potential applications in the field of coating materials for metal implants under high load-bearing
conditions. In addition, titanium substrates with such a coating can increase the surface roughness
at the nanoscale level and enhance osteoblast response. Such surfaces can be of immense use in
dental implants and orthodontic mini-implants (TADs).
18.4 Fabrication of carbon nanomaterials
The fabrication of CNTs has been extensively discussed in the previous chapter. Conventionally,
CNTs are fabricated by several methods, such as electric arc vaporization, laser vaporization,
gas phase catalytic growth from carbon monoxide, and chemical vapor deposition (CVD) from
