表面改性纳米硫化锌的合成及表征

Preparation and Characterization of Surface Modified Zinc Sulfide Nanoparticles

用均相沉淀法和原位聚合反应法分别制备了粒度、分散性和表面性质不同的2种纳米硫化锌,并通过XRD,TEM,热分析等分析手段对样品进行了表征.结果表明,原位聚合反应制得的PMM包覆的纳米硫化锌有机-无机复合率相对较高,具有较小的粒径,更好的分散性和稳定性.

Nanometer ZnS was prepared by two different methods, homogeneous precipitation method and in_situ polymerization method. The products' size, disperse and surface are different. The ZnS nano_powder was characterized by X_ray diffraction (XRD), transmission electron microscopy (TEM) and TG_DTA analysis. The results show that the ratio between organic and inorganic of PMM coated ZnS is relatively larger, and it has smaller particle size ,better dispersion and stability.
