Embodiment 1

[0048] A horizontal chemical vapor deposition carbon nanotube growth furnace is adopted. The carrier gas flow rate of the chemical vapor deposition carbon nanotube growth furnace 1 is 2000ml / min. The film substrate is collected by filter paper, and the filter paper with a diameter of 50mm is placed in the film-forming collection fixture. 6, the edge of the filter paper is fixed by using the pressing sheet in the film-forming collection and fixing device 6, and after the film-forming and collecting and fixing device 6 is placed in a suitable position inside the pipeline of the film collecting chamber 8, the film-forming and collecting and fixing device 6 is clamped by the inside of the pipeline. slot fixed. First, open the ball valve switch 5, close the vacuum pump gas circuit switch 12 and the bypass gas circuit switch 15, and collect the single-walled carbon nanotube film; after the collection, close the ball valve switch 5, turn on the vacuum pump gas circuit switch 12 and th...

Embodiment 2

[0050] A vertical chemical vapor deposition carbon nanotube growth furnace is adopted. The carrier gas flow rate of the chemical vapor deposition carbon nanotube growth furnace 1 is 4000ml / min, and the film substrate is collected by a microporous filter membrane. The experimental steps of Example 1 were repeated, and the film samples whose growth time was 1 minute, 2 minutes, and 3 minutes were collected respectively, such as image 3 shown. Same as Example 1, the color of the film becomes darker with the increase of collection time, but all three films are very uniform.

Embodiment 3

[0052] A vertical chemical vapor deposition carbon nanotube growth furnace was adopted, the carrier gas flow rate of the chemical vapor deposition carbon nanotube growth furnace 1 was 1000ml / min, and the film substrate was collected with aluminum foil. Repeat the experimental procedure of embodiment 1, collected the thin film sample that growth time is 1 minute, as Figure 4 shown. The aluminum foil loaded with the carbon nanotube film is darker in color (right) compared to the aluminum foil without the carbon nanotube film (left).

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.
