Description
Technical Field
The invention relates to the field of short circuit prevention of electrode materials, in particular to a method for preventing short circuit of a conductive electrode on the inner surface of a capillary or a special pipe.
Background
Electrochemical treatment is one of branches of chemical treatment, and is widely applied to the fields of energy, biology, environment, metal material surface modification and the like. The electrochemical reaction device generally comprises a power supply, a cathode, an anode, an electrolyte and the like. The cathode and the anode are made of conductive materials to ensure the conduction of system current. In an open system, the distance between the cathode and the anode is large and can be adjusted, and the contact cannot occur due to the action of external force (such as air bubbles floating upwards, the stress of the liquid flow action on the cathode and the anode, and the like) in the reaction process. However, for a semi-closed system (such as a capillary tube and a special-shaped tube) with limited area, the distance between the cathode and the anode is small, so that the cathode and the anode are easy to contact under the action of external force, and the short circuit between the cathode and the anode is caused, so that the reaction cannot be smoothly carried out. For example, when the inner surfaces of capillary tubes or special tubes such as capillary metal tubes, needle tubes for detection, heat dissipation copper tubes for mobile phones, spiral titanium tubes for condensation and the like are subjected to super-wetting modification by adopting an electrochemical reaction method, the capillary tubes or the special tubes are used as anodes, and cathode wires need to be arranged in the capillary tubes or the special tubes, but the prior art cannot ensure that the cathode wires and the capillary tubes or the special tubes are not short-circuited in the reaction process, and even super-wetting coatings are prepared on the inner surfaces of the capillary tubes or the special tubes. Therefore, it is urgently needed to develop a short circuit prevention method for the conductive electrode on the inner surface of the capillary tube or the special tube, which avoids short circuit, is convenient to operate, has wide applicability and is low in cost.

For example, the surface of the tube is treated by immersing the tube in an electrolyte, the penetrated electrode is used as a cathode or an anode, and the other electrode is a capillary tube or a special tube (the capillary tube, the special tube and the electrode are all made of conductive materials).
Further, the concentration of the high molecular polymer solution is 10 to 100g/L.

Further, the capillary tube or the special-shaped tube is a capillary metal tube, a needle tube for detection, a heat dissipation copper tube for a mobile phone or a spiral titanium tube for condensation.
Furthermore, the cleaning time of the electrode is 0.5-4 h, the drying temperature is 50-80 ℃, and the drying time is 2-5 h.
Further, after the high molecular polymer solution is coated, the temperature for drying the electrode is 50-80 ℃, and the drying time is 0.5-4 h.

Detailed Description
The present invention is further illustrated by the following examples, but it should not be construed that the scope of the above-described subject matter is limited to the following examples. Various substitutions and alterations can be made without departing from the technical idea of the invention and the scope of the invention is covered by the present invention according to the common technical knowledge and the conventional means in the field.
Example 1:
in the method for preventing short circuit of the conductive electrode on the inner surface of the capillary or the special pipe, a molecular polymer solution with polyvinylidene fluoride as a solute and N-methylpyrrolidone as a solvent, the concentration of which is 10g/L, needs to be prepared.
The method comprises the following steps:
(1) Sequentially carrying out ultrasonic vibration cleaning on a stainless steel wire electrode with the diameter of 0.2mm in a detergent, alcohol and deionized water for 0.5h respectively;
(2) Drying the stainless steel wire by using a nitrogen spray gun;
(3) Drying the stainless steel wire at 50 ℃ for 1h;
(4) Repeatedly coating the high molecular polymer solution on the surface of the dried stainless steel wire serving as a substrate, wherein the coating times are 20-25;
(5) Drying the stainless steel wire coated with the polyvinylidene fluoride solution at the drying temperature of 50 ℃ for 2h;
(6) Stainless steel wires are penetrated into a dry capillary titanium tube with the inner diameter of 0.4mm, a power supply is connected, and electrolyte is introduced for electrochemical treatment (anodic oxidation treatment).
The relevant performance data for this example is as follows:
in the comparative experiment, the uncoated, 0.2mm diameter stainless steel wire, which is a metal, alone as the cathode in the anodic oxidation process, left only 0.2mm due to the remaining space in the tube. When the electrolyte is introduced, the electrolyte has a scouring effect on the cathode stainless steel wire, so that the cathode stainless steel wire is easy to contact with the anode capillary titanium tube to cause short circuit. As shown in fig. 2, by coating a high molecular polymer film, the outer surface of the treated cathode stainless steel wire is coated with a high molecular polymer diaphragm with a thickness of about 20-30 μm, and the diaphragm can separate the anode and the cathode during anodic oxidation, so as to prevent short circuit and not shield an electric field, so that anodic oxidation can be performed. As shown in FIG. 3, the length of the titanium dioxide nanotube array prepared by anodic oxidation is about 3 μm, and the titanium dioxide nanotube array has the characteristics of smooth tube wall, good opening and the like. FIG. 4 presents statistics of the lengths of nanotube arrays at different positions on the inner surface of the capillary titanium type tube, and illustrates that the thickness of the prepared nano-coating is uniformly controllable. Meanwhile, the method has the advantages of convenient operation, wide application range, low cost and the like.
