Abstract

The invention belongs to the field of an electronic material, and relates to a preparation method for a cellulosic paper-based flexible high-conductivity pattern. According to the preparation method provided by the invention, the cellulosic paper is taken as the substrate; a wax-painting printing technology is combined with a chemical plating technology to directly design and print the required metal patterns; the specific process comprises the steps of cleaning the surface of the cellulosic paper, performing surface modification, performing surface patterning and waxing, performing surface activation, performing electroless copper plating, removing wax from the surface, and the like. The preparation method has the following advantages that (1) the required waxed pattern is directly designed and printed on the surface of the cellulosic paper, so that the operation is simple and easy to implement; (2) the preparation method is low in cost; the process is simple and convenient; the metal pattern is convenient to design; and the various kinds of conductive patterns can be designed according to requirements. The cellulosic paper-based flexible high-conductivity pattern prepared by the invention can be applied to flexible display, electronic tags, electronic antennas and other new technological products, and has a quite bright market prospect in the future.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a preparation method of a cellulose paper-based high-conductivity pattern. Background technique [0002] The printed electronic device industry has developed rapidly in recent years. The substrates of traditional printed electronic devices mostly use hard substrates such as silicon substrates and glass substrates. Patterned printed electronic devices can be obtained by using techniques such as etching or screen printing on the substrate. However, these methods often have the disadvantages of complex manufacturing process, high cost, low utilization rate of materials, and serious waste. With the development of printed electronics, printing technology came into being and was quickly applied to the preparation of electronic devices. However, the current printing process of printers is cumbersome, highly dependent on instruments and equipment, and has many r...
