Popis We report on the influence of post-printing curing on the physico-chemical properties of silica-bonded particulate titania photocatalytic layers. Ink consisting of commercial titania nanoparticles and a novel siloxane binder was patterned by inkjet printing. Printed layers were mineralized by three processes: thermal annealing by convection heating in an electric furnace, UV-curing with a high pressure mercury vapour lamp, and atmospheric plasma treatment in a coplanar dielectric barrier discharge. The influence of these processes on the extend of the binder mineralization and resulting physicochemical properties, charge generation and transport as well as photocatalytic activity was investigated. All curing methods proved to be capable to mineralize the binder but atmospheric plasma curing stands out as the fastest one enabling a direct implementation into roll-to-roll fabrication processes.
