Problems solved by technology

[0003] Polyaniline endows the material with good electrical conductivity through protonic acid doping, although the presence of aromatic rings in the molecular chain of polyaniline helps to improve its heat resistance, however, conductive polyaniline doped with protonic acid, due to low molecular doping In the presence of dopant, its heat resistance is still poor, and the instability of small molecular dopants leads to the decomposition of polyaniline material at a lower stability. Therefore, how to improve the heat resistance temperature of polyaniline is very important for improving film quality. has a good promoting effect
