一种基于激光制备电极的方法

本申请提供一种基于激光制备电极的方法，涉及电子器件技术领域，该方法包括：通过原料制备基底材料，其中原料包括聚二甲基硅氧烷和有机盐，有机盐包括有机铜盐或有机镍盐，聚二甲基硅氧烷和有机盐的质量比在11：0.1～11：6之间；激光按预设轨迹照射基底材料，以在基底材料表面形成对应预设图案的微蚀刻结构；将具有微蚀刻结构的基底材料浸没在金属镀液中，以在微蚀刻结构上沉积金属并形成电极。本方法利用激光将有机盐中的金属阳离子还原成金属单质作为催化剂，金属镀液中的金属阳离子在催化剂的化学作用下，沉积在微蚀刻结构上以形成电极。本方法制备的电极连续性和导电性良好，可用于柔性基底表面的图案化电极的无掩膜制备。

The application provides a method for preparing an electrode based on laser, and relates to the technical field of electronic devices. The method comprises the steps that a substrate material is prepared through raw materials, wherein the raw materials comprise polydimethylsiloxane and organic salt, the organic salt comprises organic copper salt or organic nickel salt, and the mass ratio of the polydimethylsiloxane to the organic salt ranges from 11: 0.1 to 11: 6; the laser irradiates the substrate material according to a preset track so as to form a micro-etching structure corresponding to a preset pattern on the surface of the substrate material; and the substrate material having the micro-etching structure is immersed in a metal plating solution to deposit metal on the micro-etching structure and form the electrode. According to the method, metal cations in the organic salt are reduced into metal elements to serve as a catalyst through the laser, and the metal cations in the metal plating solution are deposited on the micro-etching structure under the chemical effect of the catalyst to form the electrode. The electrode prepared by the method is good in continuity and conductivity, and can be used for maskless preparation of the patterned electrode on the surface of a flexible substrate.
