Polylactic acid (PLA) is one of the most extensively studied biodegradable materials. PLA is a versatile material with excellent bio-compatibility, bioabsorbability, biodegradability, and low toxicity. As an environmentally friendly polymer, PLA is favored by researchers and has explored many commercial applications, playing an important role in medicine and industry to replace many traditional petrochemical-based polymers. However, the strength and mechanical properties of PLA need to be improved to meet the practical application of multiple scenarios. The purpose of this review is to explore the modification methods of grafted copolymerization and block co-polymerization to improve the performance of PLA. This review also focuses on the medical applications and covers some non-medical applications of PLA.
