Abstract: With the increasingly serious problems in plastic pollution， degradable plastics have been receiving attention gradually. However， the rapid and accurate detection of the effectiveness and safety of degradable plastics becomes a crucial issue. In this paper， several techniques for the rapid detection of degradable plastic structures， such as spectroscopic analysis and nuclear magnetic resonance spectroscopy， were reviewed. The purpose of this review was to provide assistance for the rapid structural detection of degradable plastics and also to facilitate market regulation. In the future of rapid detection technology， it is necessary for degradable plastics to improve the accuracy and sensitivity of detection and also to develop more practical and environmentally friendly detection methods to provide an effective technical support for the production， applications， and post?treatment of degradable plastics.

Key words: degradable plastics, nuclear magnetic resonance, spectrum analysis, thermal analysis, quick detection
