Abstract

Controlled incorporation of carbon nanotubes (CNT) with alumina (Al₂O₃) and zirconia (ZrO₂) nanoparticles using an electrostatic nano-assembly method for the fabrication of homogeneous CNT-incorporated Al₂O₃-ZrO₂ and CNT-incorporated shell-layer Al₂O₃-ZrO₂ composite granules is demonstrated. The spark-plasma-sintered CNT-incorporated shell-layer Al₂O₃-ZrO₂ artifact exhibited approximately 15 times higher electrical conductivity than a homogeneous CNT-incorporating artifact. This novel composite granule fabrication method using an electrostatic integrated assembly of colloidal nanomaterials would be beneficial for the development of multiscale and multicomponent composite materials.
