摘　　要：采用改性剂改性后的玉米秸秆纤维增强聚丁二酸丁二醇酯(PBS),利用热压工艺得到了秸秆纤维/PBS复合材料;研究了苯甲酸、硬脂酸、硅烷、壳聚糖及乙酸5种改性剂对经超声波处理后的秸秆纤维/PBS复合材料性能的影响;采用EDS、SEM、FTIR及WXRD对改性前后的纤维及复合材料进行了分析。研究结果表明:5种改性剂对纤维均有改性效果,苯甲酸质量分数为2%～3%时,复合材料力学性能最优。Composite made by modified corn stalk fiber/poly butylene succinate （PBS） were prepared by hot-pressing technology,and the effect of five different modifiers such as phenylformic acid,stearic acid,silane,chitosan and acetic acid on the fiber/PBS composite was studied. Energy disperse spectroscopy, scanning electron microscopy,infrared spectroscopy and Xray diffraction were used to characterize the modified fiber and the composite. The results showed that every modifier showed some effects on the modified fiber. Compared with the different modifiers and its addition on the properties of composite ,found that when the acid content was 2 % - 3 % ,the performance of the composite was the best.
