Acrylamide(AM) polymer microgels were prepared by an inverse suspension polymerization method. At room temperature, PAM microgel acting as template, Ag2Se-polyacrylamide(Ag2Se-PAM) composite microspheres with patterned surface structures were prepared by combination of a polymer microgel template method and a reverse micelle technique in presence of AgNO3 and Na2SeSO3. Scanning electron microscope (SEM), thermogravimetric analysis (TGA) techniques and X-ray powder diffraction (XRD) were used to characterize the morphology of composite microspheres, the content, and the lattice of inorganic Ag2Se. It was demonstrated that the surface morphology of the prepared composite microspheres was influenced by the initial concentration of AgNO3 and the dosage of the used surfactant. The patterned surface structure of composite microspheres were formed with the increasing the initial concentration of AgNO3; It was also demonstrated that the surface structure of the composite microspheres tended to coarseness with the increasing the dosage of the used surfactant.
