Abstract

ABSTRACT As electronic devices evolve toward miniaturization, integration and diversification, developing composites with thermal management and broadband microwave absorption has become critical for addressing electromagnetic compatibility and heat-dissipation challenges. Inspired by the multilevel thorny structure of a cactus, this study proposes a biomimetic 3D network structure via a ‘direction-decoupling’ design to enhance thermal conductivity and microwave absorption. Boron nitride nanosheets (BNNS) form horizontal thermal pathways, while cobalt-catalysed nitrogen-doped carbon nanotube arrays (Co@NCNTs) are vertically grown in the interlayer for cactus-like heterostructure fillers. Finally, composites…
