Fabrication of nanostructured clay-carbon nanotube hybrid nanofiller by chemical vapour deposition

► Carbon nanotubes with very high selectivity (ID/IG = 0.53) were grown over montmorillonite. ► Novel carbon nanotubes-montmorillonite (CNT/MM) hybrid materials were produced. ► CNT/MM hybrid material is a promising candidate for Nafion based nanocomposite membranes.
