Progress in Material Analysis of Biodegradable Materials.

Biodegradable material is a kind of polymer material which has no pollution to the environment. It has been used in food packaging, medical treatment, agriculture and other industries. However, the production cost of biodegradable materials is high and the physical properties are defective, which affects their wide application in various fields. The types and properties of biodegradable materials are reviewed. The advantages and disadvantages of spectroscopy, nuclear magnetic resonance and chromatography and mass spectrometry in the identification of biodegradable materials are compared. It is pointed out that the material characterization of biodegradable materials and the analysis methods of impurities are the key research contents, so as to provide reference for the material analysis of biodegradable materials.
