In the present manuscript, an effort has been made to develop the curcumin ZnO nanocomposites(CZNCs) for their self-cleaning applications. Presence of ZnO and Ag/ZnO nanoparticles in curcumin matrix get confirmed by X-ray diffraction (XRD) and fourier transform infrared spectrometer (FTIR) techniques. Optimum transparency with tuned refractive index has achieved in Ag/ZnO-curcumin nanocomposite as compared to pure curcumin (Cur). CZNCs show minimum weight loss as compared to Cur sample. Core–shell formation has been further confirmed by selected area electron diffraction (SAED) and high-resolution transmission electron microscopy (HRTEM) studies. The major transition in water contact angle (WCA) to 15.25° for Ag/ZnO-Cur NC (Cur_ZnAg2) from Cur’s WCA = 40.55° has been observed. Conclusively, optically active, thermally stable, hydrophilic features based CZNCs can be utilized in self-cleaning applications.

核壳型 Ag-ZnO/姜黄素纳米复合材料具有光学活性、热稳定、亲水表面，用于自清洁应用

在本手稿中，已努力开发姜黄素 ZnO 纳米复合材料（CZNCs）用于自清洁应用。X 射线衍射 (XRD) 和傅立叶变换红外光谱仪 (FTIR) 技术证实了姜黄素基质中存在 ZnO 和 Ag/ZnO 纳米颗粒。与纯姜黄素 (Cur) 相比，Ag/ZnO-姜黄素纳米复合材料实现了最佳透明度和可调折射率。与 Cur 样品相比，CZNC 显示出最小的重量损失。选区电子衍射 (SAED) 和高分辨率透射电子显微镜 (HRTEM) 研究进一步证实了核壳形成。已经观察到 Ag/ZnO-Cur NC (Cur_ZnAg2) 的水接触角 (WCA) 从 Cur 的 WCA = 40.55° 的主要转变为 15.25°。最终，光学活性，热稳定，
