摘要
采用反相悬浮聚合法合成了聚丙烯酰胺(PAM)高分子微凝胶,以其为模板,在室温条件下,以硒代硫酸钠(Na2SeSO3)作为硒源,制备得到了Se-PAM无机-有机复合微球材料,利用扫描电子显微镜(SEM)、X射线衍射(XRD)等手段对复合微球的形貌、无机物硒晶形结构等进行了表征。
Acrylamide（AM）polymer microgels were prepared by an inverse suspension polymerization method. At room temperature, PAM microgel acting as template, Se-polyacrylamide（Se-PAM）composite microspheres were prepared by a polymer mierogel template method using Na2SeSO3 as Se^2- ion sources. Scanning Electron Microscope （SEM）and X-ray Powder Diffraction （XRD）were used to characterize the morphologies of composite microspheres, and the lattice of inorganic Se.
