| 摘 要： | 综述了国内外以聚乳酸（PLA）为基础的完全生物降解共混体系的研究进展，主要包括不同光学活性的PLA共混、PLA与脂肪族聚脂共混、PLA与天然高分子共混、PLA与聚己内酯共混、PLA与聚乙二醇共混、PLA与聚乙烯醇共混以及PLA与聚乙烯基吡咯烷酮共混等。目前的研究表明，将PLA与另一种完全生物降解组分共混，通过不同组分分子间的相互作用，使PLA材料在保持环境友好性的同时提高了力学性能、增加了韧性、并降低了生产成本等，从而扩展了PLA在工程塑料领域和包装等领域的应用。

| Abstract: | Biodegradable polymer blends based on polylactide (PLA) were reviewed, including blends of enantiomeric polylactides, PLA/ aliphatic polyester, PLA/ natural polymers, PLA/ poly(ε-caprolactone), PLA/ poly (ethylene glycol), PLA/ poly(vinyl alcohol), and PLA/ poly(vinylpyrrolidone). Current research showed that with addition of other biodegradable polymers to PLA, the mechanical properties and flexibility could be improved, and the cost was lowered. The blends hold environmentally friendly characteristic and enlarge the application field of PLA materials in engineering plastics and packaging. |
