Photocatalytic and Selfcleaning Properties of Titania Coatings Prepared by Inkjet Direct Patterning of a Reverse Micelles Sol-gel Composition

Abstrakt

A reverse micelle sol-gel composition based on titanium butoxide, Triton X-102 and xylen was optimized for deposition by inkjet printing. Sol deposition and direct patterning onto commercial ITO-coated glass plates was successfully performed by a dedicated experimental inkjet printer Fujifilm Dimatix DMP-2831. Printed layers were dried and gelled at 110 C for 30 min and calcined in an furnance at 450 C for 4 hours. However, two distinctive processing ways were adopted for the multilayered samples: Single calcinated series of samples was prepared by printing 1 to 4 layers of sol and single final gelling and calcination. Repeatedly calcined samples were prepared by repeated printing, gelling and calcination after printing each layer.
