One kind of a sulfonated lignin-formaldehyde condensates acetone dispersion polymerization of 3,4-ethylenedioxythiophene and thiophene-conductive composite preparation and application-dioxo

The present invention belongs to the technical field of organic optoelectronic materials, discloses 3,4-ethylenedioxythiophene and thiophene-conductive composite dioxo one kind of preparation and application of sulfonated lignin-formaldehyde condensates acetone dispersion polymerization. The preparation method comprises: a sulfonated lignin-formaldehyde condensates formulated as aqueous acetone, 3,4-ethylenedioxythiophene monomer was added thiophene, mixing evenly, then added an aqueous solution of an oxidizing agent, the reaction was stirred for 5 to 48 hours at room temperature, the resulting the product was dialyzed to remove salts and unreacted monomers, to give the product. The present invention uses a sulfonated lignin-formaldehyde condensates of acetone as a dispersion carrier, the resulting conductive composite uniform and stable, high conductivity, high transparency material is applied as a hole exhibits a perovskite cell injection and commercial PEDOT: PSS comparable or better performance Youyou, a good prospect.
