Molten aluminum has very low tendency to wet carbon nanotubes (CNTs) due to the large difference of surface tension forces, which is the major issue in the liquid phase processing of Al-CNTs composite. Here in this study, a simple approach is presented to coat aluminum on CNTs using potassium hexafluorotitanate. During the process, titanium carbides were formed on the surface of the nanotubes providing wetting sites to coat aluminum in the liquid phase. These coated nanotubes could be used as a precursor, for not only liquid phase process but also for solid phase processing, to fabricate Al-CNTs composites.
