Nano composite material of asymmetric phthalocyanine and carbon nano-tube and preparation method thereof

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 ...

AI Technical Summary

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 difficulty in controlling the degree of nanocomposite and poor thermal stability of nanocomposite materials.

In addition, so far, there are few reports on the preparation methods of asymmetric phthalocyanine / carbon nanotube nanocomposites

[0003] The invention utilizes a multi-step synthesis method and an in-situ reaction method to prepare a uniformly distributed and chemically stable asymmetric phthalocyanine / carbon nanotube nanocomposite material, which overcomes the difficulty of combining traditional phthalocyanine macromolecules on the surface of carbon nanotubes. Compact and easy to fall off and uneven distribution of phthalocyanine materials on the surface of carbon nanotubes, etc., and the present invention can significantly improve the photoconductivity of phthalocyanine / carbon nanotube composite materials, and obtain better photosensitivity
