One-dimensional nanocomposite coatings are a new generation of coatings, which have promising applications in versatile fields. In this study, the novel carbon nanotubes (CNTs) reinforced nanocomposite coatings were explored through two-step strategy using both physical vapour deposition (PVD) approach and chemical vapour deposition (CVD) approach. Vertically aligned CNT films were deposited by plasma enhanced CVD at 450 , while density of the VACNT films was modified by using Ag impregnated composite catalyst films. Subsequently, Pt-CNT, Ag-CNT and DLC-CNT nanocomposite coatings were explored to find a feasible way to achieve the well-designed composite structure. Morphologies and microstructures of these nanostructures were characterized by scanning electron microscopy, atomic force microscopy, transmission electron microscopy and Raman spectroscopy, while fourprobe tester was applied to evaluate the electrical conductivity of the nanocomposite coatings. The results indicated that well-composited DLC-CNT nanocomposite coating can be achieved which exhibited better electrical conductivity compare to that of the pristine DLC coating.
