Abstract
|
Development of novel inorganic-organic functionalised hybrid materials with their tailored properties has been receiving a great interest of researchers in last decade. These hybrid materials have their potential uses in various technological applications, depending on their organic and inorganic component.<br />Composite materials consisting of a semiconductor as inorganic component can lead their application in photonic crystals1, optical sensitizers, photo catalysts2 and light converting electrodes3 etc. Among other semiconductor materials, Zinc oxide (ZnO) has been considered technologically a sound material by virtue of its quantum confinement effects in experimentally accessible size range. It has been reported4,5 that polymeric particles are attractive templates for deposition of various inorganic materials due to their controlled dimensions, narrow particle size distribution, and controlled morphology. The aim of this study was development of the suitable method for the preparation of the hybrid particles consisting of the polymeric core and ZnO shell. To ensure the effective deposition of the ZnO nanoparticles, the surface of the polystyrene particles has been functionalized by â-diketone groups to bind effectively zinc ions which can later be transformed into ZnO nanoparticles. This strategy allows controlled<br />growth of ZnO nanoparticles on the surface of polymeric beads and provides effective control over the thickness and morphology of the inorganic shell.
