Description of the invention (1) Field of invention < Please read the notes on the back before filling out this page) The present invention relates to a method for synthesizing nickel wire, especially a nickel wire using redox Chemical synthesis method. BACKGROUND OF THE INVENTION In the past few years, nickel metal has been widely used in industry. It is mainly used for the preparation of mechanical alloy materials, ceramic materials, magnetic materials and catalysts. In electronic products, nickel-gold is also used in conductive adhesives, EMI shielding, and antistatic materials. Whether in conductive adhesives or electromagnetic interference shielding materials, nickel metal is used as a conductive filler. When the concentration of such a conductive filler in the matrix reaches a critical threshold, the resistance will drop drastically, causing the overall material to change from an insulator to a conductor. This critical threshold is called the percolation threshold. However, when such conductive fillers are blended with resin or plastic, the criticality of the fillers tends to increase due to the poor mixing effect. Therefore, in order to control the quality during the manufacturing process, In general, the particle charge of commercial products reaches more than 70% by volume, but the increase in particle charge means an increase in cost. Printed by the Shelley Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs According to reports in the literature, the method for reducing the critical volume of metal particles roughly includes: improving the mixing method of the metal and the matrix, and using a powder with a larger surface area (in other words, using finer particles) Powder), or particles with a high aspect ratio, such as flake or fiber or filament particles. At present, the synthesis methods of metal powder materials include physical synthesis and chemical synthesis-4-This paper size applies to Chinese national standards (CNS > A4 specification (210 X 297 mm) I 4 5 0857 A7 i B7 V. Description of the invention (2) There are two major types of physical methods: physical synthesis methods such as pulverization method and sputtering method. Chemical synthesis methods include sol-gel method, vapor deposition method and redox method. Take nickel as an example. In the patent, there is no description of the nickel wire manufacturing method, but only the method of nickel powder synthesis. In the nickel powder synthesis method, the common synthesis method is generally a precursor that reduces the nickel by passing a gas at a high temperature, such as US patents 4,673,430; 5,584,908; 3,850,612. The T-ray irradiation reduction method uses Co6 ° as a radiation source. After irradiation to NiS04 aqueous solution, nickel ions can be reduced to generate nickel metal particles. The characteristic of this method is that 0H radicals must be additionally added Scavenger, the purpose is to avoid the oxidation of monovalent nickel ions into divalent ions in the reaction of the solution phase, otherwise the yield will decrease = In addition, increasing the pH of the reaction solution will also help to increase the yield The records in the literature are:

Description of the invention (4) As for the synthesis method of nickel wire, the commonly used method in the industry is: (a ) After the nickel metal is melted, it is directly drawn. However, it requires a high heating temperature, and the drawn wire does not have a too small diameter.

When the volume fraction of nickel in the synthesized nickel wire is 94%, the diameter of the nickel wire is 0.4 μm and the length can reach 100 jum, but its prerequisites are required. The use of carbon fibers will also be limited by the size of the carbon fibers. Moreover, when using the electroplating method, it is difficult to obtain very uniform results because of the electric field distribution. In addition, the nickel wire produced in this article still has a carbon core 1 so its conductivity is relatively pure nickel. The silk was poor. The main purpose of the nickel wire synthesized in this article is the electromagnetic wave shielding (EMI) effect. According to the theory, the smaller the diameter of the metal wire, the better the effect.

More preferably, the nickel wire has a diameter of 0.5 to 5 microns and a length of 0.5-50 mm. Consumption by employees of the Intellectual Property Bureau of the Ministry of Economic Affairs The cooperative prints the first example. 10 ml of a solution containing nickel ions, including 0.45M KHC03, 0.65M N2Η4.Η20, 0.50M K2C03, 0.10M NiCl2.6H20, 0.50 \ 1 of 1 ;: 21 ^ 〇 4 and 0.25M KOH, mixed with 8ml of deionized water in a 100ml beaker, and placed in a preheated 80 ° C water bath, which was placed in a PMC 500 series model 502 multi-point hot plate and agitator And control the temperature between 80-90 ° C (PMC 500 series analog hotplate-stirrers Model No. 502 from Barnstead / Thermolyne, Iowa, US). While the cup was heated in an 80t environment, 2 ml of 98% N2H4_H20 (hydrazine hydrate) and 0.0046 g (7.98xlO_4M) of sodium dodecylbenzene sulfonate (SDS) were immediately added. After heating for 10 minutes, the color of the solution changed from light blue to dark blue. At this time, nickel wires gradually formed. After heating for 20 minutes, the solution became colorless. At this time, the reaction was estimated to be complete. The yield reached 90% or more. Most of the generated nickel wire was deposited on the bottom of the container, and a small portion of the synthesized nickel wire was still floating on the upper layer of the solution. After the reaction mixture is filtered and the solid obtained is dried, the nickel wire can be obtained. The nickel wire synthesized in this example is observed by an electron microscope to have a length of several hundred microns or more and a diameter ranging from micrometers to submicrons. In the meantime, as shown in the scanning electron microscope (scan electron microscopy 'SEM') picture of FIG. There are many long strips of crystals on the surface of the nickel wire, as shown in the SEM photo of Figure 2. 11- This paper size is in accordance with Chinese standards (CNS > A4 specification (210 * 297 public love)) Page order ▲ 450857 A7 B7 V.

This sample Specific surface area is about 2.73 m2 / g »Example 2 In this example, we changed the reaction temperature to observe the growth of nickel wires at different temperatures. The solution composition here is the same as in Example 1. The so-called reaction Completion time refers to the moment when the solution changes from blue to colorless. The reaction results are as follows: (Please read the precautions on the back before filling out this page) Group reaction Maede reaction completion time Zhensi special RT1 60- 70 ° C 150 minutes to form a complete network structure RT2 80-90 ° C 20 minutes Nickel wire length can reach several centimeters RT3 100-110 ° C 12 minutes on the multi-faceted total wall, a few grow into filaments Order: Ministry of Economic Affairs Printed by Intellectual Property Bureau Staff Consumer Cooperatives When the reaction temperature is between 60-70 ° C, all the nickel wires grow with a nucleation center at a certain place at the bottom of the reactor, and grow into a network structure. * No nickel wires are suspended in the upper layer of the solution. When the reaction temperature Between 80-90X :, the synthesized nickel wire also takes a certain bottom of the reactor as the nucleation center, but some of the nickel wires are suspended in the upper layer of the solution. This phenomenon should be caused when the nickel wire grows, because the speed is relatively high. Fast, so that the diameter of some nickel wires is small. After being subjected to the convection of the solution, it is easy to break into short nickel wires suspended in the upper layer of the solution. When the reaction temperature increases to 100-UOt, the reaction takes 5 minutes. The wall of the vessel is plated with nickel. After the reaction is completed, most of the nickel produced is ammonium on the vessel wall, and a small part is grown into nickel wires, which are connected to the nickel plated on the vessel wall. The scale applies to the CNS A4 specification (210 X 297 mm) A7 B7 5. From the description of the invention (10), it is obviously not ideal reaction conditions. This example shows that when the reaction temperature is too high , The reaction accelerates, causing nickel to oversaturate, which promotes Nucleation on the wall of the device yielded results similar to silver mirrors. In this set of experiments, the yield of RT1 was 86.9%, and the specific surface area of the sample was 11.8 m2 / g. Example 3 The purpose of this example is to illustrate the difference in SDS For the formation of nickel wire at a concentration, the synthesis procedure and conditions are the same as in Example 1. The only change is the concentration of the surfactant SDS. The concentration of the surfactant SDS is between 1M0 · 4-8 × 10 · 3M.

The part of the generated nickel wire is suspended in the upper layer of the solution, and the part is connected with the bottom of the reactor somewhere, that is, the junction should be the nucleation center of the nickel wire. However, in the SC5 and SC6 groups, the reaction time is shorter, and most of the reduced nickel is plated on the wall of the reactor. -13- This paper is applicable to national standards (CNS > A4 specifications) (210 * 297 mm) 4δ〇8 57 Α7 B7 i. Description of the invention (11) Only a small amount of nickel exists in the form of nickel wire, which shows that if the amount of SDS added is too low, the reaction rate will be reduced, such as In addition to the longer reaction time, the length of the nickel wire formed in the SC2 group is also shorter. However, the addition amount should not be too much, otherwise it will promote the nucleation effect, as shown in the SC5 and SC6 groups. SCI and SC4 The yields were 81.7% and 92.5%, respectively, and the specific surface area of the SC4 sample was 7.3 m2 / g. Example 4 The surfactant used in the first three examples is an anionic surfactant. The effect is to increase the reaction rate, but when the concentration is too high, there is a silver mirror reaction. In this example, the synthesis procedures and conditions are the same as in Example 1, except that we use cationic and nonionic interface activities.剂。 Made in this example The cationic surfactant is C16TABr (hexadecyltrimethyl-ammonium bromide): the non-ionic surfactant is Tween80 (polyoxyethylenesorbitan monooleate ).

Description of the invention (12) Adding both C16TABr and Tween 80 In terms of material, obviously the concentration increases Accelerate the reaction. In the lower concentration group, the reaction rate is slower than when it is not added. • However, the nickel wire generated is partially suspended in the upper layer of the solution, and some is nucleated at a certain position at the bottom of the reactor. In the center, it grows into a structure of nickel wire, but there is no phenomenon of plating on the reactor wall. Therefore, when the finished nickel wire is collected by filtration and drying, it is easy to collect and has a large amount. When the concentration is increased, the reaction rate is significantly faster, but most of the reduced nickel is plated on the reactor wall, and only a small amount of nickel wire is generated. The above data shows that if the reaction rate is too fast, the ideal nickel wire cannot be obtained as a product. Slowing down the reaction rate, although nickel wire can still be obtained, it is probably not conducive to the production rate. The yield here is about 82-86%, and the specific surface area of the first group is 10.0 m2 / g. Example 5 This example shows the growth of nickel wires under different reducing agent (diamine) concentrations. The synthesis procedure and conditions are similar to those in Example 1, in which the total volume of the solution is fixed at 20 m, and the concentration of hydrazine is changed by adjusting the volume of deionized water. The reaction temperature was controlled at 80-90 ° C without adding any surfactant.

The purpose of the addition is to form a stable hydrazine in solution. Carbonate (hydrazine carboxylate), in order to avoid the reduction reaction of nickel and nickel ions in advance during storage. The function of potassium carbonate is to help stabilize hydrazine carbonate in solution. If there are no carbonate ions in the solution, precipitation of nickel hydroxide will obviously occur, but this has no effect on the formation of nickel wires, which can be known from the results of ELC2. At the same time, it also shows that nickel hydroxide is an intermediate product of the reaction process, so any salt of nickel * such as nickel chloride, nickel nitrate, etc., as long as nickel hydroxide is added to the alkaline solution, it should be similar. result. However, if no phosphate ion is added as a buffer, the reaction will be significantly accelerated, making the nickel wire extremely short, as shown by ELC3, which also indicates that the pH of the solution should also be an important experimental parameter.
