A composite thin film and its application

Abstract

This invention belongs to the field of polymer materials and relates to a composite film containing a substrate layer and a functional layer, and its applications. The functional layer of the composite film contains metal regions and organic compound regions. The organic compounds in the organic compound regions have high stability and are fluorine-free. Furthermore, while maintaining high stability, they also improve the overall resistance to damp heat, achieving the beneficial effects of efficient production, improved performance, and environmentally friendly products.
