A method for making a carbon nanotube composite includes: forming a self-supporting carbon nanotube film structure; providing a hardenable liquid material; immersing the carbon nanotube film structure in the hardenable liquid material; and solidifying the hardenable liquid material to achieve a carbon nanotube composite. The composition of the invention includes about 0. First, the transmitter and the receiver of the packet designate an isochronous channel for the communication. A plurality of cam devices is also formed in the sheet hole-punching device. 0550 kgkg or less environment, thereby effecting crystal transition.
