利用原子力显微镜( AFM)技术，研究超声处理及不同干燥方式对毛竹纤维初生壁微纤丝的影响。结果表明：经过不同预处理的毛竹纤维初生壁微纤丝都呈随机无序的交织状排列；与冻干初生壁微纤丝相比，气干的毛竹纤维初生壁微纤丝相互搭接得更紧密，纤丝之间的距离更小；超声处理增加了纤维粗糙度，并使得初生壁微纤丝暴露得更明显，超声处理提供了一个增加纤维表面润湿性和使竹纤维初生壁微纤丝更易被观察到的方法。因此，在利用 AFM 研究竹纤维微纤丝时，需要根据所要观察的目标特征来选择样品制备及预处理方式。

Moso bamboo fiber primary cell walls were analyzed with an atomic force microscopy to determine the effect of ultrasonic treatment and different drying methods on the arrangement of microfibrils and roughness of cell walls. The results showed that: the microfibrils in moso bamboo fiber primary cell walls pre-treated differently still arranged randomly forming a similar interwoven structure. Comparing with the freeze-dried samples,the microfibrils in air-dried samples touch each other more closer and the spacing between the microfibrils were smaller; ultrasonic treatment could increase the roughness and make the microfibrils exposed more obviously,which provided a method not only to improve the wettability of bamboo fiber but also to observe the microfibrils more easily. Therefore,it was need to consider the preparation and pre-treatment of samples when study the microfibrils in bamboo fiber cell walls using AFM.
