Development prospect of functional materials;
The research of functional materials in the world is very active, full of opportunities and challenges, and new technologies and patents emerge one after another. Developed countries try to form a technical monopoly in the field of special functional materials through intellectual property rights, and try to occupy the vast market of China. This situation has aroused great concern in China.
China has strengthened patent protection in the fields of new rare earth permanent magnets, biomedicine, eco-friendly materials, catalytic materials and technologies. However, we should see that China's innovative research on functional materials is not enough, and the number of patent applications, especially the number of international original patents, is still far from commensurate with China's status. The functional materials in China also have shortcomings in system integration, which need to be improved and developed.
