As one of the most advanced techniques to gain insight into the structure of the materials, wide-angle X-ray scattering (WAXS) records the scattering information at wide angles which typically larger than 5° (2θ), where contains abundant and detailed atomic-scale structure information of the matter. To improve the intensity and time-resolution, the WAXS can be further coupled with a synchrotron light source. The resultant technique, that is, Synchrotron WAXS can reach and even surpass the spatial and time resolution of 0.1 nm and microsecond scale, respectively, thus is very suitable for characterization of animal silks both statically and quasi-dynamically. This chapter would show methods to understand the structure-property relationship of animal silks by WAXS.
作为深入了解材料结构的最先进技术之一，广角 X 射线散射（WAXS）记录了大角度（2θ）的散射信息，通常大于 5°，其中包含物质丰富而详细的原子尺度结构信息。为了提高强度和时间分辨率，可以进一步将 WAXS 与同步加速器光源耦合。所得技术，即同步加速器 WAXS，可分别达到甚至超过 0.1nm 和微秒级别的空间和时间分辨率，因此非常适合静态和准动态地表征动物丝。本章将展示通过 WAXS 理解动物丝结构-性能关系的方法。
