A continuous collection method and special device for single-walled carbon nanotube film

Abstract

The invention relates to a controllable uniform collecting technology of a single-walled carbon nanotube film and particularly relates to a continuous collecting method of the single-walled carbon nanotube film growing by virtue of a floating catalyst method and a special device. A connect installation ball valve switch and a film collecting chamber are designed and connected to the tail end of a chemical vapor deposition carbon nanotube growth furnace. On the premise that any growing conditions are not changed, high quality single-walled carbon nanotube films are directly and continuously collected on the surfaces of various film substrates. The single-walled carbon nanotube films growing by virtue of the chemical vapor deposition method by using the floating catalyst under conditions of normal temperature and pressure are collected to the surfaces of various substrates. The single-walled carbon nanotube films which are in inch grade, controllable in density and uniform are continuously collected by regulating the deposition time and growing parameters. Therefore, the technical problems that the existing carbon nanotube film collecting process is poor in uniformity, small in draw ratio, limited in size and the like are solved.
