Research on the Printability of Pearl Inkjet Photo Paper with Nano-copper Flexography Ink

摘要

With the fast development of information science and technology, printed electronics technology obtains great potential for application on flexible electronics. Printing electronics has many advantages, such as low cost, low energy consumption, green environmental protection and other features. Printed electronics abandoned conventional "subtraction" etching process and applied "additive" printing process, thereby reducing the waste of materials and pollution. The rise of printing electronics has also contributed to the development of conductive ink. This research aimed to the printability of nanoscale copper ink on pearl inkjet photo paper. By using the nano-copper conductive ink which is fabricated on our lab, the conductive layer was coated and printed on the photo paper. Then the microscopic characterization of the pearl inkjet photo paper was carried out to reveal the surface topography. At last, the microscopic characterization of the pearl inkjet photo paper with copper layer was conducted to analyze the printability, including the testing of adhesion and drying speed. This work could be beneficial for the development of flexible electronic devices.
