Embodiment 1

[0024] Weigh 0.15g MWCNTs into a three-necked flask, then add 30g (45wt%) concentrated nitric acid, ultrasonically disperse for 30min, then raise the temperature to 100°C, and acidify for 30h. After the reaction, the carbon tube suspension was filtered, washed and dried to obtain MWCNTs after acidification treatment. Then weigh 0.1435g SnCl 4 ·5H 2 O, 1.1732g InCl 3 4H 2 O, put it into a three-necked flask, add 80mL of deionized water and the above-mentioned acidified MWCNTs, stir well, heat up to 60°C, then add ammonia water dropwise to the three-necked flask to pH=8.5, and mechanically stir at 150 rpm for a total of Precipitation reaction 4h. After the reaction, the product is suction filtered, washed and dried to obtain carbon nanotubes assembled with indium tin hydroxide. The above precursor products were put into a crucible and placed in a muffle furnace, and the temperature was raised from room temperature to 330 °C at a heating rate of 3 °C / min, kept for 2 h, and t...

Abstract

The invention relates to a preparation method of nano indium-tin oxide / mutiple-wall carbon nano-tubes composites, which comprises the steps that strong oxidative acids are added into a three-necked flask containing mutiple-wall carbon nano-tubes; ultra audible sound is dispersed for 20-40min, the temperature rises to 100-120 DEG C, and the strong oxidative acids are processed by acidification for18-48h; when the temperature is 5-35 DEG C, the acidified mutiple-wall carbon nano-tubes are dispersed into a mixed solution of indium salt and tin salt, the ultra audible sound is dispersed for 20-40min and the temperature rises to 50-70 DEG C, and the mixed solution is adjusted by an alkali solution until the pH value equals to 8.5-9.5; the mixed solution is stirred by a machine, and then the mutiple-wall carbon nano-tubes coated by the nano indium-tin oxide are obtained after situ coprecipitation reaction for 4-8h; the mutiple-wall carbon nano-tubes coated by the nano indium-tin oxide are arranged in a muffle furnace to be calcined at the temperature of 300-350 DEG C, and the nano indium-tin oxide / mutiple-wall carbon nano-tubes composites are prepared at last. The preparation method issimple and has moderate reaction condition, and is easy for industrialization.

Description

technical field [0001] The invention belongs to the field of preparation of composite materials, in particular to a preparation method of nanometer indium tin oxide / multi-wall carbon nanotube composite material. Background technique [0002] Metal oxide nanoparticles have broad application prospects in high-tech fields due to their physical effects such as surface effects, small size effects, quantum size effects, and macroscopic quantum tunneling effects, as well as their unique optical, electrical, and mechanical properties. [0003] Because of their unique structure, electricity, mechanics, and hydrogen storage properties, carbon nanotubes have broad application prospects in many new fields such as nanoelectronic devices, super composite materials, hydrogen storage materials, and catalyst carriers. Carbon nanotubes are one-dimensional nanomaterials with hollow structures and high aspect ratios. Therefore, the assembly of one-dimensional nanoscale metal oxide / carbon nanotu...
