Thin Layers of TiO2 Prepared by Inkjet Printing

journal article - other

English

In this letter, we demonstrate the benefits of using inkjet printing technology for the preparation of TiO2 thin layers. By utilizing the well know sol-gel chemistry used so far for spin- and dip coated layers of TiO2 together with the wide deposition possibilities offered by inkjet printing, we are able pro prepare thin layers of TiO2 in a very effective and clean way with minimum waste. The structure of prepared layers greatly depends on the printing conditions: If the sol ejection rate is faster then solvent evaporation, a smooth compact layer is produced. On the other hand, when the solvent evaporation rate is grater than sol ejection, we obtain highly structured and porous layer.
