摘要
综述了多孔聚乳酸(PLA)材料在制备工艺、孔结构调控和性能优化等方面的研究进展.介绍了多孔PLA材料的典型制备工艺,包括模板法、非溶剂诱导相分离法、冷冻干燥法和超临界CO2发泡法.同时,介绍了不同孔结构以及孔尺寸和密度的变化对性能的影响.此外,重点介绍了立构复合晶(SC)对多孔PLA材料孔结构和宏观性能的影响.
Abstract
This paper reviewed the research progress of porous poly(lactic acid)(PLA)materials in terms of molding pro-cess,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 proper-ties of porous PLA materials was emphasized.
