Abstract

Abstract:

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.

Key words: moso bamboo fiber, pre-treatments, cellulose microfibrils, atomic force microscopy
