Problems solved by technology

The conductivity of polyaniline itself is not high, and it needs to be doped to improve the conductivity. However, polyaniline is more difficult to process in the later stage. Affected by processing difficulty and processing cost, the conductivity of polyaniline composite materials is not very high. Ideal, but the processing cost also needs to be reduced
[0003] As a field of rapid prototyping, 3D printing technology can be applied to the preparation of conductive parts with special requirements for precision and shape, but the current printing materials cannot be used to realize the production of conductive parts

Description

technical field [0001] The invention belongs to the field of precision casting technology, and in particular relates to a 3D printing material used for producing conductive parts. Background technique [0002] As one of the conductive polymer materials, polyaniline is considered to be the structural conductive polymer with the most commercial application value because of its good chemical stability, good weather resistance, cheap and easy-to-obtain raw materials, simple synthesis method, and electrical conductivity. Power technology and other fields have huge market demand. The conductivity of polyaniline itself is not high, and it needs to be doped to improve the conductivity. However, polyaniline is more difficult to process in the later stage. Affected by processing difficulty and processing cost, the conductivity of polyaniline composite materials is not very high. Ideal, while processing costs also need to be reduced. [0003] As a field of rapid prototyping, 3D print...
