Preparation Method of Nanowires Copper Composite Powder
Nanowires copper composite powder is a kind of nanomaterial with a wide range of applications. These nanomaterials have superior performance in terms of electrical conductivity, mechanical strength and heat resistance. In this article, a preparation method of nanowires copper composite powder is described.
The preparation of nanowires copper composite powder requires the use of two traditional chemical processes. The first is electroplating, which utilizes an electrical current to deposit a thin layer of copper on an object’s surface. The second is electrochemical oxidation, which uses an oxidizing agent to form the nanowires on the surface of the object.
The first step in preparing the nanowires copper composite powder is to prepare the starting material. The starting material must be small particles of the desired metal, such as copper, or other metals. The particles must be of a consistent size and shape.
In the next step, the particles must be immersed in an electrolyte solution which contains a salts and/or anodic agents. The electrolyte will create an electrical current that will cause the particles to become positively charged. This charge attracts the electrolyte, which will form a thin coating on the surface of the particles.
The third step is to add an oxidizing agent to the electrolyte. This will cause the particles to react with the oxidizing agent, forming the nanowires on their surfaces. The nanowires can then be collected from the surface of the particles and separated from the electrolyte as needed.
The fourth step is to recover the nanowires from the surface of the particles. There are two ways in which this can be done. The first is to use a mechanical process such as screening, which involves passing the particles with nanowires attached through screens of different sizes. The second is to use an electrochemical process such as electrochemomechanical separation, which involves using a reverse electric field to separate the nanowires from the particles.
Finally, the nanowires with copper must be annealed. This process involves heating the material so that the copper in the nanowires will become homogeneous and uniform. Once the annealing is complete, the nanowires copper composite powder can be collected and ready for use.
In summary, the preparation of nanowires copper composite powder involves the use of two traditional chemical processes. This includes electroplating, in which a thin layer of copper is deposited on the surface of particles, and electrochemical oxidation, in which an oxidizing agent forms nanowires on the surface of the particles. The nanowires can then be recovered from the particles and annealed to make the copper in the nanowires more homogeneous and uniform. When the annealing is complete, the nanowires copper composite powder is ready for use.
