Nano-polydopamine-graphene oxide-TiO2 (nano-PDA@GO-TiO2) composites were prepared by dopamine modified graphene oxide (GO) and loaded nano-TiO2 on the surface of GO. The structure and morphology of nano-PDA@GO-TiO2 composites were characterized by X-ray diffraction (XRD). Fourier transform infrared spectroscopy (FT-IR). Raman. https://trendingcustomes.shop/product-category/2-layer-acrylic-ornament/
