![]() ![]() The synthesized samples were further modified by nanosized. Both the thermal stability and processing stability of the polymer nanocomposites were improved after adding the encapsulated ZnO particles. ZnO- nanoparticles were synthesized by a sol-gel technique from and tetraethyl orthosilicate (TEOS). A strategy was developed to overcome this shortage: the nanosized ZnO was covered by an inert amorphous SiO 2 shell to protect the polymer chains from direct contact with the active surface of ZnO. The pure phase of the ZnO nanoparticles (NPs) as anticorrosive pigments was synthesized by the sonication method. The porous surface of the shell acts as a carrier for sustained release of curcumin. ![]() The silicon shell enhances the photoluminescence and aqueous stability of the pure ZnO nanoparticles. We assume, that homogeneous SiO 2 shell on the surface of ZnO:Ga scintillating core heals the surface defects, thus contributing to the increase of RL intensity. The results indicated that the thermal degradation was accelerated by adding nanosized ZnO into the polycarbonate, the processing stability and performance of the material became deteriorated during the melt blending process and its eventual usage. The synthesised core/shell nanomaterial was characterized using XRD, FTIR, UV-VIS spectroscopy, Raman spectroscopy, TEM and PL analysis. RL spectra of ZnO:Ga-SiO 2 coreshells feature significantly increased intensity of the emission with maxima at 390 nm in comparison with pure ZnO:Ga particles ( Fig. The thermal property and processing stability as well as the optical performance of the nanocomposites were investigated. Enhanced chemical stability of VO2 nanoparticles by the formation of SiO2 /VO2 core/shell structures and. The nanosized ZnO particles were prepared and filled into bisphenol A polycarbonate by melt blending process. ![]()
