摘要:

同步輻射原位X射線散射技術(shù)可以實現(xiàn)對材料結(jié)構(gòu)進行多尺度的、無損的、高時間空間分辨率的表征，動態(tài)地揭示材料微觀結(jié)構(gòu)在不同外界環(huán)境下的演變過程。X射線散射基礎(chǔ)理論已經(jīng)相對成熟。第三代同步輻射光源大幅提高了X射線散射技術(shù)的時空分辨率，進一步拓寬X射線散射技術(shù)的應(yīng)用場景。當(dāng)前同步輻射原位X射線散射技術(shù)的難點主要集中于實驗裝置設(shè)計和大數(shù)據(jù)處理。概述了X射線散射技術(shù)的主要分類和基本的實驗方法，主要介紹了不同分類的同步輻射原位X射線散射技術(shù)在納米材料（納米顆粒生長和納米顆粒自組裝）與能源材料（以鈣鈦礦薄膜材料為代表）研究中的應(yīng)用。最后結(jié)合當(dāng)前國內(nèi)外先進同步輻射光源的發(fā)展現(xiàn)狀，展望了同步輻射原位X射線散射技術(shù)未來發(fā)展的方向和應(yīng)用前景。

Abstract:

Synchrotron radiation in-situ X-ray scattering technology can realize the multi-scale, non-destructive and high temporal and spatial resolution characterization of material structure, and dynamically reveal the evolution process of the material microstructure in different external environments. The basic theory of X-ray scattering is relatively mature. The third-generation synchrotron radiation source greatly improves the temporal and spatial resolution of X-ray scattering technology, thus further broadens the application scenarios of X-ray scattering technology. The difficulty of the current synchrotron radiation in-situ X-ray scattering technology is mainly manifested in the design of experimental equipment and big data processing. This article summarized the primary classification and basic experimental methods of X-ray scattering technology and introduced the application of synchrotron radiation in-situ X-ray scattering technology in the research of various nanomaterials, including the growth and self-assembly of nanoparticles, and energy materials, represented by perovskite thin films as examples. Finally, combined with the current development status of advanced light sources at home and abroad, the future development direction and application prospects of synchrotron radiation in-situ X-ray scattering technology were prospected.
