【Abstract】 With the development of computer technology and molecular structure theory, simulation technology plays an increasingly important role in the synthesis and modification of polylactic acid materials. In this paper, the application of simulation technology in the modification of polylactic acid materials in recent years is reviewed. It mainly includes molecular dynamics simulation, thermodynamic simulation, compatibility simulation, finite element analysis and degradation simulation.Through the simulation of molecular structure, energy and mechanics,, the molecular behavior, thermodynamic properties, compatibility,mechanical properties and degradation behavior of polylactic acid materials can be deeply understood. Future simulation research should focus on improving the accuracy and reliability of models, while applying multiple simulation methods for the same research object and combining them with experimental verification to better guide the modification research of polylactic acid materials.更多还原
