Improvement of Chemical Copper and Nickel Plating Processes in the Preparation of Polyester/Metal Composite Transparent Conductive Films

1、 The necessity of chemical copper and nickel plating processes

Polyester/metal composite transparent conductive filmThe application in the field of optoelectronics is becoming increasingly widespread, and the chemical copper and nickel plating processes in its preparation are crucial for improving the conductivity and stability of the film. Although traditional chemical copper and nickel plating processes can achieve conductivity of the film to a certain extent, there is still room for improvement in terms of uniformity, adhesion, and corrosion resistance. Therefore, the improvement of chemical copper and nickel plating processes is urgent and of practical significance.

2、 Limitations of existing processes

Currently, polyester/metal composite transparent conductive films face the following challenges in chemical copper plating and nickel treatment: difficulty in controlling the uniformity of coating thickness, detachment caused by insufficient adhesion, and poor corrosion resistance. The existence of these problems limits the performance of polyester/metal composite transparent conductive films in practical applications.

3、 Improvement plan and implementation

1. Optimize the formula of chemical copper plating and nickel solution

Optimizing the composition of chemical copper plating and nickel solutions is key to addressing the limitations of existing processes. By adjusting the concentration of the main salt, the type and concentration of the reducing agent, and the selection of the chelating agent, the uniformity of the coating can be improved and the adhesion can be enhanced. For example, introducing specific stabilizers and complexing agents into copper plating solutions can effectively suppress the occurrence of side reactions, thereby improving the quality of the coating.

2. Introduce advanced surface treatment technologies

Surface treatment technology is an important factor affecting the effect of chemical copper plating and nickel plating. By adopting advanced surface treatment techniques such as sandblasting, plasma treatment, or UV induced polymerization, the roughness and polarity of the substrate surface can be improved, thereby enhancing the adhesion between the coating and the substrate. For example, through plasma treatment technology, the active groups on the surface of polyester can be activated, making it easier to bond with the coating.

3. Adjust the parameters of the chemical plating process

The influence of adjusting process parameters on the effect of electroless copper plating and nickel plating cannot be ignored. By controlling parameters such as plating temperature, time, and pH value, optimization of coating thickness, density, and structure can be achieved. For example, in the process of electroless nickel plating, appropriately increasing the temperature and pH value can promote the reduction reaction of nickel ions, thereby improving the thickness and conductivity of the coating.
