High-Performance Transparent PEDOT: PSS/CNT Films for OLEDs

Abstract: Improved OLED systems have great potential for next-generation display applications. Carbon nanotubes (CNTs) and the conductive polymers poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) have attracted great interest for advanced applications, such as optoelectronic products. In this paper, the simultaneous enhancement of the conductivity, roughness, and adhesion properties of transparent conductive films with PEDOT: PSS/CNTs is reported. These films prepared by a simple spin-coating pro… Show more

“…By contrast, the value of the Au-ECNT/PEDOT:PSS films (D) was superior to that of Au-ECNT films (in Tables S1 and S2), which might be explained by the synergistic effect between PEDOT:PSS and the CNTs . The existence of PEDOT:PSS plays a role in lowering the contact resistance between the CNTs and boosting the electron mobility of the whole film, while the presence of CNTs is conducive to connecting the structural domains of PEDOT:PSS. , Simultaneously, the chemical and thermal stability of the films was also enhanced. , Table presents the optoelectronic values of the Au-ECNT/PEDOT:PSS (D, E) films. The optoelectronic values of Au-ECNT/PEDOT:PSS (D, E) films above 34 in the transmittance range of 70.3–91.3% were slightly higher than those of Au-ECNT/PEDOT:PSS (D) films, and on the basis of DMSO-doped PEDOT:PSS to improve its conductivity, further treatment of the films in the EG bath achieved the effect of removing more insulating PSS and improving the transmittance, as expected, and a decrease in the sheet resistance of the films, and thus an overall increase in the optoelectronic properties of the films.…”

“…coupled with the selected donor side group, thiophene, by means of Suzuki reaction giving 3-(4-ethenylphenyl)thiophene (St-D). Benzo[c] [1,2,5]thiadiazol, selected as an acceptor unit, was attached to MA in a two-step process, consisting of amidation with an amine derivative, followed by ring closure in the presence of acetic anhydride to obtain the final N-(benzo[c] [1,2,5]thiadiazol-5-yl)pyrrole-2,5-dione (Ma-A) (see Scheme 1). The structure and purity of both synthesized monomers were confirmed by recorded NMR and IR spectra (see Figures S1-S5 in Supplementary Materials).…”

“…The development of conjugated polymers (CP) is of particular importance to the solution of crucial worldwide challenges as they have found application in many various devices, such as solar cells [1], light-emitting diodes [2], energy storage [3], sensors [4], wearable equipment [5], and implantable devices [6], which can address health-, environment-, or energy-related issues. Such a wide spread of application fields is determined mainly by advantages of conjugated macromolecules, which include primarily low costs [7], flexibility [5], and facile processability [8].…”

“…3,4 Replacing the rigid-like substrates with elastomers yields truly flexible and stretchable devices. [5][6][7] Such mechanically compliant devices have been used in bioelectronics, [8][9][10] robotics, 11,12 solar cells, 13,14 and organic electrochemical transistors (OECTs). [15][16][17][18] An overarching component that enables these devices is poly (3,4-ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) courtesy of its intrinsic conductivity, high degree of transparency in the visible spectrum, and solution processability.…”
