Abstract Nitrogen-doped carbon and helix carbon are both promising materials for capacitor and electromagnetic absorber. However, a combination of these two characteristics is rarely reported yet. Herein, nitrogen-doped helix carbon rods were prepared via a simple carbonization of self-assembled helix polyaniline rods. The morphology and structure of the polyaniline rods and carbon rods were analyzed. The results displayed that the synthesized carbon rods possessed well-defined helix structure, and the atomic ratio of nitrogen element was up to 7.09%.
