Problems solved by technology

Among them, the common polymer conductive materials include polypyrrole, polyaniline and polythiophene. Among them, polypyrrole has good electrical conductivity, mechanical flexibility, biocompatibility, and almost no pollution to the environment. It has great potential in the field of sensors and capacitors. Wide application prospects; common fabric wool fiber has good hygroscopicity, and the moisture regain can reach 16%. However, due to the scale layer on the surface of the wool fiber, the hydrophilicity of the wool fiber is poor. Easy to generate charge, which limits the application of wool fiber to a certain extent
