Facile fabrication of Hildewintera-colademonis-like hexagonal boron nitride/carbon nanotube composite having light weight and enhanced microwave absorption.

Hildewintera-colademononis-like hexagonal boron nitride carbon nanotubes (BN@CNT) composites can be fabricated via two steps: a composite structure predesign in a solvent and a subsequent thermal treatment process at high temperature. The as-obtained hildewintera-colademononis-like BN@CNT composites contain porous h-BN microrods as stems and CNTs as spines. The densities and specific surface area of these BN@CNT composites can be tuned by adjusting the relative amounts of CNTs in the composites, which can reach 0.
