Abstract: Dimethyl sulfoxide (DMSO), known as a “universal solvent”, is not only used routinely in chemistry, medicine, cosmetics and other fields, but also has its own applications in the field of organic electronics. Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS), as a conductive polymer materials with excellent water dispersion, has the advantages of excellent machinability, miscibility, biological compatibility, film-forming property and commercial scale production, and is widely used in antistatic coating, organic solar cells, biological sensors, and other areas of the new materials and green energy. DMSO plays an important role in regulating the properties of PEDOT:PSS films, such as morphology, conductivity, thermoelectricity, power function, interface contact, mechanics, and self-healing. Based on the research results of our team, other domestic and foreign scholars in this field, this paper systematically reviewed the effect and mechanism of DMSO on PEDOT and its derivative:PSS (PEDOTs:PSS), and discussed the problems and challenges in the application.

Key words: dimethyl sulfoxide, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid), conducting polymer, organic electronics, green energy
