【 摘 要 】

tsThe delicate “3D helix–2D sheet–1D fiber–0D dot” hierarchical aerogels were successfully synthesized.The graphene sheets are uniformly intercalated by helical carbon nanocoils, which endow the as-obtained aerogel with abundant porous structures and better dielectric properties.By adjusting the growth parameters of 0D core-shell structured particles and 1D carbon nanofibers, the tunable electromagnetic properties and excellent impedance matching are achieved.
