Study on the Radiation Resistance of PI Silver Plated Film in Radiation Environment

brief introduction

With the development of aerospace and nuclear energy technology, there is an increasing demand for materials that can work stably in high radiation environments. Polyimide (PI) films are widely used in electronic devices in extreme environments due to their excellent thermal stability and mechanical properties. This article conducted experimental research onPI silver plated filmThe radiation resistance performance under different doses of radiation irradiation was studied, and the possibility of maintaining stable performance under radiation environment was explored.

The radiation resistance of materials is crucial in spacecraft, satellites, and other applications that require exposure to cosmic rays or other strong radiation sources. PI silver plated film has a wide range of application prospects in flexible electronic devices due to its good conductivity and transparency. However, radiation may have a negative impact on the properties of materials, making research on their radiation resistance particularly important.

Experimental Materials and Methods

This study usedAdvanced Institute (Shenzhen) Technology Co., LtdThe provided PI silver plated film sample. The experiment is mainly divided into the following parts:

Firstly, ensure that all samples have the same thickness and silver plating quality for subsequent testing data comparison. Then, the sample was subjected to varying degrees of irradiation using a gamma ray source (such as Co-60), with the test dose range gradually increasing from zero to 100 kGy, to simulate different radiation environments.

Next, the conductivity, optical transparency, and mechanical properties of the samples will be tested before and after irradiation. The conductivity test uses the four probe method to measure the resistivity of the sample; The optical transparency is measured by a UV visible spectrophotometer; Mechanical performance testing evaluates the tensile strength of the sample through a tensile testing machine.

experimental result

The experiment found that with the increase of irradiation dose,PI silver plated filmThe conductivity of the material shows a slight upward trend. At an irradiation dose of 10 kGy, the conductivity increased by approximately 2% compared to the non irradiated state, while at 50 kGy, this value reached 5%. When the dose was further increased to 100 kGy, the conductivity increased by about 8%.

The trend of changes in optical transparency is opposite. In the initial state, PI silver plated film has high optical transparency. After irradiation with 10 kGy, the transparency slightly decreased by approximately 1%; When the irradiation dose increased to 50 kGy, the transparency decreased by 5%; At a maximum dose of 100 kGy, the transparency loss reached 10%.

For mechanical properties, as the irradiation dose increases, the tensile strength of PI silver plated film shows a decreasing trend. At a radiation dose of 10 kGy, the tensile strength decreased by approximately 3%, while at 50 kGy it decreased by 10%. When the dose reached 100 kGy, the tensile strength decreased by 15%.

In addition, the surface morphology changes of PI silver plated film were observed under different irradiation doses in the experiment. The results showed that with the increase of irradiation dose, slight cracks and peeling phenomena appeared in the silver layer, which may be one of the reasons for the decrease in optical transparency and mechanical properties.

discuss

The experimental results indicate that althoughPI silver plated filmTo a certain extent, it can withstand radiation, but its performance will still be affected in high-dose radiation environments. The improvement in conductivity may be due to radiation induced rearrangement between silver particles, forming more conductive channels. However, the decrease in optical transparency and mechanical performance limits its application in high radiation environments.

conclusion

PI silver plated film can still maintain good performance stability under low-dose radiation, but its optical transparency and mechanical strength will decrease under high-dose radiation environment. Future research will focus on developing new coating technologies and improving PI substrates to further enhance the radiation resistance of PI silver plated films and ensure their reliable use under extreme conditions.
