With the increasingly extensive application of polymer materials,the problem of environmental pollution caused by polymer waste is becoming increasingly prominent.The development and application of degradable polymer mate-rials is one of the effective ways to solve the problem of environmental pollution.Based on the principle of photodegradation and biodegradation,the synthetic degradable polymer materials are divided into photodegradable materials,biodegradable materials and photobiodegradable materials according to the degradation mechanism.The characteristics of various polymer materials are introduced.At present,the market application of various materials and the existing problems in the develop-ment and production of degradable polymer materials are reviewed.Finally,the development direction of degradable polymer materials is put forward.
