纳米纤维素的尺寸是控制其材料性质的重要因素。本研究报告了一种快速和稳健的方法，用于估计基于其水分散体的浊度的单个纳米纤维素颗粒的宽度。通过不同的方法制备了七种类型的纳米纤维素，包括短而刚性的纤维素纳米晶体和长而柔性的纤维素纳米纤维。它们的宽度是根据薄颗粒和长颗粒的光散射理论，从它们的水分散体的相应浊度图计算的。七种纳米纤维素的浊度衍生的宽度范围从2至10 nm，并且显示出与使用原子力显微镜确定的在平坦云母表面上散布的纳米纤维素颗粒的厚度的良好相关性。
The dimensions of nanocelluloses are important factors in controlling their material properties. The present study reports a fast and robust method for estimating the widths of individual nanocellulose particles based on the turbidities of their water dispersions. Seven types of nanocellulose, including short and rigid cellulose nanocrystals and long and flexible cellulose nanofibers, are prepared via different processes. Their widths are calculated from the respective turbidity plots of their water dispersions, based on the theory of light scattering by thin and long particles. The turbidity-derived widths of the seven nanocelluloses range from 2 to 10 nm, and show good correlations with the thicknesses of nanocellulose particles spread on flat mica surfaces determined using atomic force microscopy.
