This study describes and evaluates a low-temperature method for ambient-air plasma fabrication of hybrid titania/silica nanocomposite mesoporous layers that generate and transport electrons. The mesoporous layers were prepared using wet coating with a dispersion consisting of prefabricated titania nanoparticles and polysiloxane binder, subsequently inkjet-printed and plasma-processed by diffuse coplanar surface barrier discharge, to form an almost inorganic titania/silica coating of the high specific surface. The study demonstrates approaches to optimization of the coating, using various TiO

nanoparticles, and of the plasma processing, together with the economic significance of printing and plasma processing—an approach compatible with processes envisaged for the manufacture of flexible electronics.
