Technology for 3D printing material based on carbon nanotubes (CNTs)
CNTs are of great interest in connection with their unique properties, such as extreme strength, special electrical properties, high efficiency when used as conductors of heat, corrosion resistance, etc. They are able to impart new properties to already known materials even with a small addition and are indispensable in the design of new composite materials, including those based on metals, plastics, and polymers. New composite materials with specified properties can be obtained by inserting a small amount of CNTs.
To improve the properties of materials, an effective chemical interaction between the CNTs surface and material matrix is required. Otherwise, the uniform mixing of CNTs with molten materials is practically impossible. To ensure the chemical interaction of materials with nanostructure surface, this surface must be modified.
