Inkjet Printing of Thin Dielectric Films Based on BaTiO3

Abstract

BaTiO3 thin films have been prepared by inkjet depositing of ceramic inks based on barium titanate nanopowder. Formulated inks had good sedimentation stability. The most significant stabilization of the pigment was observed for samples formulated on ethyl and n-butyl alcohols. All prepared inks had dilatant flow with a pronounced minimum viscosity of Newtonian flow. The printing operation was performed using thermal drop-on-demand inkjet printer. Printed films had dense structure and considerable adhesion to the substrate surface. Optical profilometry of the three layer film showed thickness about 400 nm. Due to strong adhesion printed coatings have not separated from the substrate surface. Special method of forming an intermediate polymer film on the substrate surface has been used to separate printed patterns. Aggres-sively dissolving of an intermediate polymer film has been observed during printing on this intermediate layer. After printing of each subsequent layer substrate thickness has been reduced on average 200 nm and took place rising of surface roughness. However, printed layer has been removed from the substrate surface. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35225
