| 摘 要： | 利用异相捏合双螺杆挤出机，将铝酸酯处理前后的竹粉（BF）分别与聚对苯二甲酸?己二酸丁二醇酯(PBAT)共混，制得PBAT/BF复合材料。采用万能试验机、热重分析仪、扫描电子显微镜对PBAT/BF复合材料进行力学、热学性能和微观结构的表征。结果表明，BF表面经铝酸酯处理后，PBAT/BF复合材料的热稳定性和力学性能均得到改善，当铝酸酯添加量为1 %（质量分数，下同）时，PBAT/BF复合材料的冲击强度由6.7 MPa增加到9.5 MPa，提高了42 %，且断裂伸长率提高了92.7 %。

| Abstract: | The bamboo powders(BP)were surface modified with aluminic acid ester and then melt blended with poly(terephthalic acid succinate)(PBAT)to prepare a series of PBAT/BP composites through a heterogeneous kneading twin-screw extruder.The mechanical,thermal properties and microstructure of PBAT/BP composites were characterized by a universal testing machine,thermogravimetric analysis and scanning electron microscopy.The results indicated that the thermal stability and mechanical properties of PBAT/BP composites were improved due to the surface modification of BF with aluminic acid ester.When 1 wt%of aluminic acid ester was incorporated,the PBAT/BF composites achieved an increase in impact strength by 42%,and in elongation at break by 92.7%. |
