Preparation of Hybrid Nanomaterial Polymer/MS/SiO2 ( M=Pb, Cd) Using Combining Sol- gel and Hvdrothermal Crystallization

A new kind of organic-inorganic hybrid nanomaterial Polymer/MS/SiO2(M=Pb,Cd) have been prepared by incorporating sol-gel process and hydrothermal crystallization technique. The as-prepared polymer matrix and Si-O network can successfully control the morphology of semiconductor nanoparticles and prevent aggregation. The existence of polymer can reinforce the thermal stability of composites. X-ray powder diffraction was used to characterize the nanoparticles, and transmission electron microscopy was used confirm that semiconductor nanoparticles were dispersed homogeneously in the silica and polymer matrix.
