The helical structures possess unique physical and chemical properties,such as superelasticity,high specific strength,chirality,and electromagnetic cross-po-larization characteristics.With the development of nanoscience and nanotechnology,helical structures with various scales have been discovered or synthesized artifi-cially.Among them,the helical carbon materials receive much attention around the world.Herein,we present a brief review of the development of helical carbon materials in terms of structures,synthesis techniques and mechanisms,and applications.The controllable designing of catalysts,carbon sources and reaction parameters plays a key role to optimize the properties of the helical carbon materials.At the same time,the applications in microwave absorption devices,sensors,catalysts,energy conversions and storage devices,and solar cell are also presented.For the good chemical and physical properties,helical carbon materials have a good application prospect in many fields.The potential issues and future opportunities of the helical carbon materials are also proposed.
