A Study on modification of polylactic acid and its biomedical application

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