Nowadays, increasing attention has been devoted to transparent conductive films because of their various applications in Solar cells and OLEDs. 3D printing is an alternative promising fabrication process. The embedding of silver nanowires in a UV sensitive polymer matrix enables 3D printable conductive objects. Hence silver nanowires were synthesized via the polyol method resulting in an average diameter of approximately 130 nm and a length up to 100 μm. With optimization through dry etching sheet electrical resistance could be reduced to ca. 1.5 Ω/square. This is highly competitive with existing candidates such as indium tin oxide (ITO). As a next step layer systems consisting of UV cured 1,6-Hexanediol diacrylate (HDDA) and silver nanowires were prepared. The structure and morphology of the silver nanowire incorporated thin films were investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM), conductivity measurements and spectroscopic measurements. Inner film morphology was studied using grazing incidence small-angle X-ray scattering (GISAXS)
