Description
Summary:Inkjet technology is utilized to deposit Ag-PEDOT:PSS thin films in this study. The obtained experimental results indicate that the addition of silver nanoparticles has improved the conductivity of PEDOT:PSS thin film up to two orders of magnitude, but as expected, a decrease in transparency simultaneously has occurred. The morphology of oxide on the surface of deposited PEDOT:PSS thin film has also been affected due to the introduction of the silver nanoparticles. However, application of preheating on the substrate has led to an anisotropic conductivity in the thin film possibly being observed as the coffee stain effect resulted from the uneven dispersion of the silver nano particles. It has been found that post baking process is not beneficial in terms of enhancement of the conductivity of such composite thin films.
