We demonstrate the synthesis of two composites consisting of carbon nanotubes and clay mineral montmorillonite. Synthetic and natural montmorillonites were examined as a matrix for synthesis of carbon nanotubes by hot filament chemical vapour deposition. Synthesis of carbon nanotubes on natural forms of montmorillonite but also on its synthetic form can only be achieved by incorporation of a catalytic phase. We have observed that there is no significant difference between natural and synthetic forms of montmorillonite as for the final carbon phase. In both cases the surface of the mineral is covered by a dense network of carbon nanotubes.Keywords: Carbon nanotubes, montmorillonite, chemical vapour deposition
