Method for preparing metal structure on surface of transparent material by using metal nanometer ink

Abstract

The invention discloses a method for preparing a metal structure on the surface of a transparent material by using metal nanometer ink. The transparent substrate is put into the metal nanometer ink, the substrate is irradiated by lasers, and by controlling the parameters of the lasers and the material and concentration of the ink, the metal material in the metal nanometer ink is selectively separated out at a laser focus point of the surface of the substrate, and finally a metal micro-nanometer structure is prepared on the surface of the transparent substrate. According to the preparation method, preparation is directly conducted in the liquid phase, the lasers can directly reach the surface of the substrate, metal particles in the metal nanometer ink are sintered into a metal layer capable of conducting electricity stably, the preparation process is simplified, the metal oxidation rate in the preparation process is low, and the metal layer with the controllable size is selectively formed at the laser focus point; and the problems that the metal particles are deposited at and adsorbed by the whole body of the surface of a base material are prevented, the raw materials are saved, the energy consumption is lowered, accordingly the production cost is lowered, and the method has the great market prospects and the economic value.

Description

technical field [0001] The invention belongs to the field of laser processing, and relates to a laser printing method, in particular to a method of using metal nano-ink to carry out laser printing on the surface of a transparent material. Background technique [0002] At present, devices based on transparent materials have been widely used in the technical fields of optics, consumer electronics, biomedicine and micro-opto-electro-mechanical systems. The preparation of metal structures on the surface of transparent materials is a relatively common modification method, and the methods used mainly include: (1) conventional deposition method and (2) laser deposition preparation method. In the preparation of surface micro-nano structures of transparent materials, laser direct writing has unique advantages, such as no need for vacuum, which can reduce costs and simplify the processing process.

Problems solved by technology

However, among the two existing methods, the laser transfer method has the problems of relatively complicated preparation process and low production efficiency. The commonly used laser direct sintering method has a high oxidation rate and needs to increase the drying steps, resulting in large loss of raw materials and energy consumption. large and costly
