LeiPoly

The spinning solution is prepared by mixing the polymer PANI with a suitable solvent. A dopant is also added to impart conductivity. This process converts the non-conjugated molecular structure of PANI into a conjugated form through doping. The fibers are extruded using wet spinning in a solvent in a system specifically designed for temperature-sensitive polymers. The fiber is precipitated in a coagulation bath, and the remaining solvent is washed out in a subsequent washing and stretching bath. More…
