Synthesis and characterization of US nanoparticles in polystyrene microfibers

We described the synthesis of hybrid fibers composed of cadmium sulfide (CdS) nanoparticles and polystyrene (PS) by an in-situ reaction method. Scanning electron microscopic (SEM) studies showed that the hybrid samples have a fiber-like morphology. Transmission electron microscopic (TEM) studies showed that US nanoparticles were embedded in PS fibers with a diameter from 10 to 20 nm. Fourier-transform infrared (FTIR), UV-vis spectrum and X-ray photoelectron spectra (XPS) were used to characterize the structure of the composite fibers. X-ray diffraction (XRD) results showed that a hexagonal US phase was obtained in the PS fibers. (c) 2006 Elsevier B.V. All rights reserved.
