Performance changes and coping techniques of PI aluminum plated film in high magnetic field environment

With the rapid development of technology, PI aluminum plated filmDue to its excellent comprehensive performance, it has been widely used in fields such as electronics, electrical engineering, and aerospace. However, in high magnetic field environments, the performance of PI aluminum plated film may be affected to some extent. This article will explore the performance changes of PI aluminum plated film in high magnetic field environment, and propose corresponding response technologies based on the research results of Advanced Institute (Shenzhen) Technology Co., Ltd., in order to provide reference for related fields.

PI (polyimide) aluminum coated film is a high-performance composite material that combines the high temperature resistance, chemical corrosion resistance, and excellent mechanical properties of PI thin films with the high conductivity, high reflectivity, and barrier properties of aluminum coatings. This material performs well in fields such as electronic and electrical packaging, optical reflectors, and electromagnetic shielding. However, in high magnetic field environments, its performance may change, affecting its application effectiveness.

In high magnetic field environments, the electromagnetic shielding performance of PI aluminum plated film may be affected to some extent. Due to the high conductivity of the aluminum layer, it generates eddy currents in a magnetic field, which affects the shielding effect. In addition, the conductivity of the aluminum layer may change due to an increase in magnetic field strength, which in turn affects its shielding performance.

The high magnetic field environment may indirectly affect the mechanical properties of PI aluminum plated film. For example, eddy currents in a magnetic field may cause an increase in surface temperature of materials, which in turn affects their mechanical strength and flexibility.

The high magnetic field environment itself has an impact on PI aluminum plated filmThe chemical stability of the aluminum layer is less affected, but the magnetic field may synergize with other environmental factors such as humidity and temperature to accelerate the oxidation of the aluminum layer. The formation of an oxide layer will reduce the conductivity and reflectivity of the aluminum layer, thereby affecting its overall performance.

Advanced Institute (Shenzhen) Technology Co., Ltd. has improved the adhesion and uniformity of the aluminum layer by optimizing the aluminum plating process. For example, using vacuum evaporation technology combined with surface treatment processes ensures that the aluminum layer can maintain good conductivity and shielding performance in high magnetic field environments.

Regarding the potential oxidation issues that may occur in high magnetic field environments, Advanced Institute (Shenzhen) Technology Co., LtdDeveloped antioxidant coating technology. By adding an antioxidant coating on the surface of the aluminum layer, the oxidation process can be effectively slowed down and the service life of the material can be extended.

To address eddy current issues in high magnetic field environments, a multi-layer structural design can be adopted. For example, adding a layer of highly conductive material outside the aluminum layer to quickly guide eddy currents, while the inner layer uses high absorbing materials to absorb electromagnetic wave energy.

By adjusting the material formula, adding magnetic elements or changing the particle size distribution of magnetic particles, the performance of materials in high magnetic field environments can be improved. This method can effectively reduce the possibility of magnetic saturation and improve the electromagnetic compatibility of materials.

PI aluminum plated filmIn high magnetic field environments, there may be issues such as decreased electromagnetic shielding performance, changes in mechanical properties, and decreased chemical stability. However, by optimizing the aluminum plating process, antioxidant treatment, multi-layer structure design, and material formulation optimization, these challenges can be effectively addressed. The research achievements of Advanced Institute (Shenzhen) Technology Co., Ltd. in related fields provide strong support for the application of PI aluminum plated film in high magnetic field environments.

In the future, with the development and application of more new technologies, PI aluminum coating is expected to play a greater role in high magnetic field environments, providing more reliable solutions for fields such as electronics, electrical, and aerospace.
