Carbon nanotube dispersion

Carbon nanotubes have become a highly promising one-dimensional nanomaterial due to their extremely high aspect ratio and strong mechanical properties. Their applications have involved various aspects such as nanoelectronic devices, catalyst carriers, electrochemical materials, hydrogen storage materials, and composite material reinforcement. The super strong mechanical properties of carbon nanotubes can greatly improve the strength and toughness of composite materials; The unique conductivity and optoelectronic properties can improve the conductivity of polymer materials and prepare new types of optoelectronic polymer composites; Its unique structure can be used to prepare one-dimensional nanocomposites filled with metals or metal oxides. However, carbon nanotubes have fewer surface defects and lack active groups, resulting in low solubility in various solvents. In addition, there is a strong van der Waals attraction between carbon nanotubes, coupled with their huge specific surface area and high aspect ratio, which causes them to form agglomerations or entanglements, disrupting the excellent mechanical and electrical properties exhibited by a single carbon nanotube, seriously restricting its application. Therefore, the effective dispersion of carbon nanotubes has become an essential step in practical applications.

The carbon nanotube dispersion solution prepared by our company uniformly disperses the powder after dispersion modification in a water-based (oil-based) system, forming a liquid with good dispersion and stability. It does not layer or precipitate, and is easy to add to other systems, solving the problem of difficult dispersion for customers. This product is widely used in industries such as ceramics, coatings, and electronics.

Technical indicators:

Carbon nanotube dispersion does not undergo re aggregation under high temperature, strong acid, or strong alkali conditions. This product can be added to plastics, ceramics, and other materials to provide conductivity or anti-static properties, increase strength and toughness. It can also be applied to numerous plastic films, ceramic surfaces, fibers, and other surfaces to provide conductivity or anti-static properties. The surface carbon nanotube coating adheres uniformly and firmly, and can be waterproof and oil resistant.

Carbon nanotube dispersion can also be implanted into textile fabrics, with a black surface that can effectively reflect 80% of the radiation effect. Under the irradiation of the sun, compared with similar black fabrics, the temperature can be reduced by about 3 ° C-5 ° C, and the surface resistance is around 105 ohms, which can effectively prevent static electricity. After multiple rubs and washes, it will not change. Can be made into radiation resistant clothing, maternity clothing, high-temperature work clothes, etc.
