Abstract

A novel one-step soft solution-processing (SSP) route called solvothermal-copolymerization technique was successfully developed for in situ fabrication polystyrene (PS)/CdS nanocomposites embedded with CdS nanowires in ethylenediamine media at lower temperature (80-140°C). In this route, the polymerization of the styrene monomers and the formation of the CdS nanocrystallites occur simultaneously in a certain temperature range. The results show that the quantum-fined CdS nanowires with diameters 4-15 nm and lengths up to several micrometers via the present one-step route were embedded in the PS matrix and had [001] preferential orientation. Both temperature and solvent were found to play a key role in the synthesis of the nanocomposites. The produced novel hybrid nanocomposites display obvious quantum size effects and interesting fluorescence features.
