Degradation mechanism, characteristics and application of biodegradable materials.

Definition and degradation mechanism of biodegradable materials
Biodegradable materials, also known as "green ecological materials", refer to materials that can be degraded under the action of soil microorganisms and enzymes. Specifically, it refers to polymer materials that can cause biodegradation under certain conditions under the action of natural microorganisms such as bacteria, molds, and algae.

The ideal biodegradable material is a polymer material that has high performance and can be completely decomposed by environmental microorganisms after being discarded, and finally converted into CO2 and H2O to become a component of the carbon cycle in nature.

The decomposition of biodegradable materials is mainly through the action of microorganisms. Therefore, the degradation mechanism of biodegradable materials is the process of digestion and absorption of materials by bacteria and molds.
