Flexographic printing of PEDOT:PSS on coated papers for printed functionality

Large area printed conductive surfaces are expected to have an impact on printed functionality ranging from electronics to photonics such as printed solar cells. We report here a study on formation of such conductive surfaces by flexographic printing using a PEDOT:PSS conductive ink on various coated papers. Printability of multilayer coated paper and TiO₂ nanoparticle coated paperboard generated by the liquid flame spray process are compared to plastic film typically used in printed functionality applications. The wettability of TiO and superhydrophilic states by ultraviolet light. It is observed that superhydrophobicity of paperboard induced by TiO₂ nanoparticle coating can be altered between superhydrophobic nanoparticles results in poorer ink setting with the water-based PEDOT:PSS yielding lower conductivities. Therefore, we observe conductivity only after several successive prints. A solvent-based silver ink was used for comparison. It is believed that renewable natural fibre based substrates, such as coated paper meeting criteria for sustainable development will find more applications in the future.
