Sonochemical on-line synthesis and characterization of WO3/polystyrene nanocomposite

WO3 / polystyrene nanocomposite has been prepared by on-line sonochemical irradiation of an N, N-dimethyll-formamide solution of polystyrene and W(CO)5. WO3 particle sizes are from 20 nm to 50 nm and WO3 particles are distributed evenly throughout polystyrene. The nanocomposite materials are characterized by analytical method such as XPS, TEM, TG and FTIR. On the basis of the obtained data, a possible mechanism of the formation of nanocomposite materials is proposed.
