Polyglycolic acid, also known as polyglycolic acid, is derived from α-hydroxy acid. Polyglycolic acid has a simple and regular linear molecular structure. It is a simple linear aliphatic polyester with high crystallinity and forms crystalline polymers. Crystallinity is generally 40% ~ 80%, melting point is around 225 C, insoluble in commonly used organic solvents.
Polyglycolic acid is a synthetic polymer material with good biodegradability and biocompatibility. Unlike traditional polymer materials, such as plastics and rubber, polyglycolide will gradually degrade and eventually become water and carbon dioxide that are harmless to environment. The application of polyglycolic acid is mainly manifested in two aspects of biomedicine and ecology.
The biomedical applications are mainly manifested in medical sutures, drug controlled release carriers, fracture fixation materials, tissue engineering scaffolds, and suture reinforcement materials.
The application in ecology is to replace the traditional plastic widely used in the plastics industry as a completely biodegradable plastic. Polyglycolide is mainly used as a slow-release system to control the rate of herbicide release.
The most advantage of using polyglycolide agricultural film is that it will not cause environmental pollution like the currently used polyethylene and polyvinyl chloride. This film can automatically degrade after several years of use and will not pollute the soil. Polyglycolide can also be used as water-retaining materials for forestry wood, aquatic materials and soil, desert greening.
