摘要:采用双螺杆挤出工艺制备聚乳酸(PLA)/乙酸丙酸纤维素(CAP)简单共混复合材料。通过力学性能、吸水性、扫描电子显微镜、动态热机械分析和热重分析等手段,研究了CAP用量对复合材料拉伸强度、微观形态及松弛行为的影响。结果表明,随着CAP用量的增加,其拉伸强度出现峰值,加入CAP使复合材料具有较好的力学性能,同时没有影响PLA的链段运动。
The binary mixing composites of poly ( lactic acid ) ( PLA ) / cellulose acetate proplonate ^(CAP ) were prepared by twin-screw extrusion process. The effects of CAP content on tensile strength, morphology and relaxation behavior of the composites were studied by mechanical property test, water absorption, SEM, DMA and TG analysis. The research showed that with increase of CAP content, a peak occured during the curve of tensile strength. The composites had better mechanical properties with adding CAE Meanwhile, the CAP molecules did not affect the relaxation activity of PLA chains.
