[Brief description of the drawings]

[0013] The drawings described herein are provided to facilitate a deeper understanding of the present application, constitute a part of the application, and the schematic embodiments and description thereof are used to interpret the present application and are not intended to unduly limit the present application. [Figure 1] FIG. 1 is a step block diagram of the manufacturing method of the electrode microstructure of the present application. [Diagram 2] FIG. 2 is a schematic diagram of the electrode microstructure of the present application. [Diagram 3] FIG. 3 is another schematic diagram of the electrode microstructure of the present application. EXAMPLES

[0014] Hereinafter, several embodiments of the present application will be disclosed with reference to the drawings. For clarity, many implementation details will be described together below. However, it should be understood that these implementation details are not intended to limit the present application. That is, in some embodiments of the present application, these implementation details are not necessarily required. In addition, in order to simplify the drawings, some conventional structures and components are simply and diagrammatically shown in the drawings. In the following examples, the same reference numerals refer to the same or similar components.

[0015] Please refer to Figures 1 and 2. Figure 1 is a step block diagram of the manufacturing method of the electrode microstructure of the present application, and Figure 2 is a schematic diagram of the electrode microstructure. As shown in the figures, the present application provides a manufacturing method of the electrode microstructure 1, which includes the following steps S:

[0016] Step S100: Prepare a flexible plastic member 11. In this embodiment, the plastic member 11 is polyethylene terephthalate (PET), and the plastic member 11 is used as a base structure. The plastic member 11 can be folded to form a roll structure. The roll structure of the plastic member 11 is easy to handle in the subsequent related manufacturing processes.

[0017] Step S200: A surface structure layer 13 is sputtered on the surface of the plastic member 11 to form an electrode microstructure 1, the surface structure layer 13 being composed of a structure of one-dimensional metal nanocrystals, the surface structure layer 13 having a plurality of microstructures 131, the microstructures 131 being spaced apart from each other and distributed on the surface of the plastic member 11, each of the microstructures 131 having at least one pointed feature 1311, the pointed feature 1311 providing a pointed tip discharge.

[0018] In this embodiment, the plastic member 11 is treated by sputtering. Sputtering is a physical vapor deposition technique, which refers to a physical process in which atoms in a target material are bombarded by high-energy ions and separated into a gas. In sputtering, a high-voltage negative charge is introduced in a stable vacuum environment to cause dissociation in an inert gas to form plasma. The target material is placed at the cathode position, and the object to be sputtered is placed at the anode position. The cations of the ionized inert gas strike the surface of the target material, and the surface atoms of the target material are struck and deposited on the object to be sputtered, forming a surface structure.

[0019] In this embodiment, the target material includes copper tungsten, silver tungsten alloy, platinum, nickel fiber, nickel copper, iridium oxide, nickel iridium, copper iridium, or tin-antimony oxide. The sputtering target is a flexible plastic member 11, and the target material includes copper tungsten, silver tungsten alloy, platinum, nickel fiber, nickel copper, iridium oxide, nickel iridium, copper iridium, or tin-antimony oxide, and the like. The atoms of the target material are knocked out by the cations of the inert gas, and then the target material is deposited on the surface of the plastic member 11 to form a surface structure layer 13.

[0020] The surface structure layer 13 is made of a one-dimensional nanocrystal nanomaterial. The structure of the one-dimensional nanocrystal has three dimensions, namely, length, width, and height, and two dimensions, namely, width and height, are all nano-sized, and the height and width of the structure of the one-dimensional metal nanocrystal are between 1 nm and 50 nm. The shape of the one-dimensional nanocrystal includes, in addition to the pointed body 1311, a tube, a columnar, a wire, a strip, a needle, a spiral, and / or a ring.

[0021] As described above, in the process of gradually forming the surface structure layer 13 on the target material, the target material sputtered onto the surface of the plastic member 11 cannot form a perfect surface, that is, the state of the surface structure layer 13 sputtered onto the surface of the plastic member 11 cannot reach the structural condition in which two-dimensional metal nanocrystals form a perfect plane. In other words, the state of the surface structure layer 13 sputtered onto the surface of the plastic member 11 has the structural characteristics of an incomplete plane composed of one-dimensional metal nanocrystals.

[0022] Furthermore, the surface structure layer 13 is composed of a plurality of microstructures 131, and the plurality of microstructures 131 of the surface structure layer 13 are distributed separately on the surface of the plastic member 11, and the plurality of microstructures 131 have a block-shaped island-like structure, and the side edges of the microstructures 131 are not connected to each other.

[0023] Furthermore, when the microstructures 131 of the surface structure layer 13 are distributed on the plastic member 12, each of the microstructures 131 has at least one pointed body 1311. The pointed body 1311 of the microstructures 131 can provide a pointed discharge, and the sharper the conductive tip, the more prominent the pointed effect. This is because the higher the charge density on the surface of the part with a large curvature of the object surface (for example, the tip of a pointed, thin and small object), the stronger the electric field strength, thus enhancing the effect of electronic discharge. In other words, since the microstructures 131 are separated from each other, each of the microstructures 131 can be regarded as a structure that can discharge independently, and the pointed body 1311 of the microstructures 131 of the surface structure layer 13 can produce the effect of pointed discharge, strengthen the effect of electronic discharge, and improve the efficiency of the manufacturing process.

[0024] In this manner, the discharge action of the pointed bodies 1311 of the microstructures 131 of the surface structure layer 13 of this embodiment is useful for applications such as water electrolysis and material deposition, and can be used according to the needs of the user.

[0025] Furthermore, the surface structure layer 13 is an imperfect, planar, rough structure surface made of a one-dimensional metal nanocrystal structure, i.e., due to each of the cusp features 1311 of the microstructure 131, the surface of the surface structure layer 13 presents a three-dimensional uneven structure. The surface structure layer 13 made of one-dimensional metal nanocrystals has a larger surface area than a typical perfect plane, which is advantageous for providing a large surface area for reaction with the electroplating material for electroplating production, as mentioned above, and the rough structure surface of the surface structure layer 13 can also strengthen the bonding strength with the electroplating material.

[0026] 1 and 3, FIG. 3 is another schematic diagram of the electrode microstructure of the present application. As shown in the figure, in this embodiment, since the flexible plastic member 11 is used as a base, after the step S300: forming the electrode microstructure 1, the electrode microstructure 1 can be further wound to form a winding material 3, so that the surface of the electrode microstructure 1 having the surface structure layer 13 is wound on the outer surface 112 of the winding material 3. In addition, another surface structure layer can be fabricated on the inner surface 111 of another surface of the outer surface 112 of the plastic member 11 according to the needs of the user (not shown).

[0027] In summary, the present application provides a method for manufacturing an electrode microstructure and the electrode microstructure. A surface structure layer, which is an incomplete rough structure surface composed of a one-dimensional metal nanocrystal structure, is formed on a plastic member to form a large surface area. The surface structure layer comprises a plurality of microstructures, which are distributed on the surface of the plastic member, and each of the microstructures has at least one sharp tip. The sharp tip of such a microstructure can provide a sharp tip discharge, which can improve the efficiency of the subsequent electroplating manufacturing process, and can provide a large surface area for reaction with the electroplating material, while the rough structure surface of the surface structure layer can also strengthen the bonding strength with the electroplating material.
