采用不同的方法处理杨木粉，并对聚丁二酸丁二醇酯（PBS）进行共混改性，采用熔融法制备了PBS/杨木粉复合材料，研究了木粉含量以及碱化处理对复合材料力学性能的影响；研究了增容剂和邻苯二甲酸酐含量对复合材料力学性能的影响，并采用扫描电子显微镜（SEM）观察了复合材料冲击断面的表面形貌。研究结果表明：碱化处理有利于力学性能的提高，邻苯二甲酸酐质量分数达到30%时，冲击性能达到最大，增容剂质量分数为2%时，复合材料的力学性能最佳。

The poplar powder was treated with different methods,and polybutylene succinate(PBS)was blended and modified. Then we prepared PBS/poplar powder composites,and studied the effects of powder content and alkaline treatment on the mechanical properties of composites,the effects of compatibilizer,and phthalic anhydride content on mechanical properties of the composites. Scanning Electron Microscope(SEM)was used to observe the impact rupture suface of the composites. The results showed tha alkaline treatment is beneficial when dealing with the improvement of the mechanical properties. When the phthalic anhydride content is 30%,the impact performance is maximized. When compatibilizers mass fraction is 2%,the mechanical properties of composite materials is the best.
