Degradable materials are materials that can be degraded in the sense of thermodynamics and kinetics over a period of time. According to the external factors of degradation, it can be divided into: photodegradable materials, biodegradable materials, etc. The influencing factors mainly include temperature, molecular weight , and material structure.
According to the external factors of degradation, it can be divided into:
-
Photodegradable materials: degraded due to sunlight;
-
Biodegradable materials: due to the respiration or chemical energy synthesis of natural microorganisms such as fungi and bacteria, they are degraded and finally decomposed into carbon dioxide and water;
-
Environmentally degradable materials: degrade under the action of natural environmental conditions such as light, heat, water, polluting compounds, microorganisms, insects, and mechanical forces.
