Abstract:

This paper reviewed the research progress of porous poly(lactic acid) (PLA) materials in terms of molding process, pore structure modulation and performance optimization. Typical molding processes for porous PLA materials were introduced, including template method, non⁃solvent induced phase separation method, freeze⁃drying method and supercritical CO2 foaming method. The effects of different pore structures and variations in pore size and density on the properties were presented. In addition, the effect of stereo⁃complex crystal on the pore structure and macroscopic properties of porous PLA materials was emphasized.

Key words: poly(lactic acid), porous material, preparation process, structure and property, research progress
