For example, by improving the molecular structure and gold plating process of polyimide, the high temperature resistance and conductivity of the material can be enhanced; By introducing new additives such as nanoparticles, the mechanical strength and chemical corrosion resistance of the material can be further enhanced. These technological innovations will enable the application of high-temperature resistant PI gold plating films in a wider range of fields.
**3.2 Expansion of Application Fields**
In addition to fields such as aerospace, automotive electronics, and military equipment, high-temperature resistant PI gold plating film also has great potential for application in emerging fields such as new energy and intelligent manufacturing. For example, in new energy vehicles, high-temperature resistant PI gold plating film can be used for circuit connections in battery management systems; In the field of intelligent manufacturing, it can serve as one of the core materials for high-precision sensors and actuators. With the rapid development of these emerging fields, the market demand for high-temperature resistant PI gold plating film will continue to grow.
**3.3 Considerations for Environmental Protection and Sustainable Development**
In today's society, environmental protection and sustainable development have become a global consensus. As a high-performance material, high-temperature resistant PI gold-plated film also needs to consider environmental factors in its production and application process. For example, by using environmentally friendly polyimide resin and gold plating technology, harmful substance emissions during the production process can be reduced; By recycling and reusing waste high-temperature resistant PI gold-plated film materials, resource consumption and environmental pollution can be reduced. These environmental measures will help promote the sustainable development of the high-temperature resistant PI gold plating film industry.
**Conclusion**
