Abstract

The invention provides a poly N-vinyl-gamma-PVSA modified water-soluble carbon nano tube and a preparation method thereof, which is characterized in that under the high-temperature and high-pressure hydrothermal condition, polyvinyl pyrrolidone (PVP) and the carbon nano tube generate pi-pi conjugation to obtain a PVP non covalent bond coated carbon nano tube; then, under the alkali condition, thePVP on the surface of the carbon nano tube generates hydrolysis reaction to generate the poly N-vinyl-gamma-PVSA; and the strong hydrophilic carboxylic acid anion in the hydrolysate is used for improving the dispersionstability of the carbon nano tube in water so as to greatly improve the water solubility of the carbon nano tube. The carbon nano tube preparation method provided by the invention has the advantages of environment protection, high efficiency, low cost and simple technology, can accelerate large-scale preparation and industrialization of the water-soluble carbon nano tube and hasgreat application prospect in fields, such as nano science, material science, chemical industry and biomedicine.

Description

technical field

[0001] The invention relates to the preparation of water-soluble carbon nanotubes, in particular to a water-soluble carbon nanotube modified by poly-N-vinyl-γ-aminobutyrate sodium and a preparation method thereof. Background technique

[0002] In the last ten years, carbon nanotubes (CNTs) have achieved major breakthroughs in many fields of application due to their unique structure, excellent mechanical properties, and functional properties such as light, electricity, and heat. Show more potential applications, such as bioengineering, materials science, catalytic chemistry, physical chemistry, biochemistry and other fields, so it is a new hotspot in nanoscience research. Due to their high specific surface energy, carbon nanotubes are more likely to agglomerate and are insoluble in water. Therefore, their application in some hydrophilic environments, such as bioengineering, biochemistry, etc., is greatly restricted, and it is necessary to carry out a hydrophil...
