Preparation method and application of sulfydryl-containing sulfonated chitosan and poly (3, 4-ethylenedioxythiophene) complex

The invention discloses a preparation method and application of a sulfydryl-containing sulfonated chitosan and poly (3, 4-ethylenedioxythiophene) complex, according to the method, the solubility of PEDOT (poly (3, 4-ethylenedioxythiophene)) in an aqueous solution is increased by introducing sulfonated chitosan, then sulfydryl functionalization is carried out on SCS, and the sulfydryl-containing sulfonated chitosan and poly (3, 4-ethylenedioxythiophene) complex is obtained. The sulfydryl functional groups include but are not limited to disulfide bonds in lipoic acid and N-acetyl-L-cysteine or other functional groups containing-SH,-CHO and the like, and finally the sulfydryl-containing sulfonated chitosan and poly (3, 4-ethylenedioxythiophene) complex is prepared. According to the complex, the water solubility is improved, meanwhile, the application range of the complex in special demand scenes is widened, and especially when the complex is used for preparing a hydrogel material, the conductivity and the adhesi
