Embodiment 1

[0019] Embodiment 1: Print silver film on PET (polyethylene terephthalate) substrate The conductive ink consists of the following solutions: silver ammonia solution and formaldehyde solution. Wherein, the composition of silver ammonia solution is as follows:

[0020] Silver nitrate 60g

[0021] Ammonia 60ml

[0022] Distilled water 1L

[0023] The composition of the formaldehyde solution is as follows:

[0024] Formaldehyde 65mL

[0025] Distilled water 1L

[0026] The container for storing the silver ammonia solution is directly connected with a nozzle of the inkjet printer. The container for storing the formaldehyde solution is connected with another nozzle of the inkjet printer.

[0027] On the cleaned PET (polyethylene terephthalate) substrate, first print the silver ammonia solution on the substrate with an inkjet printer, and then print the formaldehyde solution in the same pattern to form a layer of metal on the surface of the bottom layer. Floor. Wash the surfa...

Embodiment 2

[0028] Example 2: Printing a copper film on glass

[0029] Conductive ink consists of the following solutions: copper salt solution, formaldehyde solution. Wherein, the composition of copper salt solution is as follows:

[0030] Copper Sulfate (CuSO 4 ·5H 2 O) 16g

[0031] Sodium Potassium Tartrate (NaKC 4 h 4 o 6 4H 2 O) 14g

[0032] Sodium hydroxide (NaOH) 14g

[0033] Distilled water 1L

[0034] The composition of the formaldehyde solution is as follows:

[0035] Formaldehyde 15g

[0036] Distilled water 1L

[0037] The container for storing the copper salt solution and the container for storing the formaldehyde solution are directly connected to the same nozzle of the inkjet printer.

[0038] On the cleaned glass substrate, the inkjet printer prints two solutions simultaneously on the substrate, forming a metal layer on the surface of the bottom layer. Wash the surface of the substrate with deionized water to remove the reaction product and unreacted solution...

Abstract

The invention provides a group of ink for printing a conductive film and a use method thereof, which can be used for manufacturing circuit components, circuit leads, antennae of radio-frequency circuits, and the like. The invention adopts the technical scheme that at least two kinds of solutions are sprayed to generate a metal film on a substrate through a chemical reaction. The metal film generated after the chemical reaction has good conductibility and can be used as a circuit component, a lead or an antenna. The method has lower requirement for the substrate material and can greatly reduce the manufacturing cost of circuits, and the generated film is dense and has strong adhesive force.

Description

technical field [0001] The patent of the present invention relates to the ink for making conductive film and its use method, which can be used to make electronic components, wires and antennas. Background technique [0002] Printed Electronics (Printed Electronics or Printable Electronics) is used to describe the technology of printing electronic circuits on some commonly used media such as paper, plastic or fabric. Ideally, printed electronics employ some common printing methods such as screen printing, letterpress printing, gravure printing, and lithography. Printed electronics enable some special applications that cannot be achieved with traditional electronic circuits, such as bendable flexible displays, smart labels, posters that can play animation and active clothing. [0003] Printed electronics technology uses special ink to print electronic devices, and the development of conductive ink is a recent development hotspot. Conductive inks can be used to print passive ...
