but it still faces many problems.

pga (polyglycolic acid), also known as polyglycolic acid and polyglycolide, is a linear aliphatic polyester polymerized by glycolic acid and has a high degree of crystallinity. pga (polyglycolic acid) has excellent biodegradability, biocompatibility, heat resistance, gas barrier properties and mechanical strength. it is a synthetic polymer material with good biodegradability and biocompatibility. different from traditional polymer materials with stable performance such as plastics and rubber, pga…
