Abstract

Taking small-diameter Phyllostachys iridescens bamboo as the research subject, the morphology of bamboo fiber cell walls was observed using scanning electron microscopy, atomic force microscopy, and polarized light microscopy, and a qualitative analysis was performed. X-ray diffraction, synchrotron radiation wide-angle X-ray scattering, and small-angle X-ray scattering were used to quantitatively study changes in the microfibril orientation angle and orientation degree of bamboo, revealing the changes in the bamboo fiber wall morphology and microfibril orientation before and after microwave irradiation treatment. The results showed that the cell wall surface of the samples became smoother and more even after microwave irradiation treatment. Before treatment, the microfibril angle of the samples was 15.87°, with an orientation degree of 0.94 and an average micropore length of 29.3 mm. After treatment, the microfibril angle decreased to 13.18°, the orientation degree increased to 0.97, and the average micropore length increased to 59.7 mm. The microfibril angle decreased by 2.68°, the orientation degree of samples increased by 0.03, and the average micropore length increased by 30.4 mm after microwave irradiation treatment. These results indicate that microwave irradiation treatment reduces the microfibril angle and increases the orientation degree in small-diameter bamboo. This provides a theoretical foundation for the rational and efficient utilization of Phyllostachys iridescens bamboo.

微波辐照对竹子微纤维取向的影响
以小径楠竹为研究对象,利用扫描电子显微镜、原子力显微镜和偏光显微镜观察了竹纤维细胞壁的形态,并进行了定性分析。利用 X 射线衍射、同步辐射广角 X 射线散射和小角 X 射线散射定量研究了竹子微纤维取向角和取向度的变化,揭示了微波辐照处理前后竹纤维壁形态和微纤维取向的变化。结果表明,经过微波辐照处理后,样品的细胞壁表面变得更加光滑平整。处理前,样品的微纤维角度为 15.87°,取向度为 0.94,平均微孔长度为 29.3 毫米。处理后,微纤维角减小到 13.18°,取向度增加到 0.97,平均微孔长度增加到 59.7 毫米。微波辐照处理后,样品的微纤维角减小了 2.68°,取向度增加了 0.03,平均微孔长度增加了 30.4 毫米。这些结果表明,微波辐照处理可以减小小径竹材的微纤角,增加取向度。这为合理有效地利用箬竹提供了理论依据。

期刊介绍: Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
