types of shaped carbons that can be produced by simple synthetic procedures, focusing on spheres, tubes or fibres, and helices. Their mechanisms of formation and uses are also described.
