Research Progress in Polylactic Acid Composite Materials

Polylactic acid, as a kind of degradable macromolecule materials, attracts extensive attention. However, the properties of polymer synthesized from lactic acid, such as mechanical strength, plasticity and so on, need be improved. Materials compounding is the method of improving the properties of polylactic acid. In this article, varieties and properties of composite materials with polylactic acid as the matrix were introduced, and their development prospect was discussed.
