Abstract

The invention pertains to the field of inks for an inkjet printer, particularly relates to a method for preparing an inkjet water-soluble ink containing noble metal nano particles. The method for preparing an inkjet water-soluble ink containing noble metal nano particles comprises the following steps: noble metal nano particles, a water soluble cosolvent, a polymer dispersant, a surfactant and redistilled water are stirred and mixed, then predispersion and concentration are conducted and the inkjet water-soluble ink containing noble metal nano particles is obtained. The ink can be further added with an alkalinity and acidity buffering agent used for adjusting the pH value of the ink so as to keep the pH value of the ink between 7 and 10. The ink can replace inks in the market and various lines and models of electronic devices can be printed on paper, transparent film base and silicon chips through daily used inkjet printers. The inkjet water-soluble ink containing noble metal nano particles can be used for the lines of micro electronic devices and micro electronic machinery system as well as the production of microfluidic chips and bioreactors.

Description

technical field [0001] The invention belongs to the field of inks for inkjet printers, and particularly relates to a preparation method of an inkjet water-soluble ink containing precious metal nanoparticles. Background technique [0002] With the continuous development of electronic technology, the advantages and disadvantages of inkjet printer products are constantly highlighted. Its main advantages are low price, low noise, convenient replacement of ink cartridges or ink filling, low cost, and can provide good full-color printing quality. It can be directly printed on different carriers such as general paper, special printing paper, special transparencies and silicon wafers. The disadvantage is that compared with laser printers, the response time is longer and the printing speed is slower. In the present invention, the inkjet printer is preferentially used due to the unique advantages of replacing the ink cartridge or the convenience of ink filling. [0003] Colorants in...
