![]() The NPs were well distributed within the NCFs according to OLM and SEM, and FESM-EDX confirmed the presence of C, O, Si, and Ag elements. The degree of crystallinity increased after embedding. XRD revealed the presence of the semi-crystalline nature of PVA-UHMWPEO/ NCFs. The spectroscopic properties of the resultant films were investigated using x-ray diffraction (XRD), Fourier transforms infrared (FTIR), visible light microscope (OLM), field emission scanning electron microscope (FESEM), FESEM-energy dispersive spectroscope (FESM-EDX), UV/visible spectrometer, and LCR meter to investigate the structural, morphological, optical, and electrical characteristics. Core–shell nanoparticles were loaded into polyvinyl alcohol (PVA) and ultrahigh molecular weight polyethylene oxide (UHMW-PEO) blended polymer to fabricate new nanocomposite films (NCFs) using the developed solution-sonication-casting technique. Whereas this study used different technical totally that focused on developing new and green methods to obtain core shell nanoparticles through loading and mixing the Ag with blended polymers, they were then loaded with different rations of SiO 2 to surround the Ag inside the polymers matrix and then getting SiO 2 as nanocomposites.Ī green and easy technique was used to synthesize silver and silica core–shell nanoparticles (NPs) in the matrix blend polymers matrix. Most previous publications focused on the independent preparation of core shells, such as or SiO 2, then characterized their properties as nanoparticles. Recent publications reported several methods to syntheses or control the particle size of SiO 2 core-shell, such as using chemical processes to control the core size and silica spacer shell thickness of synthesized 2, a reverse micelle technique by coating the silver with SiO2 as a core-shell microstructure, a facile sol-gel process and heat treatment to the coating of YVO4:Yb3 + and Er3 + of SiO 2 as core shell structures.
