Continuous preparation and transfer method for meter-scale single-walled carbon nanotube film and special device

Abstract

The invention relates to a continuous preparation and transfer technology of a single-walled carbon nanotube film, in particular to a reel-to-reel continuous preparation and transfer method of a meter-scale single-walled carbon nanotube film and a special device. The method comprises the following steps: synthesizing a single-walled carbon nanotube by adopting a floating catalyst chemical vapor deposition method, and uniformly and continuously depositing a single-walled carbon nanotube film on the surface of a microporous filter membrane capable of continuously running by adopting a vapor suction filtration method; employing a roll-to-roll imprinting mode, wherein the carbon nanotube film can be transferred to the flexible plastic substrate from the surface of the microporous filter membrane, so the large-area uniform single-walled carbon nanotube film with the width reaching the meter level and the unlimited length is obtained. According to the roll-to-roll continuous preparation andtransfer technology of the single-walled carbon nanotube film, large-area and uniform macro preparation of the single-walled carbon nanotube film is achieved under the conditions of normal pressure and room temperature, and the roll-to-roll continuous preparation and transfer technology has important significance in promoting large-scale preparation and application of the single-walled carbon nanotube film in the field of transparent and flexible photoelectric devices in the future.
