ABSTRACT
Carbon nanotubes (CNTs) were discovered by a Japanese physicist, Sumio Iijima, in 1991. The hydrogen is not involved in passing through the outlet of the reactor while the carbon is readily dissolved into the metal catalyst. The synthesis of CNTs done by the chemical vapor deposition process involves the thermal decomposition of hydrocarbon vapor at high temperature in a quartz tube producing carbon and hydrogen species. Bacterial cell adhesion onto a metal substrate is highly sensitive to the surface nature such as wettability and surface energy. Micro/nanoscale surface roughness is one of the facile techniques that have been used to fabricate such superhydrophobic surfaces unveiling an outstanding water repellency attribute. The C–F bond that presents in Polytetrafluoroethylene (PTFE) has exceptionally high bonding energy, typically >100 kg/mol, resulting in a very low surface free energy of PTFE. The chapter describes the fabrications and applications demonstrating the uses of superhydrophobic CNT–PTFE composites
