聚乳酸(PLA)和木粉复合而成的PLA木塑复合材料,能有效解决PLA性脆、韧性差的问题,得到韧性较好的可降解复合材料。通过添加相容剂或偶联剂提高复合材料界面相容性,同时研究木粉组分、含量、粒径,得到PLA木塑复合材料增韧改性的成果,并分析研究了改性后复合材料的结晶性能,最后展望了PLA木塑复合材料的发展前景。
The composite of polylactic acid (PLA) and wood flour can effectively solve the problem of poor brittleness and toughness of PLA,and obtain better biodegradable composites with good toughness.The compatibilizer or coupling agent was added to improve the interfacial compatibility of composites.At the same time,the wood powder composition,content and particle size were studied.And the crystalline properties of modified composites were analyzed.Finally,the forefront of the research on toughening modification of PLA/wood composites was also prospected.
