AB - Carbon nanotubes (CNTs) have garnered significant attention as fillers in various composite materials due to their exceptional mechanical strength, high electrical conductivity, and thermal conductivity. However, their application is often restricted by their limited thermal stability at elevated temperatures during the fabrication of CNT-based composites. In this study, we developed an innovative technique to enhance the thermal stability of CNTs by coating their surfaces with nanometer-sized alumina (Al2O3) layers using powder atomic layer deposition (PALD). The thickness of the Al2O3 layer was precisely controlled by adjusting the precursor injection cycle in the PALD process. Thermogravimetric analysis (TGA) revealed a significant improvement in the thermal stability of the coated CNTs, with an increase of 70°C in the onset temperature of degradation. This study introduces a novel approach to improving the thermal stability of CNTs via PALD coating, which holds potential for broadening the scope of applications for carbon-based materials.
