摘　　要：利用NaOH对小麦秸秆纤维进行处理,同时采用了不同的蒸煮助剂和改性剂,以改变纤维自身物理性能及其表面化学性质。将改性纤维与聚丁二酸丁二醇酯(PBS)共混,制备了秸秆纤维/PBS复合材料,并通过X射线能谱仪(EDS)、X射线衍射仪(XRD)和扫描电子显微镜(SEM)对改性前后的纤维进行了分析和观测,研究分析了助剂和改性剂对复合材料性能的影响。结果表明:秸秆纤维经NaOH/4%Na2SO3处理,以及碱处理纤维经钛酸酯偶联剂NDZ201、环氧树脂E44改性,所得纤维增强复合材料的性能较为优异。Wheat straw fiber was treated with NaOH,meanwhile different additives and modifiers were used to alter the physical properties and surface chemical properties of wheat straw fiber,and the composites were prepared through the blending between the fibers and poly（butylene succinate）（PBS）.Through analysis and observation of modified fibers by energy disperse spectroscopy（EDS）,X-ray diffraction（XRD） and scanning electron microscopy（SEM）,the effects of type and addition for additives and modifies on the properties of straw fiber and the straw fiber/PBS composites were studied.The results show that the property of the composite is better when the raw fiber is treated by NaOH/4%Na2SO3,and the NaOH treated fiber is modified by NDZ201 or E44.
