Effect of DMF and DMSO on the PEDOT: PSS inkjet ink properties

Poly(3,4-ethylenedioxythiophene): poly styrene sulfonic acid (PEDOT:PSS) is one of the conductive polymers that is useful in the optoelectronic devices such as light emitting diodes and solar cells. In this research, inkjet inks based on the PEDOT:PSS were formulated with DMF and DMSO as a co-solvent. The printability and post printing properties of prepared inks were investigated. The prepared formulations were compatible with inkjet printer. The results show that dimethylformaldehyde is improved the ink-jet printed PEDOT:PSS ink properties. .
