摘　　要：将自制的乙酰化竹粉与聚己内酯共混,利用转矩流变仪制备可完全生物降解的竹塑复合材料,考察配方和加工工艺对流变性能的影响,并研究所制备的竹粉/聚己内酯复合材料的力学性能和微观形貌.研究结果表明:乙酰化竹粉/聚己内酯复合材料界面相容性好,力学性能较佳;当乙酰化竹粉在复合材料中的质量分数为35%时,复合材料的拉伸强度大于10 MPa,断裂伸长率在400%以上.The acetylated bamboo flours （ABF） were mixed with polycaprolactone （PCL） by using the Haake rheometer. The microstructure and physical mechanical properties of the composite were studied. Results show that： the ABF/PCL composite prepaired by Haake rheometer owns excellent mechanical properties and good interface compatibilities. When the content of the ABF were 35 %, the tensile-strength of the material was 10 MPa and the elongation at break could maintain 400%or above.
