摘要
聚乳酸(PLA)具有良好的生物降解性和生物相容性,被广泛应用于多个领域。直接熔融缩聚法改性PLA是一种既环保又高效地制备高性能PLA的途径,具有潜在的工业化应用价值。本文从改性物质、催化剂种类和聚合方式等方面综述了2010年以来,国内外直接熔融缩聚法改性PLA的研究进展,并指出未来研究中基于可持续发展的工业化应用方向值得关注。
Polylactic acid (PLA ) has good biodegradahility and biocompatibility, and is widely used in many fields. Modifying PLA by direct melt polycondensation (DMP) is an environmental and efficient way to prepare high-performance PLA which has potential industrial application value. In this paper, the research progress on the modification of PLA by DMP at home and abroad since 2010 has been reviewed from the aspects of modifying substances, catalyst types and polymerization ways in DMP. It is also pointed out that the research direction of industrial application based on sustainable development is worthy of attention in the future.
