The electrical, mechanical and physical properties of carbon nanotubes have been applied in different fields. The fabrication new composite materials of carbon nanotubes by various methods illustrates how new avenues are used in many areas of science and technology. The coating method of carbon nanotubes is one of the fabrication techniques. This review therefore, aims to present a general lid on different kinds of coating methods employed to fabricate new composite materials of carbon nanotubes. Their potential applications are also addressed. The key conditions of preferable coating methods that commensurate with CNT antennas applications are then proposed in this paper.
