Description
Technical Field
The invention relates to the field of printed electronic device preparation, in particular to a method for regulating and controlling stray particles at the edge of an ink-jet printing metal wire by using ultraviolet light.
Background
After the particle type ink is released and deposited by a point-jet piezoelectric ink-jet printing technology, the particle distribution of the particle type ink is one of the main factors influencing the electrical properties of the film.
Due to the development limitation of the short-channel electrode ink-jet printing direct imaging technology, the regulation and control of the microscopic stray particles at the edge of the metal wire in the existing process of printing the metal wire by using the particle type ink-jet printing still does not give enough attention. In the current short channel electrode implementation: (1) laser ablation techniques, the resulting metal lines are generally smooth-bounded and free of stray particles: (2) the substrate is pre-patterned by hydrophilic and hydrophobic treatment or a deposited film, and because the boundary of the ink-jet printing metal wire is limited by using the method, the liquid material is also free of stray particles after being solidified; (3) the method utilizes the coffee ring effect to form adjacent thin lines, and stray particles can exist between the thin lines at the time, and the regulation and control means relate to the optimization of ink components and a solidification sintering process.
The above technique has some drawbacks: (1) the use of laser ablation techniques is generally not suitable for the construction of multilayer-structure electronic devices; (2) the substrate is subjected to hydrophilic and hydrophobic treatment or the deposited film is subjected to pre-patterning, so that the process steps and the cost of the inkjet printing non-vacuum process are increased to a certain extent, and the advantages of the inkjet printing electronic device are not favorably embodied; (3) the adjacent thin lines are formed by utilizing the coffee ring effect, certain requirements are put on ink-jet printing ink, a substrate and a printing environment, and the line width of the ink-jet printing metal lines is difficult to continuously adjust.
With the innovation of ink-jet printing technology, the short-channel electrode can be directly patterned, but the free boundary of the printed metal wire using the particle-type ink can form stray particles, which affects the electrical stability of the ink-jet printing electronic device.
