As a natural two-dimensional nanomaterial, palygorskite has been widely used in the fields of biology, chemical industry, medicine, and agriculture. Recently, more and more researchers point out that the aspect ratio of palygorskite directly affects the properties of its composite materials. Due to the large specific surface area and the tiny width of the palygorskite rod-like particles, it is difficult to obtain the aspect ratio information quickly and accurately by conventional means such as microphotography method and specific surface area method. In this paper, the length and width of the crystal is measured quickly and accurately by using dynamic laser light scattering technique and X-ray diffraction technique, so that the aspect ratio of the crystal can be calculated easily. It is recommended to analyze the crystallite size and microstrain of the diffraction pattern of palygorskite that using Pearson VII function, Caglioti equation, and average (LANGFORD) method, after comparing the three modes of W.-H. method. This feasible method has a good application prospect of the study of rod-like nanomaterials.

动态激光散射和X射线衍射分析技术测定坡缕石的长径比

坡缕石作为一种天然的二维纳米材料，已被广泛应用于生物学，化学工业，医学和农业领域。近来，越来越多的研究人员指出，坡缕石的长径比直接影响其复合材料的性能。由于坡缕石棒状颗粒的比表面积大且宽度小，因此难以通过常规方法如显微照相法和比表面积法快速而准确地获得纵横比信息。在本文中，通过使用动态激光散射技术和X射线衍射技术可以快速，准确地测量晶体的长度和宽度，从而可以轻松地计算晶体的纵横比。在比较W.-H的三种模式后，建议使用Pearson VII函数，Caglioti方程和均值（LANGFORD）方法分析坡缕石的微晶尺寸和衍射图样。方法。该可行方法在棒状纳米材料的研究中具有良好的应用前景。
