Abstract: The research progress in flame retardant polymer materials at home and abroad in recent years was reviewed. The flame retardant methods, such as adding flame retardants, chemical reaction, surface modification, alloying, nano-compounding, and synergizing, were introduced. The characteristics of the various methods were analyzed. The developing trend of flame retardant methods for polymer materials was envisioned.

Key words: polymer material, flame retardant method, synergistic flame retardancy, developing trend
