摘要: 竹纤维是竹材的主要承载单元,其构造影响着竹纤维乃至竹材的加工利用。笔者利用原子力显微镜(AFM)的Peakforce QNM模式及Tapping模式对1年生慈竹纤维细胞横截面结构进行表征,对壁层厚度进行准确测量。结果表明:原子力显微镜是表征竹纤维细胞横截面结构的有效工具,适合定位表征竹纤维细胞多壁层结构及壁层的模量分布差异,并能够准确测量壁层的厚度; 竹纤维细胞壁层的模量不同,薄厚层相邻位置模量变化比壁层内大; 竹纤维细胞壁层数量以及壁层厚度因纤维所在位置不同而改变。

Abstract: Bamboo fiber is the main component of bamboo, and the fiber structure affects the utilization of bamboo fiber(from one year old Neosinocalamus affinis)and bamboo culm. This paper studied the polystructure of bamboo fiber and the thickness of each layer with Peakforce QNM mode and Tapping mode in AFM. The results indicated that: Atomic force microscope is a good technology for studying the polylamellate structure and modulus of each layer of bamboo cell wall, and the thickness of each layer in cell wall can be measured with AFM. The modulus of each layer in cell wall was different, especially in the place between broad lamellate and narrow lamellate. The amount and thickness of layers in bamboo cell wall varied in different place in bamboo culm.
