Title:
CARBON NANOTUBE SHEET ROLL EMITTER WITH IMPROVED STRUCTURAL STABILITY, MANUFACTURING METHOD THEREFOR, AND FIELD EMISSION DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/092425
Kind Code:
A1
Abstract:
One embodiment of the present invention provides a carbon nanotube sheet roll emitter with improved structural stability, a manufacturing method therefor, and a field emission device using the same. The carbon nanotube sheet roll emitter comprises a carbon nanotube sheet roll in which a carbon nanotube sheet is wound around the central axis of the carbon nanotube sheet roll, wherein the carbon nanotube sheet is formed by combining a plurality of carbon nanotube bundles with one another through covalent bonding. According to an embodiment of the present invention, there is an effect in which an emitter which is structurally stable and can be stably used even at a high output may be provided.
