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
