- Abstract
Boron-doped helical carbon nanotubes (B-HCNTs) were obtained by annealing HCNTs under the boric oxide presence. The morphology and structure of HCNTs remained unchanged even after annealing and B-doping. HCNTs displayed excellent electromagnetic wave (EMW) absorption, judging by the corresponding optimal reflection loss and the absorption bandwidth values equal to − 47.86 dB and 3.20 GHz, respectively. Quick and straightforward synthesis process, excellent chemical stability and low density make our B-HCNTs promising as lightweight and efficient microwave absorbers.
