Abstract

The method for preparing metal oxide function film by using ink-jet printing process includes the following steps: 1). using soluble metal compound as raw material, dissolving it in water or organic solvent, the weight ratio of raw material and water or organic solvent is 1-30:100-200; or dispersing nano granules of metal oxide in water or organic solvent according to same weight ratio; 2) addingadditive, added quantity is 0.01-5% of weight of water or organic solvent, the controlled ink viscosity is 20-60 mPa.s and its surface tension is 20-40 mNm(-1), and preparing metal oxide ink with stable property; 3). injecting said ink into ink box and adopting conventional ink-jet printing process to make the ink deposit on the substrate; and 4). heating film layer deposited on the substrate at 200-700 deg.C to form the metal oxide functional film.

Description

technical field [0001] The invention relates to metal oxide thin film technology, in particular to a method for preparing a metal oxide functional thin film by inkjet printing. Background technique [0002] Metal oxides have many special physical and chemical properties, and the preparation of metal oxide thin film materials with certain structures, compositions and patterns is the basis of many modern functional devices. At present, lithography and thick film printing are mainly used to prepare functional material thin films with specific patterns. The lithography technology first adopts thin film preparation processes such as vacuum coating to prepare thin films, and then uses photolithography and chemical etching to prepare specific patterns. Thick film printing technology first prepares the template and material slurry, then prints on the substrate, and then sinters to obtain the film layer. These techniques all require the preparation of templates, expensive equipment...
