| Abstract: | Poly lactic acid is a kind of polyester. It can be degraded into carbon dioxide and water in nature, which do no harm to the environment. Its degradation is resulted from the cleavage of ester bond. The indirect degradation mechanisms of PLA are investigated. The factors affecting degradation are summarized. The development prospect of poly lactic acid is also discussed in the end. |
