Problems solved by technology

The first type is to use physical filling and coating methods to physically compound carbon nanotubes and phthalocyanine materials. Although the solubility and photoelectric performance of carbon nanotube materials are improved, this method is easy to operate but has the advantages of phthalocyanine materials. Molecules are not tightly bound and easy to fall off on the surface of carbon nanotubes, and the uniform distribution of phthalocyanine materials on the surface of carbon nanotubes cannot be controlled.
The other is to obtain phthalocyanine/carbon nanotube composites by chemical modification or chemical reaction, although the dispersion uniformity and processability of carbon nanotubes in solvents can be significantly improved, and the size of nanocomposites can be further improved. However, this method also has problems such as diffic

Example Embodiment

[0018] Example 1

[0019] Add 100mg of multi-walled carbon nanotubes to a mixed strong acid solution composed of 100ml of concentrated sulfuric acid and concentrated nitric acid (volume ratio of 3:1). After overnight, it was filtered and washed with deionized water until neutral, and placed in an oven to dry. Repeat 3 times to obtain the carbon nanotube material after chemical etching. 100 mg of activated carbon nanotubes were placed in a 150 mL single-neck round bottom flask, 12 mL of silane coupling agent KH-550 and 50 mL of toluene were added, and the mixture was refluxed at 130 °C for 10 h. The carbon nanotubes were filtered out, washed with methanol and acetone in turn, and then dried under vacuum at 150° C. to obtain surface-treated carbon nanotubes. Weigh 100mg of the above surface-treated carbon nanotubes and disperse them in 30mL of freshly distilled N,N'-dimethylformamide, and at room temperature, add 1.73g (10mmol) of 3-nitrophthalic acid in batches and 3.0 g of ...

Example Embodiment

[0020] Example 2

[0021] Same as Example 1, but the silane coupling agent KH-550 is changed to hexanediol

Example Embodiment

[0022] Example 3

[0023] It is the same as Example 1, but the silane coupling agent KH-550 is changed to hexamethylenediamine.

Abstract

A nanometer composite material of asymmetric phthalocyanine and carbon nanometer tube and its production are disclosed. The process is carried out by reacting organic small-molecular chemically modified carbon nanometer tube with nitro-substituted phthalic nitrile monomer to obtain carbon nanometer tube with phthalic nitrile group, in situ reacting it with phthalic nitrile monomer to obtain final product. It's tight and homogeneous, it has excellent dissolving, filming and photoelectric performances. It can be used in conductive, luminescent, solar battery and transistor industries.

Description

technical field [0001] The invention belongs to the technical field of organic / inorganic nanocomposite materials, and specifically relates to an asymmetric phthalocyanine and carbon nanotube nanocomposite material and a preparation method thereof. Background technique [0002] The research on organic / inorganic nanocomposites based on phthalocyanine / carbon nanotubes has become one of the hotspots in current material research. So far, the preparation methods of phthalocyanine / carbon nanotube nanocomposites 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 and phthalocyanine materials. Although the solubility and photoelectric performance of carbon nanotube materials are improved, this method is easy to operate but has the advantages of phthalocyanine materials. Molecules are not tightly combined and easy to fall off on the surface of carbon nanotubes, and ...
