Problems solved by technology

The first type is to use physical filling and coating methods to physically compound carbon nanotubes with metals or inorganic semiconductors. Although the mechanical and photoelectric properties of carbon nanotube materials have been improved, this method has complex processes and mechanical Disadvantages such as poor performance
The other is to obtain carbon nanotube / polymer composites by chemical modification or in situ polymerization. Although the process is simple, the dispersion uniformity and processability of carbon nanotubes in solvents are improved, and the size of the composite is relatively small. However, this method also has problems such as difficulty in controlling the degree of compounding and poor thermal stability of the composite material.

Embodiment 1

[0027] Add 1 g of multi-walled carbon nanotubes into a mixed strong acid solution consisting of 100 ml of concentrated sulfuric acid and concentrated nitric acid (volume ratio of 3:1), and after 6 hours of ultrasonic vibration treatment, slowly pour 500 ml of deionized water (with stirring), and let it stand After overnight, it was filtered and washed with deionized water until it became neutral, and dried in an oven. Repeat 3 times to obtain the carbon nanotube material after chemical etching. Weigh 100 mg of chemically etched carbon nanotubes and disperse them in absolute ethanol, and add 30 ml of KH-570 ethanol solution (concentration: 0.067 g / ml) dropwise in a water bath at 35°C. Keep the temperature and stirring speed constant, after continuous reaction for 40 hours, centrifuge and filter at 3400 rpm, re-disperse with absolute ethanol, repeat 5 times, vacuum dry at 40°C overnight to obtain coupling agent treatment carbon nanotubes containing double bonds. Add 50 mg of c...

Embodiment 2

[0030] Same as Example 1, but KH-570 changed to Wolan.

Embodiment 3

[0032] Same as Example 1, but KH-570 is changed to titanate coupling agent 5S.

Abstract

A nano-class carbon nanotubel polyvinyl imidazole composition is prepared from carbon nanotubes, polyvinyl imidazole, KH-570 or titanate 5S, trigger and emulsifier through chemical etching and mciroemulsion polymerizing. Said composition has high thermal stability, chemical stability, and excellent electric, dissolving, filming and photoelectric performance.

Description

technical field [0001] The invention belongs to the technical field of organic / inorganic nanocomposite materials, and in particular relates to a carbon nanotube / polyvinylimidazole nanocomposite material and a preparation method thereof. Background technique [0002] The study of carbon nanotube composite modified materials has become one of the hotspots in current materials research. So far, the composite modification methods of carbon nanotubes reported in the literature are generally divided into two categories. The first type is to use physical filling and coating methods to physically compound carbon nanotubes with metals or inorganic semiconductors. Although the mechanical and photoelectric properties of carbon nanotube materials have been improved, this method has complex processes and mechanical Poor performance and other disadvantages. The other is to obtain carbon nanotube / polymer composites by chemical modification or in situ polymerization. Although the process ...
