Abstract

The invention discloses vanadium dioxide ink for inkjet printing. The vanadium dioxide ink is prepared from the following components: nano vanadium dioxide powder, a dispersing agent, a bonding agent and a diluent, wherein the diluent is a mixed solution of dimethylbenzene and ethyl acetate or a mixed solution of the dimethylbenzene and butyl acetate. A preparation method of the vanadium dioxide ink disclosed by the invention comprises the following steps: carrying out mixed ultrasonic dispersion on the nano vanadium dioxide powder and the diluent to obtain vanadium dioxide dispersing liquid; carrying out mixed dispersion and grinding on the vanadium dioxide dispersing liquid and the dispersing agent in a sand mill; then adding the bonding agent, and continuously grinding in the sand mill until the materials are uniformly mixed, thus obtaining the vanadium dioxide ink for the inkjet printing. According to the vanadium dioxide ink disclosed by the invention, by regulating and controlling the particle size, stable dispersion, viscosity and surface tension of the nano vanadium dioxide ink, the vanadium dioxide ink suitable for the inkjet printing is successfully prepared; according to the nano vanadium dioxide ink disclosed by the invention, the smoothness of an inkjet printing process is ensured, a liquid drop shape can be formed during printing, a good printing effect is realized, and the requirement on film forming property of a printer is met.

Description

technical field [0001] The invention belongs to the field of ink, and in particular relates to a vanadium dioxide ink used for inkjet printing, a preparation method and application thereof. Background technique [0002] Vanadium dioxide is a functional material with thermally induced phase change properties. Its phase transition temperature is around 68°C. When the temperature is lower than 68°C, VO 2 It is a monoclinic phase structure, showing the characteristics of an insulator; when the temperature is higher than 68 ° C, VO 2 Transforms into a rutile structure, exhibiting metallic properties. VO 2 The sudden change of resistivity before and after phase transition can reach 4 orders of magnitude, and the sudden change of emissivity in infrared band can reach 0.6, which has important research value in the fields of smart windows and infrared camouflage and stealth. Vanadium dioxide mainly includes two kinds of film and powder. Compared with film, vanadium dioxide powder ...
