Helical carbon fibers, one of the typical representatives of chiral materials, have attracted more and more attention for the controllable and adjustable advantages such as composition, structure, morphology, permittivity parameter, permeability parameter and chiral parameters. In this paper the preparation methods, controlling of structure and morphology, growth mechanism and property of micro-wave absorption of helical carbon fibers are reviewed. Controlling the structure and morphology is an effective method to adjust and improve the property of micro-wave absorption. The development trends and some problems related to helical carbon fibers are discussed briefly.
