Explanation

A general term for materials that mainly use other special physical, chemical or biomedical functions other than mechanical properties. It refers to materials that have special properties in electricity, magnetism, sound, light, heat, etc., or show special functions under their action. For example: magnetic materials, electronic materials, information recording materials, optical materials, sensitive materials, energy materials, damping material, shape memory materials, biotechnology materials, catalytic materials, special function film materials, etc. Different from structural materials, functional materials are commonly used to manufacture core components with unique functions in various equipment, and have important applications in automatic control, electronics, communication, energy, transportation, metallurgy, chemical industry, precision machinery, instrumentation, aerospace, national defense and other departments.
