Method for electrophoretic anode deposition preparation of carbon nanotube field-emission film

Abstract

The invention discloses a preparing method of launching film of carbon nanometer pipe field in the nanometer material preparing technical domain, which comprises the following steps: dispersing original carbon nanometer pipe in the sodium dodecyl sulfate solution through ultrasound; forming carbon nanometer suspension electrophoretic liquid; sedimenting dispersed carbon nanometer pipe on the surface of stainless steel or titanium anode; heating carbon nanometer pipe film slowly in the high-temperature furnace to 400 Deg C; insulating for 30 min; fetching; cooling protected by nitrogen.

Description

Technical field

[0001] The invention belongs to the application research field of nano materials. In particular, it relates to an electrophoretic anode deposition preparation method of a carbon nanotube field emission film widely used in micro-nano manufacturing. Background technique

[0002] In 1991, Iijima of Japan first discovered multi-walled carbon nanotubes (MWNT) with a diameter of 4-30nm and a length of 1um. Single-walled carbon nanotubes (SWNT) were also discovered in 1993, with diameters ranging from 0.4nm to 3-4nm and lengths up to several microns. Carbon nanotubes have unique electronic, mechanical and chemical properties, and have a wide range of applications in the fields of machinery, electrochemistry, energy, and display devices. Carbon nanotubes have two unique and excellent electrical properties, one is the field emission property, and the other is the double electrical property of carbon nanotubes. These two unique electrical properties make this new material h...
